Circuit Description

WARNING: This page is about a different car, the 2000 Pontiac Firebird, 2000 Chevrolet Corvette, and 2000 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

Vehicle operation is disabled if incorrect key or starting procedure is used. BCM confirms correct key resistor pellet and sends a password to PCM through serial data circuit. If password matches password stored in PCM, fuel will be enabled. If PCM does not receive password or BCM does not send it, PCM will set.

Conditions for setting DTC are: system has reached the fuel enable decision point and PCM is in Failed Enabled Mode due to loss of communications with BCM after system received the correct password earlier in ignition cycle.
