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. 2:  This step tests for current PPS DTCs.
  2. 8:  This step tests for a short to ground, a high resistance or an open in the PPS class 2 serial data circuit.
  3. 9:  This step tests for a short to voltage in the PPS class 2 serial data circuit.
DTC 064

Step Action Yes No
Schematic Reference: SIR Schematics (AK5 or AJ7)  or SIR Schematics (AW9) 
Connector End View Reference: SIR Connector End Views  and Power Seat Systems Connector End Views
1 Did you perform the Diagnostic System Check - Vehicle? Go to Step 2  Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2 
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, request the passenger presence system (PPS) to flash DTCs. Refer to Passenger Presence System Flash Code Procedures .
Does the PPS indicate that DTC 064 is current?		 Go to Step 3  Go to Step 13 
3 With the scan tool request the supplemental inflatable restraint (SIR) DTCs.
Does the scan tool indicate that DTC B0098 is current?		 Go to DTC B0098  Go to Step 4

Did you find and correct the condition?		 Go to Step 13  Go to Step 7 
7
  1. Disconnect the sensing and diagnostic module (SDM) connector. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
  2. Inspect the SDM connector for corrosion or damage. 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 13  Go to Step 8 
8  Test the PPS class 2 serial data circuit for a short to ground, a high resistance or an open. Refer to Circuit Testing andWiring Repairs in Wiring Systems.
Did you find and correct the condition?		 Go to Step 13  Go to Step 9 
9 
  1. Turn ON the ignition, with the engine OFF.
  2. Test the PPS class 2 serial data circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 Go to Step 13  Go to Step 10 
10 Replace the PPS. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
Did you complete the replacement?		 Go to Step 11  -
11
  1. Reconnect all SIR and PPS system components.
  2. Verify that all components, connectors and connector position assurances (CPAs) are properly mounted.
  3. Use the scan tool in order to clear the SIR and PPS DTCs.
  4. Rezero the PPS. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
  5. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
Does the DTC reset?		 Go to Step 12  System OK
12 Replace the SDM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
Did you complete the replacement?		 Go to Step 13  -
13
  1. Reconnect all SIR and PPS system components.
  2. Verify that all components, connectors and CPAs are properly mounted.
  3. Use the scan tool in order to clear the SIR and PPS DTCs.
  4. Rezero the PPS. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming.
  5. 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
