Test Description

WARNING: This page is about a different car, the 2007 Saturn Vue. 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 to see if the malfunction is caused by the IPM.
  2. 6:  Tests to see what DTCs are present. If DTC B0012 or B0016 is present, test for a short between the IPM high and low circuits in stage 1 or stage 2. If DTC B0013 or B0017 is present, test the IPM 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 IPM high and low circuits for a short to ground and for a short to voltage in stage 1 or stage 2.

  1. Turn OFF the ignition.
  2. Disconnect the instrument panel module (IPM) connector. Refer to Inflatable Restraint Instrument Panel Module Replacement .
  3. Inspect the component and harness sides of the connector for the IPM for damage or corrosion that may cause the malfunction. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Does the connector exhibit any signs of damage or corrosion?		 Go to Step 3  Go to Step 4

  1. If the component side of the IPM connector is damaged, the IPM must be replaced. Refer to Inflatable Restraint Instrument Panel Module Replacement .
  2. If the wiring harness side of the IPM connector is damaged, replace the harness side of the connector. Refer to Connector Repairs .
Did you complete the repair?		 Go to Step 9  -

    IMPORTANT: When installing SA9409Z-A  SIR Driver/Passenger Load Tool for testing the dual stage IPM, the correct 4-way load tool adapter connector must be used. See Special Tools . 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 SA9409Z-A  to the harness side of the IPM connector. See Special Tools . 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

  1. Turn OFF the ignition.
  2. Disconnect and remove both the SA9409Z-A  and adapter. See Special Tools .
  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 IPM stage 1 or stage 2 high and/or low circuits. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs .
Did you find and correct the condition?		 Go to Step 9  Go to Step 6

    IMPORTANT: If scan tool displays multiple codes diagnose the open code first.
  1. If DTC B0012 or B0016 is present, test for a short between the IPM high and low circuits in stage 1 or stage 2.
  2. If DTC B0013 or B0017 is present, test the IPM 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 IPM 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 .
Did you find and correct the condition?		 Go to Step 9  Go to Step 8
