For a complete wiring diagram Refer to Section 8W.When Monitored:While the CAN bus ignition status is IGN_RUN.Set Condition:This DTC will set if the ORC is not configured for Occupant Classification Module and the OCM is active on the CAN Bus. Note: Because all ORCs are originally configured for the OCM the ORC must learn the not equipped with OCM state from the TIPM.Possible CausesLOSS OF COMMUNICATION BETWEEN ORC AND TIPMMISSING CAN BUS CONFIGURATION MESSAGECORRUPT CONFIGURATION MESSAGEOCCUPANT RESTRAINT CONTROLLER (ORC)1.

CHECKING FOR CORRUPT CONFIGURATION MESSAGEWith the scan tool, read Occupant Restraints Controller (ORC) DTC.Does the scan tool display an active: U1414-IMPLAUSIBLE/MISSING ECU NETWORK CONFIGURATION DATA DTC?Yes Perform the U1414-IMPLAUSIBLE/MISSING ECU NETWORK CONFIGURATION DATA diagnostic test.No Go To 33. CHECKING FOR LOSS OF CAN BUS CONFIGURATION MESSAGEWith the scan tool, read Occupant Restraints Controller (ORC) DTCDoes the scan tool display an active U1415-IMPLAUSIBLE/MISSING VEHICLE CONFIGURATION DATA DTC?Yes Perform the U1415-IMPLAUSIBLE/MISSING VEHICLE CONFIGURATION DATA diagnostic test. No Go To 44. CHECKING FOR LOSS OF COMMUNICATION WITH THE TIPMWith the scan tool, read Occupant Restraints Controller (ORC) DTC.Does the scan tool display an active: U0141-LOST COMMUNICATION WITH FRONT CONTROL MODULE (TOTALLY INTEGRATED POWER MODULE)?Yes Perform the U0141-LOST COMMUNICATION WITH FRONT CONTROL MODULE(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING) No Go To 65. VERIFYING STORED B1BAA-OCCUPANT CLASSIFICATION MODULE CONFIGURATION MISMATCH DTCWith the scan tool, record and erase all DTC from the Occupant Restraint Controller.Turn the ignition off, and wait 15 seconds, then turn the ignition on.Wait one minute, and read active and stored codes.Does the scan tool display an active or stored B1BAA-OCCUPANT CLASSIFICATION MODULE CONFIGURATION MISMATCH DTC?Yes For active DTC-Go To 2Yes For stored-Go To 6No Perform *OCM SYSTEM VERIFICATION TEST. 6. REPLACE THE ORCTo avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.When reconnecting airbag system components the Ignition must be turned off and the Battery must be disconnected.RepairReplace the ORC in accordance with the Service Information.Perform *OCM SYSTEM VERIFICATION TEST.
