P1A8E CHEVROLET Description
The Auxiliary Power Module (APM) 12-volt output voltage is used for a 12-volt line APM output voltage control and a 12-volt line voltage sensor rationality check. The Starter/Generator Control Module (SGCM) monitors the voltage sensor for the following:
To detect the failure of the APM 12-volt voltage sensor circuit below valid range.
To detect the failure of the APM 12-volt voltage sensor circuit above valid range.
