Test Description

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. 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.

4: This step tests to see if the malfunction is caused by the I/P module.
6: This step tests to see what DTCs are present. If DTC B0016 is present, test for a short between the I/P module high and low circuits. If DTC B0017 is present, test the I/P module high and low circuits for an open and for high resistance. If DTC B0018 is present, test the I/P module high and low circuits for a short to ground and for a short to voltage.

DTC B0016, B0017, or B0018

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 I/P module connector. Refer to Inflatable Restraint Instrument Panel Module Replacement . Inspect the component and harness sides of the I/P module 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 connector exhibit any signs of damage or corrosion?	Go to Step 3	Go to Step 4
3	If the component side of the I/P module connector is damaged, the I/P module must be replaced. Refer to Inflatable Restraint Instrument Panel Module Replacement . If the wiring harness side of the I/P module 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	Install the J 38715-A SIR Driver/Passenger Load Tool to the harness side of the I/P module connector. See Special Tools and Equipment . Use PASSENGER INFLATOR connector. Turn ON the ignition, with the engine OFF. With the scan tool, request the SIR DTC display. Does the scan tool indicate that DTC B0016, B0017, or B0018 are current?	Go to Step 5	Go to Step 7
5	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 I/P module 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 6
6	If DTC B0016 is present, test for a short between the I/P module high and low circuits. If DTC B0017 is present, test the I/P module high and low circuits for an open or high resistance. If DTC B0018 is present, test the I/P module high and low circuits for a short to ground or 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
7	Turn OFF the ignition. Replace the I/P module. Refer to Inflatable Restraint Instrument Panel Module Replacement . Did you complete the replacement?	Go to Step 9	-
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
