P0af8 Gmc Description

The Engine Control Module (ECM) monitors the correlation of the generator battery disconnect control module battery voltage and the Starter Generator Control Module (SGCM) output voltage to detect a 36 volt cable open or fuse/relay failure. The ECM also monitors to detect an over voltage condition and protect the MOSFET (load dump). If either one of these conditions is detected, the appropriate Diagnostic Trouble Code (DTC) will set.
