Symptoms

Owners of 2021-2025 Jeep Compass vehicles may experience an "Air Bag Module Sets Left or Right Rear Seatbelt Buckle Pretensioner Faults" message. This indicates a potential issue with the vehicle's occupant restraint system. This condition typically triggers a warning light on the instrument cluster, alerting the driver to a problem with the airbag system or seatbelt pretensioners.

Fault Codes / DTCs

When diagnosing the 2021-2025 Jeep Compass rear seatbelt pretensioner fault, technicians may observe specific Diagnostic Trouble Codes (DTCs) related to the left or right rear seat pretensioners. These codes indicate various electrical circuit issues within the seatbelt buckle pretensioner system.

Diagnosis and Trigger Conditions

This technical service bulletin, S2408000077, highlights a specific diagnostic anomaly within the Occupant Restraint Controller (ORC) Module Diagnostics software. The software relating to the 2nd Row Seatbelt Buckle Pretensioner DTCs has been found to incorrectly link and set a DTC for the opposite side of the vehicle where the actual fault is present. For example, if the ORC reports a DTC for the left side, the actual issue might be on the right side, and vice-versa. This means a technician using a diagnostic tool like wiTECH might initially see a code for one side, but the actual problem lies on the other.

Repair Procedure Summary

Due to the diagnostic software anomaly, when servicing any of the listed DTCs related to the 2nd Row Seatbelt Buckle Pretensioner, technicians are advised to view and service the opposite side from what the diagnostic tool initially displays. This ensures that the correct seatbelt pretensioner is addressed for the fault. For instance, if the ORC reports a DTC for the left side, the technician should follow the wiTECH diagnostic procedure for the right side. Conversely, if a DTC is reported for the right side, the diagnostic procedure for the left side should be followed. This approach is crucial for accurately resolving the 2021-2025 Jeep Compass rear seatbelt pretensioner fault.
