Deployment Inside Vehicle (Vehicle Scrapping Procedure)

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

Deploy the inflator modules inside of the vehicle when destroying the vehicle or when salvaging the vehicle for parts. This includes but is not limited to the following situations:

CAUTION: Refer to SIR Inflatable Module Deployment Outside Vehicle Caution .
  1. Place the ignition to the OFF position.
  2. Remove the ignition key.
  3. Put on safety glasses.
  4. Remove all loose objects from the front seats.
  5. Disable the SIR system. Refer to SIR Disabling and Enabling .

    CAUTION: A deployed dual stage inflator module will look the same whether one or both stages were used. Always assume a deployed dual stage inflator module has an active stage 2. Improper handling or servicing can activate the inflator module and cause personal injury.
  6. Disconnect the steering wheel module coil yellow connector (2) from the vehicle harness connector (6).
  7. Disconnect the I/P module connector (3) from the vehicle harness connector (1).
    8. IMPORTANT: This vehicle is equipped with dual stage air bags, the steering wheel module and I/P module will have 4 wires each. Refer to SIR Connector End Views  for determining high and low circuits.
  8. Cut both yellow harness connectors out of the vehicle, leaving at least 16 cm (6 in) of wire at the connector.
  9. Strip 13 mm (0.5 in) of insulation from each of the connector wire leads.
