Test Description

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. 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 I/P module.
  2. 6:  This step tests to see what DTCs are present. If DTC B0012 or B0016 is present, test the I/P module for a short between high and low circuits in stage 1 or stage 2. If DTC B0013 or B0017 is present, test the I/P 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 I/P 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

  1. Turn OFF the ignition.
  2. Disconnect instrument panel (I/P) module inline connector. Refer to Inflatable Restraint Instrument Panel Module Replacement  for location of connector.
  3. Inspect the component and harness sides of the inline connector for the I/P 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 inline connector for the I/P module 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.

    IMPORTANT: If scan tool displays multiple codes, diagnose the open code first.
  1. Use the J 38715-80 Adapter to connect the J 38715-A  SIR Driver/Passenger Load Tool or Saturn SA9409Z-A to the harness side of the I/P module inline connector. See Special Tools . Use BASE of COLUMN and PASSENGER INFLATOR connectors located on the load tool.
  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

  1. Turn OFF the ignition.
  2. Disconnect and remove both the J 38715-A  or Saturn SA9409Z-A and adapter. See Special Tools .
  3. Disconnect the inflatable restraint sensing and diagnostic module (SDM) connector. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
  4. Inspect the SDM connector for damage or corrosion that may cause a malfunction in the I/P 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 I/P module circuits 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 I/P 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 I/P 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. 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
