The only active code is hood ajar and will replace the hood ajar switch/latch.
I have checked for water leaks on the BCM and everything is dry and looks good.
I have tested the battery and it’s good
I have with the engine started tried to trigger the error codes by wiggling the connectors/harness going to the BCM by the module, harness going to BCM from the ECU, Tapping the TIPM box and fuses, CAN distribution box under steering wheel.
No success
Any suggestions on to where to start troubleshooting?
Sorry for long text, dont know how to insert codes a better way.
