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. 4:  This step tests to see if the malfunction is caused by the IP module.
  2. 6:  This step tests to see what DTCs are present. If DTC B0012 or B0016 is present, test the IP module for a short between high and low circuits in stage 1 or stage 2. If DTC B0013 or B0017 is present, test the IP module high and low circuits for an open and for high resistance in stage 1 or stage 2. If DTC B0014 or B0018 is present, test the IP module high and low circuits for a short to ground and for a short to voltage in stage 1 or stage 2.
DTC B0012, B0013, B0014, B0016, B0017, or B0018 (Buick)

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

  1. Turn OFF the ignition.
  2. Disconnect IP module in-line connector. Refer to Inflatable Restraint Instrument Panel Module Replacement (Rendezvous)  or Inflatable Restraint Instrument Panel Module Replacement (Aztek) .
  3. Inspect the component and harness sides of the in-line connector for the IP module 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. If the in-line connector for the IP module is damaged, the IP module must be replaced. Refer to Inflatable Restraint Instrument Panel Module Replacement (Rendezvous)  or Inflatable Restraint Instrument Panel Module Replacement (Aztek) .
  2. If the wiring harness side of the IP module 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.
  1. Use J 38715-80 adapter to connect the J 38715-A  SIR Driver/Passenger Load Tool to the harness side of the IP module connector. See Special Tools and Equipment . Use BASE OF COLUMN and PASSENGER INFLATOR connectors.
  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 B0012, B0013, B0014, B0016, B0017, or B0018 are current?		 Go to Step 5  Go to Step 7 
5
  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 IP 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.
Did you find and correct the condition?		 Go to Step 9  Go to Step 6

  1. If DTC B0012 or B0016 is present, test the IP module for a short between the high and low circuits in stage 1 or stage 2.
  2. If DTC B0013 or B0017 is present, test the IP module high and low circuits for an open and for high resistance in stage 1 or stage 2.
  3. If DTC B0014 or B0018 is present, test the IP module high and low circuits for a short to ground and for a short to voltage in stage 1 or stage 2.
  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 9  Go to Step 8

  1. Turn OFF the ignition.
  2. Replace the IP module. Refer to Inflatable Restraint Instrument Panel Module Replacement (Rendezvous)  or Inflatable Restraint Instrument Panel Module Replacement (Aztek) .
Did you complete the replacement?		 Go to Step 9  -

  1. Connect all SIR components.
  2. Turn ON the ignition, with the engine OFF.
  3. Use the scan tool in order to clear the DTCs.
  4. 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
