• Ignition off, wait for 15 seconds.
• Disconnect the connector for Supplemental restraint system module (SRS).
• Disconnect the connector from the driver's adaptive seat belt force limiter.

  HINT: Check if other diagnostic trouble codes (DTCs), that indicate another activatable collision protection system, are stored. 

  HINT: The fault is due to a short-circuit to another circuit in the activatable collision protection system. 

  Check connectors for damage to pins and connections.

  Also check other connectors and terminals that connect the wiring between the Supplemental restraint system module (SRS) and the seat belt tensioner.

  NOTE:

  The connector to the activatable collision protection system in the other circuit must be disconnected before a reading is taken.

  Check the cable. Check for a short-circuit to another circuit with activatable collision protection system. The resistance reading should read infinite resistance.

  Take readings between:

  • The connector to the driver's adaptive seat belt force limiter terminal #1 and the connector to the other activatable collision protection system terminals #1 and #2.
  • The connector to the driver's adaptive seat belt force limiter terminal #2 and the connector to the other activatable collision protection system terminals #1 and #2.

  Remedy as necessary.
