What does this fault code mean?
The control module stores this code when the resistance in the circuit to the center second-row seat belt pretensioner is too high. It can be caused by poor contact in the connector, a break in the wire, contact resistance or oxidation in the connections, or a break in the pretensioner itself.
Possible causes
- Poor contact in the seat belt pretensioner connector.
- Break in the wire.
- Contact resistance or oxidation in the connections.
- Break in the center second-row pretensioner, in its igniter part.
What you can do

- 2Have a workshop check the connector and connections to the center pretensioner for looseness and oxidation.
- 3Have a workshop check the wire to the pretensioner for a break.
- 4Have a workshop replace the center second-row pretensioner if the wire and connectors are intact.
- 5Do not work on seat belt pretensioners or the airbag system yourself; have a workshop carry out the checks.
