Water-in-Fuel Lamp Diagnosis

Ignition 1 voltage is supplied directly to the water in fuel lamp. The engine control module (ECM) turns the water in fuel lamp ON by sending a request to the instrument panel cluster via the CAN communication circuit. The ECM monitors the amount of water in the fuel with a sensor located in the fuel filter assembly. When the water in the fuel is above an acceptable level, the ECM sends a request to illuminate the water in fuel lamp.
