What it means

The airbag control module (SRS) has detected a fault in the deployment (squib) circuit for stage 2 of the driver frontal airbag, the stage normally used in more severe crashes. The code points to an open, a short or a resistance out of range. The airbag light comes on, and the airbag may not work as designed in a crash.

Symptoms4

Airbag light on.
Airbag system warning message.
The stage 1 code may appear too if the cause is shared, such as the clock spring.
Driving is not affected, but driver protection in a crash may be reduced.

Possible causes5

Damaged stage 2 track inside the clock spring (spiral cable) behind the steering wheel.
Loose or corroded stage 2 connector at the driver airbag or at system connectors under the dash.
Wiring damaged after steering wheel removal or accessory installation nearby.
Faulty driver airbag module.
Faulty airbag control module (SRS).

How to diagnose5

The technician reads the airbag module codes and checks whether the stage 1 code is also present.
If both stage codes are present, a shared cause such as the clock spring or a main connector is most likely.
If only the stage 2 code is present, testing focuses on that stage's path, its connector and the airbag module.
With the battery disconnected and the specified wait time, inspects connectors and wiring and follows the manufacturer's approved test procedure.
Do not unplug or test any airbag system connector yourself, since the airbag could deploy suddenly and cause injury.

How to fix6

Repairs must be done by a qualified technician with the battery disconnected per the manufacturer procedure.
Reseat or repair the stage 2 connector.
Repair damaged wiring using the approved method for airbag circuits.
Replace the clock spring if its stage 2 track is proven damaged.
Replace the driver airbag module or the airbag control module if proven faulty.
Clear the codes and confirm the airbag light goes out after start-up.

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low for a connector, rises with a clock spring, and reaches the upper end if the driver airbag or airbag control module must be replaced.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions

Why did the stage 2 code appear without stage 1?

Each stage has its own circuit and connector, so only one path may be damaged. When both codes appear together, a shared cause such as the clock spring is more likely.

Will the airbag still work if stage 1 is fine?

You cannot count on it. The system is designed to work as a whole, and any circuit fault may change or prevent deployment, so repair it soon.

This guide is for information only and does not replace an inspection by a qualified technician. If the fault involves brakes, steering, engine temperature, electrics or refrigerant, do not attempt the repair yourself.
