ORC, CALIBRATION MISMATCH - ACTIVE ÐContinued
Page 105 of 4284

When Monitored and Set Condition:
ORC, CALIBRATION MISMATCH - STORED
When Monitored: With ignition on, the ORC monitors the PCI Bus for the VIN message
containing the body style. The PCM transmits the 17- character VIN message every 14
seconds. Note: The VIN message should match the vehicle VIN plate.
Set Condition: If the Body style stored in ORC does not exactly match the vehicle body
style indicated by the PCM, then the fault shall be set.
ORC, CLUSTER MESSAGE MISMATCH - STORED
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.
ORC, DRIVER SBS OPEN - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for an open condition.
Set Condition: The code will set if the ORC does not detect the correct circuit voltage.
ORC, DRIVER SBS SHORT TO BATTERY - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for an short to battery.
Set Condition: The code will set if the ORC detects high circuit voltage.
ORC, DRIVER SBS SHORT TO GROUND - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for a shorted together
or shorted to ground condition.
Set Condition: The code will set if the ORC detects low circuit voltage.
ORC, DRIVER SBT CIRCUIT OPEN - STORED
When Monitored: When the ignition is On, the ORC monitors the resistance of the Driver
Seat Belt Tensioner circuits.
Set Condition: The ORC has detected an open circuit or high resistance on the Driver
Seat Belt Tensioner circuits.
ORC, DRIVER SBT CIRCUIT SHORT - STORED
When Monitored: When the ignition is on, the ORC monitors the resistance of the Driver
Seat Belt Tensioner circuits.
