CHRYSLER VOYAGER 2001 Service Manual

Symptom:
ORC, CLUSTER MESSAGE MISMATCH - ACTIVE
When Monitored and Set Condition:
ORC, CLUSTER MESSAGE MISMATCH - ACTIVE
When Monitored: After the MIC bulb test is completed, the ORC compares the Lamp
Request by ORC, On or Off, and the Lamp on by MIC, On or Off, PCI Bus messages. Each
message is transmitted one time per second or when a change in the lamp state occur.
Set Condition: If the Lamp Request by ORC, On or Off, and the Lamp on by MIC, On or
Off, messages do not match, the code will set.
POSSIBLE CAUSES
