Pcm power relay

OBD II fault code P0685 is a generic code that is defined as “ECM/PCM power relay -circuit open”, and is set when the PCM (Powertrain Control Module) detects that its own power supply has failed, or if it detects a low voltage in the circuit that supplies it with power. Note that this code only applies to applications that use a relay to ....

Below are some reasons to set fault code P068A: – ECM/PCM power relay defect. – Incorrect use of relay. – Damaged wires and loose or rusty connectors. Open or short circuit issues. – A defective ignition switch. – A blown fuse. A bad charging system or battery can lead to abnormally high system voltages or very low system voltages.Get some tips to help diagnose a failed module quickly and accurately.
