SRS light remains on after starting (engine) Why?

When the airbag light (SRS) is on or blinks it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called the clock spring contact, a coiled up ribbon electrical contact that turns with the steering wheel while maintaining a mechanical connection to the airgag mounted on the steering wheel, to replace this part you must disarm the airbag system and remove the steering wheel, this requires a special steering wheel puller tool and that you disarm the airbag system before you start the work, to do this disconnect the battery negative cable for 1 hour prior.

Here's a quick check list for most common cost of SRS / Air bag problem.


Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat

(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT disconnecting the negative battery connector to clean the code(s)

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.
