Test Description

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. 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. 7:  This step tests to see if the malfunction is caused by the I/P module.
  2. 9:  This step tests to see what DTCs are present. If DTC B0016 is present, test the I/P module for a short between 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
  1. Turn OFF the ignition.
  2. Disconnect the I/P module in-line connector. Refer to SIR Disabling and Enabling Zone 5 .
  3. Inspect the component and harness sides of the I/P module in-line 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

  1. Install the J 38715-A  SIR Driver/Passenger Load Tool to the harness side of the I/P module in-line connector. See Special Tools and Equipment . Use the PASSENGER INFLATOR connector.
  2. Turn ON the ignition, with the engine OFF.
  3. 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 8  Go to Step 5 
5
  1. Disconnect and remove both the J 38715-A  and reconnect the in-line connector. See Special Tools and Equipment .
  2. Disconnect the I/P module pigtail connector. Refer to Inflatable Restraint Instrument Panel Module Replacement .
  3. Inspect the component and harness sides of the I/P module pigtail 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 6  Go to Step 7 
6
  1. If the module side of the I/P module pigtail connector is damaged, the I/P module must be replaced. Refer to Inflatable Restraint Instrument Panel Module Replacement .
  2. 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.

  1. 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 the PASSENGER INFLATOR connector with the X38775-110 adapter.
  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 DTC B0016, B0017, or B0018 are current?		 Go to Step 8  Go to Step 10 
8
  1. Turn OFF the ignition.
  2. Disconnect and remove both the J 38715-A  and adapter. See Special Tools and Equipment .
  3. Disconnect the inflatable restraint sensing and diagnostic module (SDM) connector. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement .
  4. 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 12  Go to Step 9

  1. If DTC B0016 is present, test the I/P module for a short between the high and low circuits.
  2. If DTC B0017 is present, test the I/P module high and low circuits for a short to ground and for a short to voltage.
  3. If DTC B0018 is present, test the I/P module high and low circuits for an open and for high resistance.
  4. All the above conditions refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 Go to Step 12  Go to Step 11 
10
  1. Turn OFF the ignition.
