U1414

U1414-IMPLAUSIBLE/MISSING ECU CONFIGURATION DATA

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


When powered, the Occupant Restraint Controller (ORC) performs an internal self test. The repair of this fault does not involve any external circuitry and centers on verifying the module is configured correctly for the vehicle's restraint system components.


- When Monitored:
The ORC listens for a configuration message from the Totally Integrated Power Module (TIPM) starting 12 seconds after power up and then is monitored continuously.

- Set Condition:
When configuration message is not equal to programmed message or is missing this DTC will set. Once set it is latched for a power cycle. Mature time is equal to 4 seconds.







Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.Restraints System Pre-Diagnostic Procedure.


Diagnostic Test


1. DETERMINE ACTIVE OR STORED DTC
Is the DTC active or stored?

ORC - ACTIVE DTC


- Go To 2


ORC - STORED DTC


- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.Restraints System Intermittent Test.


2. REPLACE THE TOTALLY INTEGRATED POWER MODULE (TIPM)
Replace the Totally Integrated Power Module (TIPM).
Connect the scan tool to the Data Link Connector - use the most current software available.
Use the scan tool and erase all codes in the ORC.

NOTE: The ORC Reset Function must be performed after the repair to force the module to retest for this DTC. Access the Miscellaneous Function menu from the ORC ECU Overview screen on the scan tool to perform this operation.

Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
Wait one minute, and read active codes.
Does the U1414-Implausible/Missing ECU Configuration Data DTC return?

Yes

WARNING: 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.


WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
