Help!

Is there a way to test this sensor on the ground cable to see if it’s working? Trying to troubleshoot a “no connection to ECU” problem

I can connect through the OBD2 port getting a S0392 “no communication possible with: engine electronics “ code. Trying to cover all bases

The S codes are just tester faults, not a hard fault in the car. Try cycling the key off then back on, then read out the DME again. The car wouldn't run if the DME was actually not responding.

Car isn’t running. My kid was driving and had it stall and wouldn’t restart. Got an ignition fault on the dash and dsc light/fault as well.

Are there other faults stored for communication?
