Circuit/System Description
The starter/generator control module (SGCM) monitors the heater core pump control circuit for an open wire or a over current condition.
The battery energy control module (BECM) monitors to detect if the cooling fan is enabled, in the stuck off position, or in the stuck on condition. If a failure is detected, the appropriate DTC will set.
The battery energy control module (BECM) monitors the cooling fan to detect if the fan speed is slower or faster than normal. If a failure is detected, the appropriate DTC will set.
