Restraints Control Module Diagnostic Trouble Codes
AFFECTED VEHICLE RANGE:
CONDITION SUMMARY:
Situation:
The Restraints Control Module (RCM) may be found to have one or more of the following Diagnostic Trouble Codes (DTC):
^
B0070-1B: Driver seatbelt pretensioner deployment control resistance too high.
^
B0072-1B: Passenger seatbelt pretensioner deployment control resistance too high.
* ^
B1212-1B: Driver Seatbelt Buckle Pretensioner Deployment Control - circuit resistance above threshold
Driver seatbelt buckle pretensioner deployment control circuit open circuit high resistance.
^
B1213-1B. Passenger Seatbelt Buckle Pretensioner Deployment Control - circuit resistance above threshold
Passenger seatbelt buckle pretensioner deployment control circuit open circuit, high resistance.*
This may be caused by improper routing of the under-seat wiring harness of the seatbelt buckle pretensioner, causing a strain on the harness connectors
at the extremes of seat adjustment. The subsequent harness strain can lead to the DTC logs.
Action:
Should any of the above DTCs be present in the RCM or a new harness is being installed, refer to the Repair Procedures detailed in this bulletin to
correctly route and secure the wiring harness.
