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 number below refers to the step number on the diagnostic table.

7: Tests to see what DTCs are present. If DTC B0028 s present, test the side impact module-RF for a short between high and low circuits. If DTC B0029 is present, test the side impact module-RF high and low circuits for an open and for high resistance. If DTC B0030 is present, test the side impact module-RF high and low circuits for a short to ground or a short to voltage.

DTC B0028, B0029, or B0030

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	Turn OFF the ignition. Disconnect the side impact module-RF connector. Refer to Inflatable Restraint Side Impact Module Replacement - RH . Inspect the component and harness sides of the side impact module-RF connector 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 side impact module - RF connector exhibit any signs of damage or corrosion?	Go to Step 3	Go to Step 4
3	If the component side of the side impact module-RF connector is damaged, the side impact module-RF must be replaced. Refer to Inflatable Restraint Side Impact Module Replacement - RH . If the harness side of side impact module-RF connector is damaged, replace the harness side of the connector. Refer to Connector Repairs in Wiring Systems. Did you complete the repair?	Go to Step 9	-
4	Connect the J 38715-A SIR Driver/Passenger Load Tool to the harness side of the side impact module-RF wiring harness connector. See Special Tools and Equipment . Use the PASSENGER INFLATOR connector. Turn ON the ignition, with the engine OFF. Use the scan tool to request SIR DTCs displayed. Does the scan tool indicate that DTC B0028, B0029, or B0030 are current?	Go to Step 6	Go to Step 5
5	Turn OFF the ignition. Disconnect and remove the J 38715-A . See Special Tools and Equipment . Replace the side impact module - RF. Refer to Inflatable Restraint Side Impact Module Replacement - RH Did you complete the replacement?	Go to Step 9	-
6	Turn OFF the ignition. Disconnect and remove the J 38715-A . 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 side impact module-RF high and/or low circuits. 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 9	Go to Step 7
7	If DTC B0028 is present, test the side impact module-RF high and low circuits for a short between the two circuits. If DTC B0029 is present, test the side impact module-RF high and low circuits for an open and for high resistance. If DTC B0030 is present, test the side impact module-RF high and low circuits for a short to ground and for a short to voltage. All the above conditions refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 9	Go to Step 8
8	Turn OFF the ignition. Replace the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement . Did you complete the replacement?	Go to Step 9	-
9	Connect all SIR components. Turn ON the ignition, with the engine OFF. Use the scan tool in order to clear the DTCs. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text. Does the DTC reset?	Go to Step 2	System OK
