Warning Lamp Circuit Open

NOTE: This code becomes active and stored as soon as the malfunction is detected.

WHEN MONITORED: With the ignition on, the ACM sends a message to the cluster to turn the lamp on because of a detection of a malfunction, or during a lamp check.

SET CONDITION: With voltage and current on, the air bag warning lamp driver circuit (internal to the cluster) is other than expected.

POSSIBLE CAUSES:
- Faulty warning lamp
- Faulty cluster printed circuit board
- Faulty instrument cluster
