orthotech28 Posted April 11, 2023 Report Share Posted April 11, 2023 I have. 2018 journey gt, 54k miles and I'm getting odd codes on my scanner. I only noticed them due to another cel for Throttle body ( which I fixed). No other cel, nothing changed in drivability or anything acting unusual with any other systems. U0010-00 can bus interior B2860-15 for ambient light short C121c-00 torque request denied B1a11-00 remote battery low C1504-96 tire pressure senor ( all four of them If my car was throwing just a couple codes I would say are real, but this many with a canbus code am I looking at a more complicated issue here? Tpsm on dash works just fine even tested it. None of these codes come up when I look at dtc codes thru the obd2 option. It's not until I use autodetect do these codes come up. I'm using launch 123e diagnostic reader. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted April 16, 2023 Report Share Posted April 16, 2023 Remote battery is the 3volt lithium battery, one in each remote. Can test with a multi meter, 5 yrs is longer than they usually last IMO. New they are 3.3 volts, some cars they will work at even less than 3 volts. The tire sensors also have lithium battery, that can’t be replaced, only whole sensor. Battery voltage often drops with temperatures, could have been triggered this winter. Can bus is very sensitive and phantom codes can turn up, could just clear them and see if they return. During start up on a cold day main 12 volt battery voltage also drops a lot when cranking, could have also caused codes. Quote Link to comment Share on other sites More sharing options...
