Ignition off
Disconnect the connector from the seat belt tensioner
Connect special tool 9511506 to the connector for the seat belt tensioner
WARNING:
Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected, non-deployed, pyrotechnical seat belt tensioner. This could deploy the seat belt tensioner

NOTE:
The special tool must be checked and fault-free. If the tool is defective, the diagnosis readings will be incorrect. This will make fault-tracing harder.
Switch on the ignition. Wait 10 seconds.
Read off diagnostic trouble codes (DTCs).

Try a new seat belt tensioner if the diagnostic trouble code (DTC) changes status from a permanent to an intermittent fault.

Other information:
- To replace the seat belt tensioner, see Seat belts, replacing .
