I’ve watched a lot of Eric,s videos & I must say he is one heck of a tech ! One of the best at his craft . We need more techs like him ! I’ve gained a lot by watching . He is the wizard at auto repairs . Vechicles now days are so complex anymore unless you have the right tools to the repairs . Tools can get $$$$$ as we all know .he does have a good sense humor too ! He really is a great educator !
Love your stuff Eric O, I have learned a tremendous amount from you. Great editing and yes I do know how much time goes into this side of things. Agree with your comment at the end re complexity etc. But you are correct we must move with the times, even though I sometimes long for the days when the biggest issue with a Chevy truck fuel pump exchange was trying to keep the pushrod from falling out of the block, yes I'm an old guy!Thanks again.
That Bosch J2354 is nice and will pay for itself. I use the Launch J-Box and has yet to fail me. I have done programing on many different vehicles from Ford and GM to BMW and VW. Great repair and video. Looking good Vanessa with that hair cut.
What a true statement getting more difficult by the day, I spend more time reading and learning then I ever had, it is a changing world. And when customers walk in the door they expect you to know what is going on. Always got to stay sharp!!!
I am actually a GM dealer tech, and this video really intrigued me. I had no idea that anyone could access tis or sps, I also had no idea that Bosch made any version of the mdi for anyone but dealers. FYI, the ‘‘tis site you are using looked identical to what we use at the dealership, except we access it from a GM site with GM logins as apposed to the acdelco site you went through.
The funny black plug on the back of the module is actually a vent so that any excess pressure won't blow out the seal between the edge of the circuit board and the housing.
I'm amazed at the level of technology that is required for vehicles these days. Is the Bosch tool fairly new to you? That adds great capabilities to the shop. We'll done Mrs O.
Probably a case of Silver Ion Migration causing a short circuit like in the recent instrument panel video :( Being broke with nothing to lose I would crack it open and check the drivers, re-touch the solder joints and clean the board. The IP folks mentioned an acid wash (maybe vinegar or oxalic acid?) would kill those pesky invisible ion trails. Worth it for me to try as I *hate* having my truck held hostage to keep inept stealership service deptartments in business.
pinfarmer Did you watch the videos? I posted them, agreeing with and citing what the other Poster had said. Yes, RoHS solder is very bad. It does not belong in sensitive equipment.
Before they had a fuel pump they either had a thing called an Autovac --- that used engine vacuum to pull the fuel through or even simpler had gravity feed. Ford Model A had gravity feed if the fuel level was getting low it would stall going up a hill, unless you went up in reverse.
Hey Eric, it's been my experience when programming ECM's (update or replacement) that you don't need to do a crank relearn unless the ECM stores a code, on GM it's usually a P1336. It will turn the SES light on and let you know.
Another great video Mr O, well things have moved on as far as computers and cars go, days of fixing your vw with a beer bootle cap are over :). I think their room for a Mrs O's tip section in your vids...Still thanks for taking teh time to share, given you have a business to run as well, much appreciated. - Rob
I've had problems using a battery "charger" because the voltage coming out isn't clean. You need to use a battery maintainer where you can set the voltage. Gm likes the voltage to be under 14 volts or they can brick a module.
Nice troubleshooting and fix. Lots of stuff crammed in that little black box. Wonder if all of those parts are needed and if that black box is really better than a fuel pressure regulator. Thumbs up video.
Well it is all about emissions and keeping fuel volatility low on a return-less fuel system. The less we can agitate the fuel in the tank the better. Less hydrocarbons :)
Having same issues with my Yukon! I’m about a thousand dollars into throwing parts at it !!! I’m going to check my black box tomorrow For any broken wires or corrosion
Great vid once again, Dr. O! It is indeed crazy how connected modern cars are, and the amount of programming that sits inside each one. That Bosch unit looks mighty nice! And it should, as it looks to be exactly the same hardware as the GM MDI module, except green instead of blue. Even the VCI Manager software is identical to GM's MDI Manager! Obviously Bosch licenses their design to many companies, just like we see in other automotive systems nowadays. That TDS site looked awful familiar, too! I had to login the other day, and had a chuckle at the news item highlighted in red. Wonder what's up with those 1.4L turbo motors! haha. Keep up the good work and fighting the good fight!
If the repair is too expensive they don't want junk a car with a full or half tank of fuel. Dr. O is usually the last chance before it goes to the boneyard.
Hi Eric and Mrs O. Well I guess for this one you could do it and I can not. You went way past the capabilites of the home garage mechanic in this one. As you say getting tougher and tougher just to keep up with being able to repair the basics. Great video and repair computers needed for just about everything now. Keep the videos coming Brian & Shotty
While new cars are less and less user serviceable. I remember vividly owning carbureted, mechanical fuel pumped, point ignition vehicles with drum brakes in the front, etc... You cussed them when it was hot, you cussed them when it was cold... I am happy to leave those experiences in the past, cars are way better now. Longer lasting, more reliable... You just really have to find yourself a good shop that you can trust when you do eventually have issues.
the guy just wanted a sticker for his windshield so the cops couldn't give him a ticket, and that must be the get a sticker for the windshield procedure. Great follow up vid O, that interface seems to be working well, good to see Mrs O, got to keep up with scanner danners lady.
I always had fun and games trying to get TIS to run at different Holden dealerships. Got a whole lot harder when they switched to a bluetooth interface.
hey eric, nice vid...be carefull about cutting power to a module thats not programmed....like when you turned the key off ; per instructions to do so...if the new module is already installed do not turn the ign off, iv seen plenty of modules rendered useless because of just that "following on sceen instructions" just remember once you power a new gm module, if it hast to be programmed, you must not loose power to it before it is programmed. bill
That little rubber plug on the bottom of the fpcm can also double as a drain plug. I've come across a ton of them full of water. green ooze and swamp water pours out. Most of the modules under those c/k trucks have major corrosion issues. That rubber plug has been the culprit more often than not.
Don't know what VCI you use now but the drew tech cardaq plus 2 and the cardaq M are awesome. You can use them to flash program and also as an interface for tech2win, GDS2, and many other manufacturers diagnostic software including Honda, Toyota, BMW and several others. They are great and I haven't had a failed reprogramming event since I've started using it.
There is no doubt, that Fuel Pump Control Module is a money maker with the location at the rear of the truck! Ya, I remember the cam shaft pushing on the fuel pump actuator rod that pushed the fuel pump arm! How about this. A "Double Acting" mechanical fuel pump. The upper part was connected to the "Vacuum Wiper Motor" and the intake manifold vacuum port. It helped keep the wipers going when you floored the gas pedal in a rain storm. Without the D. A. Fuel Pump, the wipers would stop when the gas pedal was pushed down and/or floored! Thank God for electric wiper motors! Oh ya. The lower part of the pump handled the gasoline "transfer" duties, from the tank to the carburetor. System worked great until the cam shaft wore down! I saw that module on our 2011 GMC Silverado's with the 6.0 or 6.2 Liter V8's. Strong running truck, LOVES GAS! Showed how much in the low gas mileage! I supposed it was cheaper to put it at the back to control fuel pump power, instead of a logic module up front and a power module in the rear connected by its own CAN or GMLAN! Although, they do use the PCM to control the FPCM logic. To many acronym's ! ! ! Hey! More s**t to complain about! There is a plus to all this! It's after midnight, and I gatta get some sleep! Good night! (Great video!)
hey eric great video alway looking forward to what your diaging next .. so question... would your autel with the programmer been able to reflash that module for you or what are your thoughts on using that actual scan tool in this case
I fully agree with how overly complex cars are these days. And Mrs. O., don't put up with Eric's lip! I use the pliers trick all the time, and the cardboard trick NEVER.
No No, you got it all wrong. It's bubble gum all the way. That way when using either a nail or screw your washers, sealers or gaskets, no longer needed. And never be without, since there's always some under a desk or table and occasionally on bottom of your shoes.
The surface mount capacitors inside the black box are only rated for 1,000 hours. They're way out of spec by now. Typically used in modern lcd televisions. Length of warranty= 1 year = 3 hours average usage x 365 days = 1,000 hours.
@@robertwhite6203 and i been looking at the programs hes running and you cant even buy the software, its like some kind of rental , $575 for only a year.
Eric, this is the future Electronics the big car companies are trying to put the little shops out of business, more job losses more dependency on the government for monetary help. good luck buddy
that could be disputed saying this video is also proof that things are moving in the right direction. this is a small shop, and a computerized component requiring dealer type programming was just replaced. if it wasn't for these types of tools (and legislation requiring automakers to make their software available to the public) then this would have to be done at a dealer.
Car companies make their money by selling parts and access to information. Dealers are independently owned and make the money off of the labor. Car company gets paid regardless if it is the dealer or independent shop buying the parts and subscriptions. Henry Ford said he would give everyone in the country a Model T if they would all agree to buy Ford parts.
The right to repair act allows the aftermarket all info that the dealer has. If aftermarket shops can't fix them it is because they don't know how or don't want to know. It is just the way it is.
Well, a four year old battery an alternator with 200,000 miles on it and I get a flat battery, bought a battery at a shop and ordered a remanufactured alternator ~ diagnosed and verified with your help and the help of many on youtube ~ oh! btw, I fitted it myself ~ I'd hardly come across the pond for a fix, but a local garage has been done out of €200 plus the parts, I believe I can, I believe I can ...... :)
Nothing. They come with no programming in them. Think of the module as a new computer (which it is) that has only a basic operating system. You need to load in the proper information to make it work. The VIN tells GMs network which options the vehicle has and the it programs the module to match.
It would have to have all the same options as well. Most modules these days are very vehicle specific, even a fuel pump module. In the end using a new module is probably cheaper when everything is considered.
Have a 2009 Colorado with same issue. Although we have a FRPS reading 90psi and pressure at the port is 90psi I have a Ultra Elite and for what ever reason I could see FPM data but could not control the fuel pump out put. Another odd pid is ignition voltage was reading zero. Everything leads to a bad FPM. Ohms at pin 2 was less than 1 ohm. 5 volt ref was good ground was good. Of course its New England and the spare tire is locked up in position and everything is heavy scaled rot.
My next "new" vehicle is going to have the camshaft/pushrod fuel pump, a carburetor and points! Man this sort of thing burns my ass! Just when I though I had spent enough money on that Autel Maxisys, now I need the J2534 ... and if that wasn't bad enough, I have to send even MORE money to GM to download their extortion program! I'm trying to get with the times, but boy ... I DON'T LIKE IT!!! GRRR ... Thanks for showing that programming procedure. Heck, had I not seen this vid, I probably would've ran into something like this here eventually, spent $175 on a new magic box, plugged it in, turned the key and got NOTHING! I'd have melted down. I see there are lots of things that require programming now - even the HVAC ... WTF! What's another couple grand for a Microsuck laptop, and the pass-thru module ... Everything today is designed to bleed us all dry. Maybe I should just dump my Silverado and get me that '69 Grand Marquis convertible ... and a trailer hitch. :D
Problem is you can´t just do it yourself, they want you to bring it in for a few days, pay for a loaner etc etc.. because of that shit programming. And you can´t just get used parts for the same reason... over here most Dealers refuse to Programm used parts
bobl78 absolutely! Eric said it all when he said that it used to be that all you needed was just an ignition switch and relay to power fuel pump. There is a crazy overuse of electronics and programming on simple devices; on some cars now the operation of the rear lights is via a module; this is complexity for complexities sake. Note in Eric's fix here it was not the pump or anything physical that had gone wrong but the device/sensor used to monitor it.
Companies in the 21st century seem to want to take your money by extortion, rather than EARN it on merit. I see lots of parallels to our current government administration ... Sad times we live in!
I'd think the main reason for this "over complication" is an attempt to meet fuel efficiency and emissions guidelines. Anything else is secondary. In this example they had a goal to make a returnless fuel delivery system and what they came up with is a system that controls the pump duty cycle based on calculated fuel demand that is separate from a likely existing ecu. I'd rather have multiple modules that are individually cheaper than a monolithic control.
The whole issue with the fuel pump module is emissions related (isn't every thing?) First, designing variable displacement pumps of any kind is difficult. In almost ALL applications a pump is design to be oversized for even the worst case application and excess fluid is just sent back to the sump. With the old vacuum regulated system did just that. The problem with this design is that when an engine is idling (like in a traffic jam) 90+% of the fuel is sent back to the tank. After extended idling the fuel in the tank is hot. Hot fuel gives off vapor. More vapor than the vapor management system (charcoal canister and purge vale) can handle causing the over pressure valve to open and vent to the atmosphere. CARB and EPA are unhappy, Design a reasonably priced pump that can maintain a constant pressure by varying the volume WITHOUT electronic controls or a bypass regulator and you will be a billionaire !
Thought this was an auto repair channel, not a computer channel. Lol just kidding. There's more computer crap in automobiles now, and it's getting worse. Nice vid!
"Cause you know dang well everybody at home is like- oh I would have opened that up and done whatever it is I do." LMAO... Priceless words of wisdom. TY Eric.
