The B0088 code indicates a fault in the control circuit for the third‑row right seat‑belt load limiter deployment. It signals that the vehicle's restraint system cannot verify proper operation of that specific load limiter.
The dedicated load limiter control unit or its internal sensor may have failed, preventing proper signal to the restraint system.
Corroded, damaged, or loose wiring and connectors in the third‑row right seat‑belt circuit can interrupt the load limiter signal.
A malfunction in the seat‑position or occupancy sensor for the third‑row right seat can cause the system to misinterpret load limiter status.
The module that processes seat‑belt signals may have a fault, though this is less common than component or wiring problems.
Occasionally a software glitch in the restraint system can trigger the code, requiring a re‑learn or update procedure.
No. The code relates to the seat‑belt load limiter circuit, which is managed by the restraint control module, not the power‑train control module (PCM). Replacing the PCM will not resolve this issue.
It is not advisable. The code indicates a fault that could prevent the load limiter from deploying correctly in a crash, potentially reducing occupant protection.
Most repairs involve inspecting or resealing wiring and connectors, which can be completed in one to two hours. Replacing a faulty load limiter module may require additional time for part removal and calibration.
