Circuit/System Description

The diesel particulate filter regeneration lamp is located on the instrument panel cluster (IPC). The lamp informs the driver when a diesel particulate filter service is required. 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.
