Major points to Volvo for having an abs light to give you a hint but that customer wins the day for getting the symptoms precise enough to make it less challenging to diagnose. Great job and explanation as always. Anything that involves a zip tie is a win in my books!
In the US Army, that would be called a "field expedient" repair. Improvise, adapt and overcome the current situation. Well done sir. That was a great Christmas present for that couple.
Your customer looks so happy and probably relived that it does not need a transmission or something crazy expensive. Another no parts required! Excellent diag and video, Ivan!
@KevTech 1 Want to sell your 740 turbo ? I had a mistake 740 turbo that was originally ordered by the Belgium police department . A mistake car that was sent to the States . I cried when it got totaled in a rear end accident. It did 0 to 60 in 5 seconds flat with 280 K miles on it.
@KevTech1 jealous of that 740. I had one that I bought at just under 100k and drove all through my college years and beyond. When my then wife was pregnant with our first child, she insisted we sell it. Too old, old = unsafe, etc. Thing is, it was at 250k by then and the only things that had ever needed to be replaced were a water pump, belts, filters, and pads/rotors. Drove and idled beautifully. Started every . single . time. All the bearings, suspension, steering, etc. were still tight, and it was 100% fun to drive and massively practical. You can fit your whole life in a 740. I sold it to a student in NYC for something like $800 then as I had been ordered to dispense of it quickly. Today to get another one I'd have to shell out 20x that amount as they have become classics that people appreciate. 😞(yup, have looked). Absolutely bulletproof, delightful cars. Am on my fourth XC70 now (graduated to XC station wagons, wife is long gone so now it's just me and the Volvos 😀). Enjoy that 740 and whatever you do, do not sell it.
Nice solution :) I did something similar on a car I had a few years ago as a temp fix. Temp fix became permanent because it never caused any further issue so I ended up forgetting it needed doing!
I've had a couple GM vehicles that use the 4T40 transaxle where the output speed sensor connector gets corrosion in it and makes the transaxle shift weird and the speedometer fluctuate. Amazing how one little problem creates so many others.
It is pretty common in many cars for the ABS to be the primary source of the vehicle speed data. It is so, because as the ABS processes data from all wheels, it is still able to extract rather reliable real car speed data even when a wheel is losing traction.
Your explanation via service data towards the end is key. When you have an intermittent signal, it confuses the entire system. If you were to completely disconnect a wheel speed sensor, or even pulled an ABS fuse, the system would have ignored the issue as pertaining to traction control and transmission shifting. Traction control and ABS simply wouldn't have worked, but the transmission and other systems would have functioned normally. There wouldn't be conflicting data. I dig the Russian repair ;) It was either that or gobs of silly cone.
Ivan, I love this video. Back in the day we used bailing wire but life moves on and so must we. I'd give that zip tie a life way past 1000 miles! I think I'm laughing just about as much as the owner. Great way to start the day. Thanks for Sharing!
There's a lot of integration between systems on Volvo's that aren't always readily apparent. The V70/XC70 is superbly engineered and the mechanically they're surprisingly easy to work on.
When the dreaded "anti skid service required" msg lit up on the dash of the 4 cylinder turbo diesel S40/V50 and the car went in to limp mode, it usually ment that the EGR valve was faulty .. now go figured 🤔 owners were replacing their Ate ABS pumps for thousands of Euros, yet that didn't always fix the problem, just to later find out, that it was that silly 200€ EGR valve causing the headache
Wow that zip tie method just added a tool to my arsenal, the amount of times I’ve needed a zip tie mount but couldn’t find a good location, you just have me unlimited ideas lol
Hello! It's great to see that there are honest mechanics. Had that Volvo owner submitted his car to a Volvo workshop. Then they had started by replacing the entire gearbox, first. Then they had probably started to understand that there was a fault with the ABS sensor. At least the Volvo technicians who work here in Sweden. Thanks! From Tommy Bertilsson from Sweden
not just sweden its the same in uk , you tke your car in youve got a sticking solinoid or cracked bridge seal (£10) yes sir thatll be £2000 for a recon box oh and we want your old one yes the one that only needs a £10 bridge seal , with you tube and AI THESE PEOPLES DAYS ARE NUMBERED.
On this model of Volvo, cracked ABS rings are very common and can also give the identical random symptoms as you were experiencing....specially in the rust belt. Driving off slowly as well would be a temporary fix until the reluctor ring heated up at the break and expanded the gap too far for the ABS's liking and throw a MIL. The rings can be bought separately and tapped on to the CV joint. P.S. The early version of that gearbox also suffered from sticky solenoids.
int3eresting ,ive got a jag stype thats giving me a fault code for a relucter ring soon az i hit 20mph abs and traction light on. i carnt see any problem with the ring , BUT theres an issue with the zf gearbox DO you think it could affect the abs ?? i thought NO becouse its all seperate but now ive seen this???
strong work.. intermittent problems are usually intermittent connections! The "bricks" used to be known for alot of electrical problems due to crappy wiring harnesses. The insulation would fall off of the wiring so the whole wiring harness would need to be replaced. if u could get the wiring right, the engines ran for a LONG time., every time u turned 100k u could go to a dealership and they would give u a mileage badge for the front grill. I saw several 400 and 500 k grill badges back in the day.. especially on the bricks with the "red" engine.. they were legendary.
Hi Ivan . The lesson for me is , do periodic visual checks on your car . Because I do mechanical work on all my cars I’m lifting the hood and check automatically . Eric O did one the other day .And there was a bucket of grass on top of the motor?? Always love the Russian fix Ivan 👍🇺🇸🔧🛠⚒
Yeah, full system scans are vital. I had an Audi A4 in, two previous places had quoted for a replacement DSG Mechatronics unit. There was a code for internal processing error. They must have both ignored the ABS and traction lights and fault codes. It just needed a wheel speed sensor. My diag and repair was £2500 less than they had been quoted. And yeah, a new Mechatronics unit wouldn't have fixed it.
Well this was a great learning experience 😊 -the abs failing can reasonably affect shifting -how to make a hole in a connector to use a ziptie to lock it to the sensor Both blew my mind 😅 Thanks!
Hi Ivan, Another no parts repair. Like your method of deduction to find a potential cure, which in this case only required a zip tie. You and your family stay safe.
Outstanding job Ivan, it was accurate, quick and repaired in a short period of time. Hopefully the owner gets the replacement part and makes it a memory instead of it hanging over his head.
My dad taught me all about Russian Repairs. He was born in Estonia in 1918 and actual replacement parts for many cars weren't available. So yes most of my sensors are held in by zip ties and my purge valve is tied to the the line by a shoe lace... (on the road fix when no zip tie was available); I recall when he brought out a big chisel to remove a rusted frame bold and called it the universal "Russian Wrench". Eventually my friends and I started using the term "Russian Wrenching" for removing rusted nuts and bolts with a chisel. I still have on in my tool box today... 45 years later.... well that and a good hand sledge. Never doubt a Russian's ability to apply a low tech solution to solve the most complex of issues. Amazingly Russian armored vehicles still carry around a log for when they get stuck in the mud or snow and apparently it still works.
I’m going back to the days when Stromberg carbs and Red Blocks went together, B20 I think? The diaphragm failed miles from anywhere and it was raining. Differential diagnosis was applied, followed by much cursing. My travelling companion had a long look at the diaphragm, had a little giggle and dug out a box of cling film. The 3 layer, patch overlain on the diaphragm, was still going strong 3 years later when I sold the car.
Well done ivan a cheap/fast/smart mod as always from you :-D The inside of the car looks really nice. Shame the wheel support is not so good with rust. As you said it's a pain to get parts.
Awesome fix and info Ivan! 05 Subaru outback does similar strange shifting when I believe a certain wss acts up. I want to say it was the LF but it was throwing a generic vehicle speed sensor code which would illuminate the abs and cel. I was baffled after I fixed some wiring to the wss and the strange shifts stopped happening. The transmission still functioned ok but there were hard shifts unlike this Volvo. Very cool stuff!
I used to have almost this exact car, the only difference was a black interior - mine was loaded with all options (nav, keyless go, radar cruise control, etc). Awesome car - sold it because of terrible gas mileage..... These are absolute tanks - for parts I used to order from a dealership called Tasca in Rhode Island even though I am in California.... One thing that gets overlooked on this cars is that the rear diff needs to be serviced with special fluid from Volvo - super important as there is a seal that can fail if not replaced.
Depends, 3.2 and 3.0 T6 engines get just shy of 30 MPG highway.. urban/city mileage however is trash, mid teens. That being said, The 2.5L T5 engines are horrendous for gas mileage full stop, as any true C30 T5 owner/lover. As for parts, I personally use and strongly recommend FCP Euro and IPD Volvo. ;)
Just drove 500 km highway trip, with my 2000 V70 2.4T automatic, winter tyres. 34 mpg. City driving takes more, but a lot of depends on how heavy is you foot on gas pedal...
Coincidentally, EricO just put out a video diagnosing a disparity between a Toyota Tundra transmission output speed sensors, but that one needed a part. 😉
This happened to my mother’s 2008 Volvo S80 T6! Same failure except it was the left rear sensor plug. I replaced the harness connector after first zip-tieing it together, and it’s been fine since. Also, if you work on one of these in the future and want to try pulling the ABS fuse, don’t bother - the car won’t start if you do.
Very interesting on the fuse pulling issue. I wonder if it 'matters' which fuse you pull. I imagine if 1 got pulled that shuts down a network, then yes, there could be a no start. For my part, be it a GM or whatever, I simply disconnect a wheel speed sensor to disable that system when they're affecting other systems.
@@adamtrombino106 After that repair I learned that on P3 Volvos four modules make up the immobilizer: ECM, TCM, CEM (Central Electronics Module), and BCM (Brake Control Module). All four must be present and communicating on the HS CAN for the start to be authorized.
The doom of interactive modules - a minor ABS problem causes a major transmission problem, due to an algorithm that compares wheel sensors before shifting. The most gratifying is that there are no parts available and a zip tie solves the problem :-) Cool NPR, Ivan!
"Smekalka" came to mind as you "manufactured" your own fix for that snapped plastic tab on the female speed sensor plug housing! It brought my back to so many memories of my childhood. We used to use the term "ghetto-rig-it" where I grew up. I grew up in a rough neighborhood, it was a well known as the "projects" in my city. The running city joke was "They don't have hot water there" and for good reason. They bulldozed it not to long after my mother and I got out. A few years later I ended up in a state technical high school. I was always blessed from a young age with the curiosity of all things mechanical and became quite mechanically inclined. In that place I knew that kids with "idle hands are the devil's playground". I would have instantly been bullied and beaten up the moment I moved there but coming from a much softer background beforehand. In using my knowledge I helped all the neighborhood kids bikes stay fixed and also introduced myself by letting them ride my homemade mini-bikes and go-kart from a old stripped yerf dog frame. I fitted it with a snow blower 5hp briggs & stratton. Anyways I would either end up breaking the pull string for starting it or lose the whole pull starter altogether a lot. No side plate coverings on my motors! So I would improvise starting it by tapping a nickel or quarter in the clutch (depending on how already worn out clutch disk was). Then I'd have the neighborhood kids push to "pop start" the motor. We'd lose that plastic starter fairly often when taking sharp turns running from the cops in the city. Whenever they would break down word got out in the neighborhood our shady neighbors would always help out. When the throttle cable broke I used a brake/shifter cable that was "donated" from an old mountain bike. You used what you could get. I look back and it amazes me what we could do with all the scrounged up parts we could get. We would always get it done. From my milk crate basketball hoop to the useful bolt cutters used to cut a hole the fence to retrieve the ball when it would go over the fence. From "donated" junkyard wheel bearings to bike inner tube patch repairs. You learn to be very adaptable growing up in an environment like that. I'm forever grateful to be one of the few kids from my childhood to make it out of that place. I was blessed and fortunate enough to be inquisitive and excel in school & sports later on in life. I ended up on a positive path. Most of my brethren didn't later on in life. I was lucky, but that the place I grew up in did shape the person I am today. Fortunately the positive aspects are what I (primarily) focused on and took hold of. Yeah I've made my fair share of mistakes. Still despite my environment growing up, I had a decent head on my shoulders and good parents; guidance. All of it got me to where I am now. Very few of those kids had that growing up there. I am forever grateful for that. My life now is worlds away from that daily drug & crime infested place where I grew up.
THANK YOU! While I am not having this problem with my 2013 XC70, it is great to know just in case it happens to mine in the future. I wonder what a stealership would do if you presented the car with these symptoms? I'd guess they would try to sell you a very expensive transmission overhaul or replacement.
Great! Love those no parts required fixes! The dealer would of replaced the entire control arm assembly (sensor rusted in place or PIA to the arm) and probably a new wheel bearing charged over $2,500 in repair cost! for a repair a 2 cent zip-tie can fix!
It's very rare to see one of those clips break off. But it does happen. What I usually get is when someone has done some suspension work or replace an axle and they forget to properly torque the axle bolt and the bolt later walks out. Letting the CV slip in and out of the hub as you drive. Causes an identical problem. But yeah, pro tech tip. Volvo's with random transmission issues, check the ABS system first. Nice work with the zip tie. That would make David Freiburger proud. lol
Ha! I've seen cheap Chinese aftermarket axles do that on a Volvo. No matter how hard you torqued the axle bolt, the slop in the splines would gradually walk it out and the problem would repeat again xD
@@PineHollowAutoDiagnostics I've seen something like that on a BMW recently with a cheap aftermarket axle. But it was the supplied axle bolt that was just a little too long and the spring on the end would not apply enough pressure to fully engage the axle to hub teeth. What a horrible grinding sound it made when you leaned on the loud pedal. LOL
As soon as you said abs light with transmission shifting problems....... Straight away went bad sensor. Seen that a few times. Excellent repair though.... Keeping that one for later repairs.
Wow, a loose connector in the abs could cause the trans go funky. I guess it's a Volvo thing lol. Nice repair of the zip tie!! Great video Ivan, many thumbs up!!
on a BMW the speedometer signal actually comes from an abs sensor. Thats where I thought we were going with this one. Well done , only one part required, zip tie! Great as usual
yes usually left rear. ABS/DSC all dependent on a freakin wheel speed sensor that lives in a dirty, corrosive, bumpy enviorment.. made for the autobahn, not pothole america.
As soon as I heard Ivan talk about the ABS light, I was already going "Yep, wheel speed sensor". Those are pretty simple parts and they're in a hostile environment exposed to dirt, moisture, vibration and what-not, so they're going to fail sooner or later.
Ahhh the classic Section J page 7 ABS connection repair using heated instrument. A tale as old as Volvo history. Gotta love the classic literature Ivan. Yet another NPR amazingly.
I had a similar issue with an E34 530i bmw. Fitted spare wheel to the front which was more worn than the opposing front wheel. If I caused the engine to change down it would stick in the lower gear, thinking it was going around a corner all the time due to the difference in reported wheel speed. Too clever by half !
The tone rings rust and crack. My diag tool shows the actual signal from each wheel sensor graphically so it was easy to diagnose (cracked ring). The code also indicated bad signal. A replacement axle that includes the tone ring was the most expedient repair. Nice zip tie repair too.
In my experience there are many cars that go into limp mode when there is abs fault. The Ford explorer will need a roll back to get you home, GMC Acadia won't let you drive above 40 MPH, and the list goes on and on. Manufacturers have engineered the software to do all this so you all will fix your cars and not just defeat or ignore the trouble lights.
I really appreciate this video. Although I drive a Lexus now, I have always been a diehard Volvo fan. I had an S70 for 19 yrs and the engine was still going strong. It was the cosmetic issues and sunroom rails rusting that caused me to trade it. It was the best car I have ever owned in terms of ride quality and reliability. P.S. Maybe your zip tie fix could have helped my failing sunroof rails. 😎
I think it's the same with 2000 Volvo V70 I have. Around 2000-2004 models ABS unit made by ATE fails due cracking lead free solder joints at the connector. I start losing the signal from driver side from ABS sensor. AND sends the speed to Cruise, DIM (Driver information module = speedo) and TCM/ECM. If you get stuck in the snow and only one wheel has traction, this function prevents the transmission upshift. Thus on so inexperienced drivers, who floor the accelerator to get unstuck do not get one wheel spinning 100 km/h when the tire meets the tarmac and car jumps forward and/or gearbox might get damaged. Normally traction control would prevent this by braking the faster spinning wheel, BUT if there is no speed info from both front wheels is is disabled..
I had a BMW 328i wagon with the offset tires, skinny in front I think 225, wider on rear 235 or 245...they were switched/rotated and it caused a Tranny fault. Corrected the tires and it cleared up almost instantly.
Volvo's Amazon ranking climbed from last to second to last after Ivan proclaims they're solid cars although they still hold last place out of tradition.
Crazy I have an 07 mini cooper this past summer the car bucked and I watched temp gauge pegged hot close to home I knew it was to soon to be even to be at operating temp. I turned around and limped the car home bucking and running bad, When I got to the house I checked the coolant and yes I opened the cap full not to hot. I started looking around and found the temp sensor connector loose with a broken tab at First I though no way plugged it back in and drove the car no issues I replaced the connector and have had no issues since.
Привет Иван! Почему не поверим в такую причину сбоя AT, очень даже логичная и типичная проблема. _________________________ Сегодня, мой сын Иван, поставил тебе, свой первый лайк. Поздравляю тебя!
It's true that many systems in these cars are interrelated. Fi. If something is wrong with the throttle body or ABS the cruisecontrol, TCS, ESP will not work either. Transmissions in these are Aisin-Warner gboxes that use electonic control. According to Volvo these gboxes are filled for life ( which IMO means until broken) and the valve body in these AW transmissions wears out, causing shift flaring followed by violent gear engagement. These gearboxes benefit from cleaning flush and new (special spec!) ATF. After that is done the relearn procedure has to be done. VIDA software needed).
This is why I always keep a half dozen zip ties in my moto backpack, and a bag in my car's glove box. Just never know when they're going to save the day.
Had the screw on my brother's wheel speed sensor snap off in the hole, there wasn't a way to drill it and tap it due to rust. I put the sensor in, and slapped a teaspoon of JB Weld on it. 4 years later it's still there lol.
Ivan that model is equipped with DSC (dynamic stability control) There is a switch on the central consul for disabling the DSC. Pushing that switch will let the car drive as normal. They are bad for sensors and tone rings splitting. Nice video.
they are usually already disabled due to dirty or broken wheel speed sensors, seized pre pumps, broken solder joints in DSC module, stuck valves in the ABS unit, and on and on. just changed my pre pump in a 2000 bmw z3 and it was a 2 day saga . hope its worth all the work and money to get the DSC working . took alot of research to even partially understand how the system works.
