Circuit/System Description

The Wait to Start lamp is located on the instrument panel cluster (IPC). The lamp informs the driver when to start the engine. The engine control module (ECM) monitors the lamp control circuit for conditions that are incorrect for the commanded state of the lamp. For example, a failure condition exists if the ECM detects low voltage when the lamp is commanded OFF, or high voltage when the lamp is commanded ON.
