I have been working on cars and trucks for about 32 years and made it to Master L1 and I must say that I couldn't have done the job any better than you have. This is an excellent video for anybody that might possibly need to learn how to do this the proper way.. Hats off to you sir on the excellent video job well done! MD

Stil loving these older diags. Thank you for providing all of this very valuable content. I have a friend here in OKC that is a crack Chrysler tech. He’s commented to me many times that those vans have that “contact point” where the harness can run on the motor mount in that same area. Key words that run through my mind.... points of contact, loaded circuit testing, voltage drop and vest of all “test lights are your friend”. Solid Gold.

@ScannerDanner 3 года назад

Thank you so much! You've been clearly paying attention 😀

@chrispritchard4676 6 лет назад

Thank you for your excellent video. I have had a Grand Voyager for 13 years with a TCM occasional fault. Four "specialist" transmission garages have investigated and been unable to locate my fault. However with your video I know I can locate the problem and get it sorted at last.

@NatHan-mi2lj 10 лет назад

Great video! No two techs tackle the same problem exactly the same way, but some how your way is the right way. I do this kinda stuff everyday and it's fun to sit back and watch the puzzle unfold without having to do all the leg work. Your diagnostic process and reasoning are top notch, keep it up!

@torineg.847 2 дня назад

I just got a 2006 T&C and was having problems with it not shifting. My friend has a scanner and the location of the relay. We were gonna do the test light first then decided to put another relay in exchange. He cleared the ck eng light I tried it and now shifts in all gears. Thank you for your informative video. It made my day that much brighter. Now I got to tackle the right turn signal not returning after turn is made and also the two sliding doors are not locking or unlocking but when you manually unlock the doors the auto open and close works good but just won't lock. (?) Again Thank you

@Derabjee 9 лет назад

A very good example why you should always test your circuit loaded and unloaded. Many people forget this and because they don't test it loaded they're not aware of a possible voltage drop. Great video! As always.

@SimplyDiagnostics 6 лет назад

This must be the 4th time I’ve watched this video. The case for loaded circuit testing doesn’t get any stronger than this video. Awesome 👍

@ScannerDanner 6 лет назад

Thanks for the reminder about that for when I start class next week :-)

@louiskogok8940 Год назад

Excellent video! The voltage is a piece of the puzzle. The Loaded circuit showed the piece was defective, which led to solving the puzzle ; the wiring. That sure looked like a lot of wires living in a bad environment, under a vehicle. Some one told me once that the best tools in a tech's toolbox are not in the box. They are his mind, hands and his eyes. You saw the retape. You saw the zip tie. Tenacity prevailed. That's what I love about you videos Paul ; The unwillingness to concede until every possibility has been considered and checked and rechecked. To me, it is a beautiful thing to see! Thank you.

@@ScannerDanner Wonders happen, today is a crazy day! I've power-washed every bit of the wheel 'arch' (sorry for my English), including all that messy wiring because I was stuck in mud up to headlights two days ago... And after all that washing and wiggling of all that terrible-looking wire harness and TCU, my Chrysler Voyager (same car as in your video, but made in Austria, as you probably know), suddenly had no Check Engine light, no limp mode, and now shifts perfectly, without any 'bumps', etc. This only proves that there is a bad wire/connection somewhere. For now, I skipped the 'surgery' of the wires, since it looked too overwhelming. I will prepare myself better mentally for the next time when limp mode happens (and it will happen, for sure). This simply confirms that you were SO RIGHT in this video! Oh, and of course, it is a huge pleasure to receive your reply from the other part of the world and after so many years after the video has been posted! Mega cheers! :)

Thank you! Thank you! Thank you! I had the limp mode problem back in January. Took it into the garage and they said it was dirty connections on the PCM. The problem came back this summer. I sprayed all the PCM connectors with DeOxIt and no improvement. I found this video. I had problems with three other relays in the past few months. I had one spare left. I go out, replace the relay, go for a drive and BINGO! It's shifting again! Dealers and parts companies want $37-$40 Canadian for the relays. Rock Auto $15. SO I had bought three from Rock Auto after paying $37 for the immediately needed one. Anyways... Thanks again! My van is back in operation. BTW it's a 2005 Dodge Grand Caravan 3.3L.

@realtoy1 9 лет назад

As usual great video. I have noticed in your videos you teach how to work with what you have to perform tests which is great. After being in the automotive repair field for a little over 30 years I am constantly looking for new and better ways to approach testing and repairs. Another method is to remove the relay and rap single strands of wire around each of the pins then reinstall it in the relay box. This must be done with caution because of the potential of short circuiting the circuit being tested. I found this method in a video here on RU-vid by realfixesrealfast called "relay test." I have tried this method and it works. It is a little time consuming, but it works. I recently purchased the Lisle 69300 master relay test jump kit to save time and I highly recommend this kit. Great job and keep up the great work that you do.

Hey Bro. I loved that it truly shows how simple somethings can be to get a vehicle back on the road. Sometimes it's not always about throwing expensive parts at a vehicle. As mechanics we can show the customer that they can have confidence in us to be honest and fair to repair their vehicle and where we didn't gain in a big job to day will lead to dividends from word of mouth of being honest, reputable and fair, because word of mouth goes both ways.

@mctobbsi 11 лет назад

A very nice job as usual Paul! You make it look so easy finding a corroded wire in a harness. But I guess that wire harness problems are rare when the protective conduit and tape is intact. And if you find indications on a problem with the insulation that is probably where the fault is.

Hello friend. The test light I was using in the video I bought from Sears over 10 years ago. Not sure if they still make them. I looked on their site and didn't see it. Any regular style test light will work. Just check your current draw of the light so you know for future reference. Most of the incandescent style lights will have around 200ma or less.

@terryeffinp 6 лет назад

I used loaded circuit testing on a daily basis. I am a big fan of voltage drop testing as well. I use to use a test light in conjunction with a multimeter. Now I have one of those fancy loadpros. It is okay for testing low current stuff. I still use a headlight bulb with a mulitimeter for high current circuits. For certain applications I have breakout harnesses that I can connect my meter in parallel with the component without backprobing. I find it amazing that most manufactures are not okay with using a test light even though it often leads to misdiagnosis. A lot of the modules that are used in my industry are protected with smart FETs or some kind of current limiting device. They have to be because eventually you will have a short to ground on an output driver and there has to be some type of internal circuit protection to prevent damage to the computer. I do like to use OCV for wiggle testing a wire if the wire is in bad enough shape. I am not an automotive tech but your videos are always interesting to watch. Keep up the good work you are helping out a lot of folks on here.

@waqasazmat81 6 лет назад

It makes sense, voltage is available up to the open point (relay pin 86). As soon as the circuit is loaded voltage gets shared with the other unintended resistance in the circuit, in this case green fuzzy stuff was an unintended resistance. Absolutely a learning curve. That is where you do a wire resistance test with an ohm meter. Thanks for sharing!

@ScannerDanner 6 лет назад

The ohmmeter will fail you in so many circumstance like this. It just doesn't stress the circuit enough and will show you false no resistance readings

@@ScannerDanner Awesome. Thanks for the reply. Hope you get a chance to give your feedback. I performed a loaded relay test (just like you did) and it checks out good (on a 2002 Dodge Durango with a PCM/TCM ). There's constant 12v+ at the relay (Pin 87) and 12v+ in the control wire (Pin 86) when I turn the key to ON position, while loaded my test light is bright. Ground connection is really good. Checked voltage and resistance through out the whole circuit. Also, I checked to make sure there's constant 12v at Transmission Solenoid Assembly connector during key cycle. The problem is after driving the truck for a few miles the code P0888 comes on. Prior to all my testing I replaced the Alternator because the voltage would drop below 12v if I rev'd up the engine's rpm during idle. I took the alternator to 2 different stores to get tested and it failed 4 times (2x at each store). Also, took the battery to get tested and that one checked out really good. Final thing I did, I jumped all the wires between the power dist box to the PCM/TCM and from PCM/TCM to the transmission to make sure there's absolutely no problems with the wiring. And the code still comes back on. Before I condemn the PCM/TCM is there anything else I should check? or does that pretty much confirm my PCM/TCM is malfunctioning after the engine compartment gets real hot? My apologies for this long question. :-(

Today you no longer have mechanic's. They are just parts changers. They check a code and start changing till they find what works yours is one of the first that does it right from the start. The only thing I would have done different is swapped relays withe the start or a/c to rule that out fist. But that's a trick us older mech learned when all this computer control came out.

That major elbow in the harness where the broken wires were found is a big problem area that can cause all sorts of issues. I noticed that TCM is also not long for this world. They rot out ALOT. I have replaced dozens and after seeing the condition of that one, was expecting to see no output from the module. Maybe next time lol. The dealer often has them in stock and they are not that expensive. They really thought that out sticking it in the wheel well loll. Good vid, thanks!

@psychofish7300 6 лет назад

If there have been several wires in the harness which have broken and needed repair, and you find one more which broke on its own, its time to replace the harness itself, not just the affected wires. Even if you fix the broken wire, and reattach the other previously repaired wires, another break will occur on another wire, and the cycle continues. The costs of replacing the wiring harness would have been less than 5 or 7 repair events, including an expert diagnostic job (for which cost does not apply toward the actual repair). This is a case of when the cheapest fix cost much more in the long run. Excellent information and troubleshooting walk through by ScannerDanner

@ScannerDanner 11 лет назад

Exactly. another way to think about it. 12v is feeding the bulb first then travels to the relay coil next. Part of the voltage drops across the bulb, the remainder across the coil. Coil resistance will determine bulb brightness in this series circuit. A low ohm coil = bright bulb, a high ohm coil =a dim bulb. Also the bulb itself is a factor too

Personally, I would try switching relays first just to make sure the relay's good. Then find which pin on the relay is for the switch rather than sending power thru the fuse/relay block and fry a circuit. Anyway, I don't do this kinda job but it's nice to know how to go about it and how it operates. Thanks for the video!

VERY old video but just saved me a bundle! Mine didnt shift gears, we wanted to take the box out to check, but it was a faulty relay.

your the best amigo my memory is not that great. but thank you for teaching all . God bless

Paul, it looks like all those wires should be checked. If the problem wire was bad without having been repaired before, what makes anyone think that others aren't about to do the same thing. Like you stated... How cool is it to be you not being the one to have to fix it... Great video.

Great job man, the whole load no load deal is just a life saver. Thanks for the help man. Keep it up. Straight from Az. "I wasnt a big fan of test lights", just when I thought that "power probe" was the most important tool in my arsenal

@Mr1Schoolmaster 5 лет назад

Testlight... The most valuable tool in my box.

@maxinpains6937 4 года назад

Test light for me as well . I always carrys cheapest $1 test light pen . Never have broke on me since I treasure it so much .

Scanner "The Man" Danner. Great video. That's some crappy old wiring when you can pull on it and it just breaks apart. Had no idea oxidation would do that. Makes me want to rewire my entire car, heat shrink, and seal every wire with high temp ceramic coating lol. Glad you get paid for this stuff. Great lesson thank you.

I have a 2009 and had the same problem with ours. I also went threw all the Electrical. What I ended up trying was adding additional Transition Fluid. The problem went away. I have now marked my dipstick at the level it took for the transition to work normal. Our Jeep acted just like a transition that was about a Quart Low. So far our problem has not come back.

Good stuff. Paul I have had good results using liquid tape applied to a connection and then heat shrink. After heating the shrink tube the liquid tape seals the area quite well.

About 15 years ago I worked on a car that the brake light didn't work I spent 4 hours on it because I was using a digital multimeter and it was saying I had 12v. For some reason I grabbed a test light and found the problem in 5 minutes. The point of this is there is a time for a multimeter and there is a time for a test light Great vid

thanks for your help, I learned quite a bit from your video

@Thor7167 11 лет назад

I agree with Scannerdanner! Just continue to follow him, buy his e-book (and read it), and practice on a lot of cars with no problems.

@rpdenney 10 лет назад

Great video. I am experiencing something similar with my 2003 Sebring Conv. Thank you!

@SchrodingersBox 9 лет назад

Amazing... The no-load test result of 12V would have thrown me off for sure! Total lesson learned to test circuits under load. I would love to know what ignorant knucklehead parts changers would thumbs down this video. I have to think that because it didn't show a transmission swap in 5 minutes or less they thumbs downed when they realized nothing more than voltage checks will be done.

@ScannerDannerPremium 9 лет назад

Thanks Matt. I think some people just want the fix to be shown without testing procedures and methods. What some do not realize is how much information I pack into each case study, maybe to a fault sometimes. But those that really want to learn this stuff truly appreciate it. So I don't worry about the thumbs down anymore. Happy New year friend

@SchrodingersBox 9 лет назад

ScannerDanner Premium You are correct at that sir- about people just wanting to see the fix. I think my all-time favorite comment on my channel was on a misfire diagnosis series where I basically covered just about every single possible variable you might have for a misfire and how to test each and every component to rule them out or confirm them as the problem. A guy commented he saw the series and thanked me for finally "setting him straight" because he previously changed almost every part in his car and the video "finally gave him an entirely new direction he never thought of" and he was confident he would finally fix his misfire. I was feeling pretty satisfied about converting a swaptron until 2 days later he says "I changed every single part you mentioned in your video series and still have the misfire- got any other videos with other ideas for parts I can try changing?" Sigh. You're right- those that want to learn, will. And those who don't will never understand what channels like these actually offer.All I can say is I have learned more from you in the past year than I have cumulatively in my whole life, and many things I have learned from you have literally been life changing for me- I mean, literally.. life changing. Happy New Year my friend.

@trainer2018 11 лет назад

Good explanation of voltage drop Paul, I liked the part where you show the unloaded voltage vs the loaded voltage, when you see voltage unloaded and very little with the circuit loaded, instant indicator you have corrosion in the circuit and you need to look for green wires. Two thumbs up.

I have got the relay test adaptors was the best money I have spent. pulls comes with adaptors to hook up test light and or malti meter as well. :-)

@jameschesnut3501 5 лет назад

I have a 02 pt cruiser. The transmission works good for about 5 miles then it completely stops. Let it set n cool off n does the same thing again. Any suggestions on what to check or do??

@larrymencke8632 8 лет назад

voltage drop testing and loaded circuit is key my dodge caravan had the same identical problem after diagnosing it mine was a bad selonoid shift pack a 225.00 part but well worth it the crystler garage told me they usally go out at 100k miles replaced mine at 98k miles and now at 211k miles on it still shifts like new very good lerning information videos thankyou great job
