Circuit/System Testing

WARNING: This page is about a different car, the 2008 Cadillac STS. 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 SDM wiring harness connector
  1. Ignition OFF, disconnect the harness connector at the applicable air bag module. Refer to the applicable air bag module replacement procedure.
  2. Ignition ON, test for less than 1 volt between the applicable high control circuit terminal and ground.
    • I/P Module - Stage 1 terminal 10
    • I/P Module - Stage 2 terminal 6
    • Left Front Roof Rail Module terminal 13
    • Right Front Roof Rail Module terminal 14
    • Seat Belt Pretensioner - Left terminal 25
    • Seat Belt Pretensioner - Right terminal 26
    • Side Impact Module - Left terminal 17
    • Side Impact Module - Right terminal 18
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the SDM.
  3. Test for less than 1 volt between the applicable low control circuit terminal and ground.
    • I/P Module - Stage 1 terminal 11
    • I/P Module - Stage 2 terminal 7
    • Left Front Roof Rail Module terminal 12
    • Right Front Roof Rail Module terminal 15
    • Seat Belt Pretensioner - Left terminal 24
    • Seat Belt Pretensioner - Right terminal 27
    • Side Impact Module - Left terminal 16
    • Side Impact Module - Right terminal 19
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the SDM.
  4. Ignition OFF, test for infinite resistance between the applicable high control circuit terminal and ground.
    • I/P Module - Stage 1 terminal 10
    • I/P Module - Stage 2 terminal 6
    • Left Front Roof Rail Module terminal 13
    • Right Front Roof Rail Module terminal 14
    • Seat Belt Pretensioner - Left terminal 25
    • Seat Belt Pretensioner - Right terminal 26
    • Side Impact Module - Left terminal 17
    • Side Impact Module - Right terminal 18
    • If not the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the SDM.
  5. Test for infinite resistance between the applicable low control circuit terminal and ground.
    • I/P Module - Stage 1 terminal 11
    • I/P Module - Stage 2 terminal 7
    • Left Front Roof Rail Module terminal 12
    • Right Front Roof Rail Module terminal 15
    • Seat Belt Pretensioner - Left terminal 24
    • Seat Belt Pretensioner - Right terminal 27
    • Side Impact Module - Left terminal 16
    • Side Impact Module - Right terminal 19
    • If not the specified value, test the circuit for a short to ground. If the circuit tests normal, replace the SDM.
  6. With the applicable adaptor, connect in place of the air bag module.
  7. Ignition ON, verify the DTC is set as current.
    • If DTC is not set or is set as history, replace the applicable air bag module.
  8. Ignition OFF, disconnect and the applicable adaptor.
  9. Disconnect the harness connector at the SDM.
  10. Test for less than 1 ohm of resistance between the following high control circuit terminals.
    • I/P Module - Stage 1 terminal 10
    • I/P Module - Stage 2 terminal 6
    • Left Front Roof Rail Module terminal 13
    • Right Front Roof Rail Module terminal 14
    • Seat Belt Pretensioner - Left terminal 25
    • Seat Belt Pretensioner - Right terminal 26
    • Side Impact Module - Left terminal 17
    • Side Impact Module - Right terminal 18
    • If not within the specified range, test the circuit for an open/high resistance.
  11. Test for less than 1 ohm of resistance between the following low control circuit terminals.
    • I/P Module - Stage 1 terminal 11
    • I/P Module - Stage 2 terminal 7
    • Left Front Roof Rail Module terminal 12
    • Right Front Roof Rail Module terminal 15
    • Seat Belt Pretensioner - Left terminal 24
    • Seat Belt Pretensioner - Right terminal 27
    • Side Impact Module - Left terminal 16
    • Side Impact Module - Right terminal 19
    • If not within the specified range, test the circuit for an open/high resistance.
  12. If all circuits test normal, replace the SDM.
