This code indicates a circuit malfunction in the deployment control for the second-row right seat belt pretensioner. The airbag control module has detected an open circuit, short to ground, or short to voltage that prevents proper operation of the pyrotechnic retractor. This fault will illuminate the supplemental restraint system (SRS) warning light and disable the affected pretensioner.
The pyrotechnic device inside the seat belt retractor has an internal open circuit, excessive resistance, or has been triggered, preventing the control module from verifying circuit integrity.
The circuit wiring between the pretensioner and airbag control module is open, pinched, chafed, or corroded, creating high resistance or a complete circuit break.
The electrical connector at the pretensioner or main harness junction has bent pins, terminal spread, moisture intrusion, or corrosion disrupting the deployment circuit.
Insulation damage has caused the wiring to short against the vehicle frame (ground) or another circuit (power), violating the isolated circuit requirements for deployment loops.
Internal malfunction of the SDM or ACM causing erroneous circuit monitoring, though this is statistically rare and should only be considered after wiring and component integrity are verified.
The vehicle will drive normally, but the supplemental restraint system is compromised. The specific pretensioner will not function in a collision, and the illuminated warning light indicates the airbag system may have additional disabled components.
No, this code indicates an electrical circuit fault (open, short, or resistance issue), not that deployment occurred. A deployed pretensioner typically shows physical evidence such as a locked or fully retracted seat belt and may set different diagnostic codes.
No. This code relates to the supplemental restraint system, which is controlled by the airbag control module (SDM/ACM), not the powertrain control module. Replacing the PCM will not resolve this issue; the fault almost always lies in the pretensioner itself or its associated wiring.
The pretensioner is typically integrated into the seat belt retractor assembly and is not serviceable as a standalone component. Replacement generally requires installing a complete seat belt assembly for that specific seating position.
