What does this fault code mean?
The fault applies to the center second-row seat belt pretensioner. The airbag control module measures the resistance in the circuit and stores the code when it is too low. The causes are poor contact in the connector, short-circuited wires or connections, or a short circuit in the pretensioner itself.
Possible causes
- Poor contact in the seat belt pretensioner connector.
- The wires are short-circuited.
- Short circuit in the connections.
- Short circuit in the center second-row pretensioner, in its igniter part.
What you can do
- 1Read out the fault code and clear it. If it comes back, the fault is still present.
- 2Have a workshop check the connector to the center pretensioner for looseness and oxidation.
- 3Have a workshop check the wire for short circuits to other wires in the circuit.
- 4If the fault is still present once the wiring has been checked, have a workshop replace the center second-row pretensioner.
- 5Do not work on seat belt pretensioners or the airbag system yourself; have a workshop carry out the checks.
