Severity Level 4 — Serious
This code indicates a serious issue that can cause noticeable driveability problems and potential engine damage if not addressed. The vehicle should be taken to a mechanic as soon as possible. Extended driving is not recommended.
Common Symptoms
- Airbag/SRS warning light on — airbags may be disabled
- Check Engine Light illuminated
- Seat belt pretensioner may not deploy in a collision
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Faulty airbag module — most common cause, test before replacing
- Damaged or corroded wiring/connector in the airbag/SRS (supplemental restraint) system circuit
- Blown fuse or faulty relay for the airbag/SRS (supplemental restraint) system
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($35-145 at shop, free at auto parts store for basic scan)
- Visually inspect the airbag/SRS (supplemental restraint) system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $50 diagnostic fee at shop)
- WARNING: Airbag/SRS system work should be performed by a qualified professional. Disconnect battery for 15+ minutes before any SRS work. Replace faulty component and clear SRS codes with professional tool ($388-623 at qualified shop)
- Replace airbag module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($100-2000)
- Check and replace any blown fuses in the airbag/SRS (supplemental restraint) system fuse circuit — if fuse blows again, there's still a short that needs to be found ($1-10 for fuses)
