Hi All,

1st post here and after some help. My parking sensors are all offline - the console button works with LED on/off and the scanner confirms the PDC module is working and the sensors are working - all inputs are updated as expected (speed, enabled etc). BUT they're not working.

Scanner brings up two codes which CANNOT be reset (not reset and come back) just unable to clear.

B1 299
B2 477

Both have a very unhelpful description of "Please refer to vehicle service manual"

Any ideas people ??

Thanks

David

 

the PDC sensors are triggered with 5 volts... perhaps you can use an Ohmmeter to troubleshoot... are all the sensors not working? check each one? could be the PDC module
