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.
- 5:
This step tests to see if the malfunction is caused by the steering wheel module or by the steering wheel module coil.
- 7:
This step tests to see what DTCs are present. If DTC B0022 or B0042 is present, test the steering wheel module for a short between high and low circuits in stage 1 or stage 2. If DTC B0024 or B0043 is present, test the steering wheel module high and low circuits for an open and for high resistance in stage 1 or stage 2. If DTC B0026 or B0044 is present, test the steering wheel module high and low circuits for an open and for high resistance in stage 1 or stage 2.
DTC B0022, B0024, B0026, B0042, B0043, or B0044 (Buick)

- Turn OFF the ignition.
- Disconnect the steering wheel module coil in-line connector. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement .
- Inspect the component and harness sides of the in-line connector for the steering wheel module coil for damage or corrosion that may cause the malfunction. Refer to Testing for Intermittent Conditions and Poor Connections
and Connector Repairs
in Wiring Systems.
Does the connector exhibit any signs of damage or corrosion? |
Go to Step 3 |
Go to Step 4 |

- If the in-line connector for the steering wheel module coil is damaged, the steering wheel module coil must be replaced. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement .
- If the wiring harness side of steering wheel module coil in-line connector is damaged, replace the harness side of the connector. Refer to Connector Repairs
in Wiring Systems.

IMPORTANT:
When installing J 38715-A SIR Driver/Passenger Load Tool for testing the dual stage IP module, the correct 4-way load tool adapter connector must be used. Failure to use the correct 4-way load tool connector will set additional codes when testing.
- Use J 38715-80 adapter to connect the J 38715-A
SIR Driver/Passenger Load Tool to the harness side of the steering wheel module coil connector. See Special Tools and Equipment . Use BASE OF COLUMN and PASSENGER INFLATOR connectors.
- Turn ON the ignition, with the engine OFF.
- Use the scan tool to request SIR DTCs displayed.
Does the scan tool indicate that DTC B0022, B0024, B0026, B0042, B0043, or B0044 are current? |

- Turn OFF the ignition.
- Disconnect and remove both the J 38715-A
and adapter. See Special Tools and Equipment .
- Connect the steering wheel module coil in-line connector.
- Remove the steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Aztek) or Inflatable Restraint Steering Wheel Module Replacement (Rendezvous) .
- Use the J 38715-120 adapter to connect the J 38715-A
to the upper steering wheel module coil connector on top of the steering column. See Special Tools and Equipment . Use STEERING COLUMN and PASSENGER INFLATOR connectors.
- Turn ON the ignition, with the engine OFF.
- Use the scan tool to request SIR DTCs displayed.
Does the scan tool indicate that DTC B0022, B0024, B0026, B0042, B0043, or B0044 are current? |

- Turn OFF the ignition.
- Disconnect and remove both the J 38715-A
and adapter. See Special Tools and Equipment .
- Disconnect the inflatable restraint sensing and diagnostic module (SDM) connector. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement .
- Inspect the SDM connector for damage or corrosion that may cause a malfunction in the steering wheel module stage 1 or stage 2 high and/or low circuits. Refer to Testing for Intermittent Conditions and Poor Connections
and Connector Repairs
in Wiring Systems.
