2020 Chevy Trax, A/C not working , can bus configuration learn , what the

[@jameslowry3208]

This is EXACTLY what I ran across today! 20 Trax no A/C w ambient sensor codes, literally did everything you did and connector was unplugged under bumper. End of the day was then, I can't wait to go to work tomorrow and do the relearn! I offer you this virtual beer great sir. 🍺

@lakesautomotivediagnostics6509 took me 3 mins to plug bumper up and temp hang it and did procedure. All good!! Ty so much!!

Thanks for this vid. I bought a used Trax that had front end damage that had been repaired. The sensor was missing, and the wires were nowhere to be found. The car lot I bought it from (I assume) literally just cut the wires at that connector on the driver side of the car. Now I just need to splice some wires in and connect a sensor. I would have never found where these wires had been cut without your vid.

Nice catch bro....different functions are hard to find depending on the scan tool, so luckily it work out..

[@lakesautomotivediagnostics6509]

Yeah, I had a little wasted time but least I got it figured out

[@robertmedina6875]

Awesome video Brotha!! I am sure that will help all of us techs out here!!

[@lakesautomotivediagnostics6509]

It cost me a couple hours, definitely the first time I have seen that, thanks for watching. Hope you have a great day.

[@jerrikjordan2176]

I would of tested the connectors for power and signal. That would help you speed the process up next time. But I feel you tho bro. Some days it be like that.

Thank you! I'm subscribed to you. I need one to show why the radiator fan doesn't engage 😞

[@lakesautomotivediagnostics6509]

Thanks for the sub! There should be plenty of good videos on KZbin showing how to check to see why your fan is not working. It could be a relay a fuse. The fans could be bad also could be wiring.

Great job man...only a scan tool do this calibration can bus data?

[@lakesautomotivediagnostics6509]

Yes, that was the first time I have ever seen a can bus calibration. Thanks for watching

I had the same problem did all the steps you've done and is still don't blow cold, freon is in, compressor is running, high ac line is hot...what do you think it could be?

[@lakesautomotivediagnostics6509]

Did you evacuate the AC system and recharge with the correct amount?

Did you have any codes and what was your AC high and low pressure
