Test Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. 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:  Tests if the malfunction is caused by the I/P module.
  2. 6:  Determines which DTCs are present. If DTC B0012 or B0016 is present, test the I/P module for a short between high circuits and low circuits in stage 1 or stage 2. If DTC B0013 or B0017 is present, test the I/P module high circuits 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

2
  1. Turn OFF the ignition.
  2. Disconnect the instrument panel (I/P) module in-line connector. Refer to Inflatable Restraint Instrument Panel Module Replacement  .
  3. Inspect the component and harness sides of the in-line 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 connector exhibit any signs of damage or corrosion?		 Go to Step 3  Go to Step 4

  1. If the in-line 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: When installing J 38715-A  SIR Driver/Passenger Load Tool for testing the dual stage I/P module, the correct 4-way load tool adapter connector must be used. See Special Tools and Equipment . 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  to the harness side of the I/P 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 I/P module stage 1 or stage 2 high circuits 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 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. If any of the conditions exist, 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 I/P module. Refer to Inflatable Restraint Instrument Panel Module Replacement  .
Did you complete the replacement?		 Go to Step 9  -

  1. Turn OFF the ignition.
  2. Replace the SDM. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement  .
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
