What does this fault code mean?
The SRS module checks the direct current in the stage 3 driver airbag circuit. Voltage above the limit for too long points to a short to supply voltage in that circuit.
Possible causes
- Wire shorted to the vehicle's supply voltage
- Short-circuit between the connections
What you can do
- 1Read and clear the code, drive the car and see whether it returns
- 2Have a workshop check the wire and connectors to the stage 3 airbag for a short to supply voltage
- 3If the wire has no fault, have a workshop replace the stage 3 driver airbag
- 4Do not carry out your own fault-finding on the airbag system; a workshop handles it
Symptoms you may notice1
- A red warning symbol and text message shown in the display
