Co oznacza ten kod błędu?
The fault is sub-fault A of the front passenger seat belt pretensioner. The airbag control module measures the resistance in the circuit and stores the code when the resistance is too low. The causes are poor contact in the connector, short-circuited wires or connections, or a short circuit in the pretensioner itself.
Możliwe przyczyny
- Poor contact in the seat belt pretensioner connector.
- The wires are short-circuited.
- Short circuit in the connections.
- Short circuit in the passenger seat belt pretensioner, in its igniter part.
Co możesz zrobić
- 1Read out the fault code and clear it. If it comes back, the fault is still present.
- 2Have a workshop check the connector and connections to the pretensioner for loose contact.
- 3Have a workshop check the wire to the pretensioner for a short circuit to other wires in the circuit.
- 4If the fault is still present once the wiring has been checked, have a workshop replace the passenger seat belt pretensioner.
- 5Do not work on seat belt pretensioners or the airbag system yourself; have a workshop carry out the checks.
