B336

BCM Code B336:

BCM Circuit:

CIRCUIT DESCRIPTION:
Code B336 will set if the ignition is "ON" and the BCM loses data communication with the IPC. The problem is a result of a system voltage power or ground fault to the IPC, or a double open circuit in the data communication line between the IPC and the BCM or a loss of +10 volt wake-up to the IPC. If this occurs, the cruise control will disengage (if "ON") and the headlamps (if "ON") will be on low beams.
