Test Description

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2:  Inspects the steering wheel module coil in-line connector.
  2. 5:  Tests for a malfunctioning steering wheel module.
  3. 7:  If DTC B0022 is present, test for a short between the steering wheel module high and steering wheel module low signal circuits. If DTC B0024 is present, test for a short to ground or voltage in the steering wheel module high and steering wheel module low signal circuits. If DTC B0026 is present, test for an open or high resistance in the steering wheel module high and steering wheel module low signal circuits.
DTC B0022, B0024, or B0026 (Pontiac)

Step Action Yes No
Schematic Reference: SIR Schematics 
1 Did you perform the Diagnostic System Check - SIR? Go to Step 2  Go to Diagnostic System Check - SIR 
2 
  1. Turn OFF the ignition.
  2. Disconnect the steering wheel module coil in-line connector located at the base of the steering column. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement .
  3. Inspect both halves of the connector for the following conditions:
    • Corrosion
    • Terminal damage
    • Poor connections/terminal tension
Do the connectors exhibit any signs of corrosion, terminal damage, or poor connections?		 Go to Step 3  Go to Step 4

  1. If the steering wheel module coil connector exhibits any of the above conditions, the coil must be replaced. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement .
  2. Replace the harness side of the steering wheel module coil in-line connector. Refer to Connector Repairs in Wiring Systems.
Did you complete the replacement?		 Go to Step 11  -
4
  1. Use the J 38715-100 adaptor to connect the J 38715-A  SIR Driver/Passenger Load Tool to the harness side of the steering wheel module coil in-line connector. See Special Tools and Equipment .
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, request the SIR DTC display.
Does the scan tool indicate that either DTC B0022, B0024, or B0026 is current?		 Go to Step 6  Go to Step 5 
5 
  1. Turn OFF the ignition.
  2. Disconnect the J 38715-A  and adaptor. See Special Tools and Equipment .
  3. Reconnect the steering wheel module coil in-line connector.
  4. Remove the steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Aztek)  or Inflatable Restraint Steering Wheel Module Replacement (Rendezvous) .
  5. Use the J 38715-30A adaptor to connect the J 38715-A  to the upper steering wheel module coil connector. See Special Tools and Equipment .
  6. Turn ON the ignition, with the engine OFF.
  7. With a scan tool, request the SIR DTC display.
Does the scan tool indicate that either DTC B0022, B0024, or B0026 is current?		 Go to Step 9  Go to Step 10 
6
  1. Turn OFF the ignition.
  2. Disconnect the J 38715-A  and adaptor. See Special Tools and Equipment .
  3. Disconnect the SDM connector. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement .
  4. Inspect the SDM connector for corrosion or damage. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 Go to Step 11  Go to Step 7 
7 
  1. If DTC B0022 is present, test the steering wheel module high and steering wheel module low signal circuits for a short. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  2. If DTC B0024 is present, test the steering wheel module high and steering wheel module low signal circuits for a short to ground or voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  3. If DTC B0026 is present, test the steering wheel module high and steering wheel module low signal circuits for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 Go to Step 11  Go to Step 8 
8 Replace the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement .
Did you complete the replacement?		 Go to Step 11  -
9 Replace the steering wheel module coil. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement .
Did you complete the replacement?		 Go to Step 11  -
10 Replace the steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Aztek)  or Inflatable Restraint Steering Wheel Module Replacement (Rendezvous) .
Did you complete the replacement?		 Go to Step 11  -
11
  1. Reconnect all SIR system components.
  2. Verify that all components, connectors and CPAs are properly mounted.
  3. Use the scan tool in order to clear the DTCs.
