This code indicates a malfunction in the deployment control circuit for the third-row center seat belt load limiter, which is part of the supplemental restraint system. The restraint control module has detected an open, short, or resistance fault in the circuit that controls the pyrotechnic load-limiting device. This typically prevents the system from verifying that the seat belt tensioner can deploy properly in a collision.
The pyrotechnic device integrated into the seat belt retractor or anchor point has developed internal resistance outside the specified range, or the squib has failed open.
Open circuits, shorts to ground, or chafing in the wiring running to the third row center seat belt, often caused by cargo contact, seat folding mechanisms, or abrasion against metal framework.
Loose terminals, moisture intrusion, or debris at the inline connector near the seat belt anchor point causing high resistance or intermittent connection.
The deployment circuit wires are making unintended contact with vehicle ground or battery voltage, causing the resistance check to fail or indicating deployment voltage where none should exist.
Internal malfunction of the SRS control module causing incorrect interpretation of circuit resistance, though this is statistically rare and should only be considered after wiring and component integrity are verified.
The vehicle will operate normally, but the supplemental restraint system may be disabled, meaning airbags and seat belt pretensioners might not deploy in a collision. Prompt diagnosis is recommended.
The load limiter is integrated into the seat belt assembly and is not serviceable separately; the complete seat belt assembly typically requires replacement if the pyrotechnic device is faulty.
Disconnecting the battery may temporarily extinguish the warning light, but the code will return immediately upon ignition if the circuit fault persists, as this indicates a hard electrical fault requiring physical repair.
No. This code concerns the restraint system and is monitored by the airbag control module (SRS module), not the engine computer. Replacing the PCM will not resolve this issue and represents an incorrect diagnosis.
