CHECK CONNECTORS
NOTE :
Diagnose and repair all active codes before diagnosing stored codes (See Restraints Control Module DTC List in
Section 14 Restraints).
• With the scan tool, record and erase all RCM DTCs.
• Using the electrical schematic as a guide, inspect the following:
− Inspect the wiring and connectors of the related airbag system.
− Look for any chafed, pierced, pinched, or partially broken wires.
− Look for broken, bent, pushed out or corroded terminals.
− Verify that there is good pin to terminal contact in the related connectors.
Were any problems found?
Yes
>>
Repair as necessary.
No

CHECK DTC
• Reconnect all disconnected components and harness connectors.
• With the X-431 scan tool, read RCM DTCs.
• Refer to ⬙DTC Confirmation Procedure⬙.
Is DTC B1346 still present?
Yes
>>
Replace the RCM.
No
>>
The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
