Fixing a vehicle with no TCM communication

[@johnnypalacios9920]

That was amazing. You actually took the time to use the technology that is available today and used it in the proper manner. By doing the proper research and getting to the root of the problem, you took all the guess work out of the equation, Saving the owner money, you made more money in less time. That is a win, win, if there ever was a win, win.

[@alnewell31]

Wow ! You are what an actual “Technician “ is supposed to be ! Unfortunately Most are just parts replacers, Nice run through process. You would be my go to guy for everything.

[@rubenmata9720]

Thanks! I was bracing my self for the $1200 TMC replacement I was told was most likely the reason I had tmc lost communication. I watched the video and just bought the relay on a prayer…just like that all was good!

[@rubenmata9720]

Sorry TCM transmission control module

[@Tha_Marine]

2-24-2024 the day OZ mechanics saved me some money tell me why i checked those diodes and it was backward my car was down for a year trying to figure it out my dude THANK YOU man seriously means alot .....

[@OzMechanics]

Dude this is awesome. I’m glad this video helped out. Thanks for watching

[@quincyneto7468]

This video saved me so much money!!! I was about to replace my whole TCM module.. Thanks for the information 👍

[@wyattstimatze530]

Thank you sir I thought my tcm was bad I did everything but check fuse because I didn’t think it had one. You literally just saved me 1200$ gave you thumps up and subscribed

[@OzMechanics]

Awesome to hear that brother. Thanks for watching

[@amr-50]

despite leaving the field i am still watching your videos and let me tell you you are one hell of an instructor , thanks for your videos

[@HoodRichSWERVE]

You are a wizard! I wish I could find someone as experienced and thorough as you to fix my wiring Can issue

[@HoodRichSWERVE]

Agree

[@GrindHard365]

Right

[@michealsandoval4251]

I couldn't figure this out as I never subscribed to anybody you are so awesome and cool dude I am truly impressed by your knowledge just had saved me so much time as soon as I get a little bit of cash on my card I will buy something off you thank you have a great day you're awesome

[@lupemaldonado3632]

Everytime I see your videos I just say to myself that guy's good. When you love what you do its all easy. You fixed my F150 about three weeks ago and I knew then you were the man. Keep making those videos and remember people gonna hate you cause they ain't you. God bless

[@gort400]

THANK YOU! Great Troubleshooting job. Good instructor too. I have a 96 Jeep Cherokee that will not go into any gear and move. It will shift out of park to R to N, D to 1-2 but no movement. I have a troubleshooting light and may just try to trace the TCM signal like you did here. Just to make sure I am getting the voltage. I have never used the trouble light but there is a first time for everything! Especially when you made it so clear.

[@spelunkerd]

Diodes can overheat and blow just like a fuse, which is probably why the are placed in a way that allows easy replacement. Unfortunately the little knob on the side didn't prevent if from being replaced backwards. I rarely find occasion to use the diode testing tab on my multimeter, but testing a diode is very easy, and you can even assess forward voltage drop. Excellent case study!

[@spelunkerd]

@@liviu2004 Yes, Zener diodes in particular have a breakdown voltage which makes them useful for overvoltage protection. If reverse voltage spikes too high, the diode allows a path to ground, which protects other more sensitive devices in the circuit from overvoltage. Like a fuse, it is hopefully positioned to fail at a spot that is hopefully easy to repair.

[@lorenzoparedes2306]

Also, one can use a LOW VOLTAGE ohmmeter to test the diode. It will show higher resistance when polarity is applied backwards. I capitalized the low voltage wording to prevent someone from frying an otherwise good diode while testing.

[@xuchun5371]

if bring to local mechanic may tell you need to change $ 1000's xyz modules along with $100's labor fee

[@chrisrowe9471]

I just want to say thank you from all us car guys ! Fixed my issue

[@talentscout5135]

Always good to look over fuses and see if you notice one out of line first also and often saves even more time but yeah great job going through the process for people is even better

[@gunna2177]

Thank you bro! I wasn’t getting any power to the 15a with the test light, went over to the relay and there wasn’t a black cover over it, so i changed the fuse and relay everything went back to normal nomore limp mode. I really appreciate you bro!

[@kenbkooln9289]

Hey man do you happen to be Dodge Charger owner? And we’re your fuses bad or not put in properly? I’m going through the limp mode thing. Car has been down 2 weeks and I miss my v8 😞

[@ferdelolmopersonal9100]

Justo estoy pasando por este problema, muchos mecánicos le han metido mano a mi mi auto y lo han dañado del sistema de enfriamiento y ahora perdió comunicación con la TCM. He testeado los fusibles y parecen tener conexión pero revisaré les relays y todo a mayor profundidad esperando resolver el problema. Muchas gracias por este gran video ha informado de mucho!

First of all. Your instruction was simple and amazing. You showed visual papers, steps with instruction etc. I need to check my TCM Relay for shifting issues. I notice a pattern with car of fuse and sensory blown out. I will check this out before anything else.

[@ManifestNMotivate369]

Your only person I've found that explains it and shows diagrams that makes sense to me. Thank you. This is going help me get my jeep shitbox fixed finally 😄

The "Tech" who installed the diode backwards thinks diodes are like fuses, which can be installed either way. Additionally, he has no power of observation for details, such as the keyed bump on the diode jacket, to indicate proper polarity insertion into the board. Thank you for the video.
