Code P1EAB GMC Description
The 2nd protection self test diagnostic is used to check the signal circuit. The hybrid/EV battery energy control module performs this test, once, every power down cycle. When run/crank input signal transitions low and after a calibrated delay, the hybrid/EV battery energy control module informs the hybrid/EV powertrain control module 2, via serial data communication bus that it is about to run the diagnostics on the 2nd protection circuit. The hybrid/EV battery energy control module then proceeds to command, via internal serial data, each hybrid/EV battery interface control module to run the check on its hardwire output. Each of the four hybrid/EV battery interface control modules pulls the signal circuit low and releases it, in sequence. If any pulses are missing, the hybrid/EV battery energy control module is able to diagnose which hybrid/EV battery interface control module(s) has a fault and sets a related fault and sends this information to the hybrid/EV powertrain control module 2 on the serial data
