▸ SRS / AIRBAG WARNING

Airbag light on
after an accident?

After any collision — even a minor one — a lit SRS/airbag light usually means the airbag control module has stored a permanent crash (hard) code and locked itself, or a deployed component needs replacement and programming. It will not clear with a normal scan-tool erase. Spot-On diagnoses the fault, resets or replaces the SRS module, and clears crash data at our San Antonio shop.

▸ WHAT'S USUALLY HAPPENING

Common causes.

  • Crash data locked in the moduleAfter a deployment the SRS module writes permanent hard codes. Most cannot be cleared with a normal erase — the module is locked until it is reset or replaced.
  • Deployed or damaged componentsBlown airbags, seat-belt pretensioners, or impact/crash sensors have to be replaced before the warning will clear.
  • Disconnected or damaged wiringConnectors under the seats or in the harness are commonly pulled or pinched during collision repair, setting circuit faults.
  • Replacement module not codedA new or used SRS module has to be programmed and coded to your exact VIN before it will function.
▸ HOW SPOT-ON HANDLES IT

Diagnosed properly, fixed at the root.

The SRS system controls live pyrotechnic devices — clearing the light without fixing the cause can leave airbags that won’t fire in a crash, or that fire unexpectedly. This is why a proper crash-data reset and module coding require OEM tooling and cannot be done with a generic code eraser. It is a safety system, not a nuisance light.

  1. Read the hard codes. We pull the stored SRS codes and identify whether the module is reset-eligible or must be replaced.
  2. Reset or replace the module. Reset crash data where the module allows it, or install and VIN-program a replacement.
  3. Repair deployed components & wiring. Confirm airbags, pretensioners, sensors, and connectors are correct and intact.
  4. Verify system readiness. Clear codes, confirm no active faults, and check the airbag lamp completes its self-test.

▸ COMMON QUESTIONS

Questions we get about this.

Can you just turn off the airbag light?
Not safely. If there is a stored crash code or a deployed component, clearing the light without fixing the cause disables your crash protection. We diagnose and repair the actual fault first, then verify the system is live.
Do I need a new airbag module, or can it be reset?
It depends on the code. Some modules allow a crash-data reset; modules with deployment codes usually must be replaced and programmed to your VIN. We tell you which after diagnosis — no guessing.
My body shop finished the repair but the light is still on — can you help?
Yes. This is common. We handle post-collision SRS coding and any related ADAS recalibration. Body shops are trade partners, so we can also come to their bay to finish the electronics.
