SYMPTOM
PANEL DIMMER OPEN

WHEN MONITORED
When the ignition is ON.

SET CONDITION
The Instrument Cluster monitors the panel lamps dimmer signal circuit for a resistance value between 0.0 ohms and approximately 3,650 ohms. When the cluster senses a value greater than 30,000 ohms for more than 5 seconds, this code will set. When this condition occurs, the cluster illumination will default to full brightness.

POSSIBLE CAUSES
- Panel dimmer open - intermittent condition
- Panel lamps dimmer signal circuit short to voltage
- Panel lamps dimmer signal circuit open
- Panel lamps dimmer switch open
- Panel lamps dimmer ground circuit open
- Instrument cluster
