Hi everyone who can help error code is u0101 CAN comm error or TCM, car is Infiniti g25 2011 wont start, I check all fuses replace shift selector, car now don't have headlamps, acc is on but it wont start and don't show gears on dash like in video, show yellow key. Ans sorry for my english

 

Usually a solid yellow key light indicates a problem on the vehicle side, and it’s not cycling to off when you have the brake applied. The fob should be good. Check the steering column lock, that prevents the car from starting. You may also have an issue with the bcm. There’s plenty of other forums out there

 

Car detect key, brake stop signal button is ok, and check starter and starter relay its ok too, I don't know how to check BCM

 

From what I gather, the key is detected. If you can move the gear selector, then the brake switch should be fine. I’ve only had a UXXXX code come up when my car didn’t shut down one time, failed to communicate with HVAC or something. At this point I’d suspect BCU, but check fuses/relays and the like.

 

Yes you are right key detected, gear selector is moved, i try to check BCM module in few days

 

thank you for answer Conboss, I fix it in my car its corrosion in driver side can connector and check a/t fuse in fuse box behind battery

 

Glad to hear you found a fix! Maybe post a picture of the connector at fault for future members?
