FCM, SIACM RUN-START DRIVER OPEN - ACTIVE ÐContinued

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
MIC, COMMUNICATION FAILURE
MIC, CLUSTER MESSAGE MISMATCH
ORC, CLUSTER MESSAGE MISMATCH

AIRBAG

Symptom:
ORC, NO CLUSTER MESSAGE - ACTIVE
When Monitored and Set Condition:
ORC, NO CLUSTER MESSAGE - ACTIVE
When Monitored: With the ignition in the On position, the ORC monitors the PCI Bus for
a message from the MIC containing the airbag warning lamp status. The MIC transmits
the message one time at ignition on, lamp state change, or in response to the ORC lamp
message.
Set Condition: If the MIC message is not received for 10 consecutive seconds, the code
will set.
POSSIBLE CAUSES
MIC, COMMUNICATION FAILURE
NO CLUSTER MESSAGES
