Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Refer to SIR Service Precautions .
When removing the connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:
  • Pretensioner
  • Inflatable restraint module
  • SDM module
  • Inflatable restraint module wiring harness connector
  • SDM wiring harness connector

The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly.
  1. Verify that the appropriate inflator restraint module connector and CPA are engaged.
    • If the above condition is not found, make the appropriate repair.
  2. Ignition OFF, disconnect the harness connector at the appropriate inflatable restraint module.
  3. With the appropriate load tool adaptor, connect special tool J 38715-A  in place of the inflator restraint module. See Special Tools .
  4. Ignition ON, with a scan tool, verify the appropriate DTC is set as current.
    • If the DTC is not set or is set as history, cycle ignition OFF, disconnect the adapter and J 38715-A  , reconnect the harness connector at the inflator restraint module, and cycle the ignition ON. See Special Tools . If the DTC resets after reconnecting the module, replace the inflator restraint module.
  5. Ignition OFF, disconnect special tool J 38715-A  and the adaptor. See Special Tools .
  6. Disconnect the harness connector at the SDM.
  7. Ignition ON, test for less than 1 volt between the appropriate high control circuit listed below and ground:
    • I/P module Stage 1 terminal 18
    • I/P module Stage 2 terminal 13
    • Left roof rail module terminal 9
    • Right roof rail module terminal 10
    • Left seatbelt pretensioner terminal 56
    • Right seatbelt pretensioner terminal 52
    • If greater than the specified value, test the high control circuit for a short to voltage.
  8. Test for less than 1 volt between the appropriate low control circuit terminal listed below and ground:
    • I/P module Stage 1 terminal 19
    • I/P module Stage 2 terminal 12
    • Left roof rail module terminal 8
    • Right roof rail module terminal 11
    • Left seatbelt pretensioner terminal 57
    • Right seatbelt pretensioner terminal 53
    • If greater than the specified value, test the low control circuit for a short to voltage.
  9. Ignition OFF, test for infinite resistance between the appropriate high control circuit terminal listed below and ground:
    • I/P module Stage 1 terminal 18
    • I/P module Stage 2 terminal 13
    • Left roof rail module terminal 9
    • Right roof rail module terminal 10
    • Left seatbelt pretensioner terminal 56
    • Right seatbelt pretensioner terminal 52
    • If not the specified value, test the high control circuit for a short to ground.
  10. Test for infinite resistance between the appropriate low control circuit terminal listed below and ground:
    • I/P module Stage 1 terminal 19
    • I/P module Stage 2 terminal 12
    • Left roof rail module terminal 8
    • Right roof rail module terminal 11
    • Left seatbelt pretensioner terminal 57
    • Right seatbelt pretensioner terminal 53
    • If not the specified value, test the low control circuit for a short to ground.
  11. Test for less than 1 ohm between the following high control circuit terminals listed below:
    • I/P module Stage 1 terminal A X1 and SDM terminal 18
    • I/P module Stage 2 terminal B X2 and SDM terminal 13
    • Left roof rail module terminal A and SDM terminal 9
    • Right roof rail module terminal A and SDM terminal 10
    • Left seatbelt pretensioner terminal 2 and SDM terminal 56
    • Right seatbelt pretensioner terminal 2 and SDM terminal 52
    • If greater than the specified range, test the high control circuit for an open/high resistance.
  12. Test for less than 1 ohm between the following low control circuit terminals listed below:
    • I/P module Stage 1 terminal B X1 and SDM terminal 19
    • I/P module Stage 2 terminal A X2 and SDM terminal 12
    • Left roof rail module terminal B and SDM terminal 8
    • Right roof rail module terminal B and SDM terminal 11
    • Left seatbelt pretensioner terminal 1 and SDM terminal 57
    • Right seatbelt pretensioner terminal 1 and SDM terminal 53
    • If greater than the specified range, test the low control circuit for an open/high resistance.
  13. If all circuits test normal, replace the SDM.
