Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

How to fix code B1802.
SRS Airbag light flash after removing the airbag.-
Thanks for the question. The B1802 code means there’s a short to ground in the driver-side squib circuit, which is part of the airbag wiring — usually the clockspring or the connector to the driver airbag itself.
Since you mentioned the light came on after removing the airbag, here’s what most likely happened:
Common causes:
- Airbag was reconnected with the battery still connected – this can instantly trigger the SRS light and set a code.
- Clockspring not reconnected properly or damaged while removing/reinstalling the airbag.
- Loose or improperly seated connector under the steering wheel — especially the yellow airbag connector.
- Wire pinched, grounded, or broken when putting the airbag back in.
How to fix:
- Disconnect the battery and wait at least 10 minutes before touching anything in the SRS system.
- Carefully remove the airbag again and inspect the connector — make sure it clicks in solid and no pins are bent or damaged.
- Check the clockspring harness behind the steering wheel — if it was twisted too far or damaged, it can short the circuit.
- Reconnect everything, then clear the SRS code with a scan tool that can talk to the airbag module.
- If it clears and doesn’t come back, you're good. If it returns right away, you may need to test the clockspring or wiring with a multimeter — but don’t use an ohmmeter directly on the airbag; use a known-safe procedure or airbag simulator if available.
Let me know if you want help checking the clockspring or need the exact wire colors to test. Happy to help.
