Circuit/System Testing

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.
    IMPORTANT: When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector:
    • The pretensioner
    • The air bag module
    • The SDM module
    • The air bag wiring harness connector
    • The side impact module wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the applicable air bag module or pretensioner.
  2. With the applicable adaptor, connect J 38715-A 
  3. Ignition ON, with a scan tool, verify DTC is set as current.
    • If DTC is not set or is set as history, replace the applicable air bag module.
  4. Ignition OFF, disconnect J 38715-A  and the applicable adaptor.
  5. Disconnect the harness connector at the SDM.
  6. Ignition ON, test for less than 1-volt between the applicable HI circuit and ground.
    • If not the specified range, test the circuit for a short to voltage.
  7. Test for less than 1-volt between the applicable LOW circuit and ground.
    • If not the specified range, test the circuit for a short to voltage.
  8. Ignition OFF, test for infinite resistance between the applicable HI circuit and ground.
    • If not the specified range, test the circuit for a short to ground.
  9. Test for infinite resistance between the applicable LOW circuit and ground.
    • If not the specified range, test the circuit for a short to ground.
  10. Test for less then 1 ohm of resistance between the SDM connector and the air bag module connector HI circuit.
    • If not the specified range, test the circuit for an open/high resistance.
  11. Test for less then 1 ohm of resistance between the SDM connector and the air bag module connector LOW circuit.
    • If not the specified range, test the circuit for an open/high resistance.
  12. If all circuits test normal, replace the SDM.
