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 number below refer to the step numbers on the diagnostic table.

2: This step is requesting the PPS to flash internal DTCs, checking to see if DTC 036 is current.
7: Test the occupant sensor serial data circuit for a short to ground, a high resistance, or an open.
8: Test the occupant sensor serial data circuit for a short to voltage.

DTC 036

Step	Action	Yes	No
Schematic Reference: SIR Schematics Connector End View Reference: SIR Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Turn ON the ignition, with the engine OFF. 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 036 is current?	Go to Step 3	Go to Diagnostic Aids
3	Turn OFF the ignition. Disconnect the PPS module connector. Refer to Control Module References for replacement, setup, and programming. Inspect the PPS module terminals and harness connector for damage or corrosion. Does the PPS module terminals or harness connector exhibit any signs of damage or corrosion?	Go to Step 4	Go to Step 5
4	If the PPS module terminals are damaged, replace the PPS. Refer to Control Module References for replacement, setup, and programming. If the PPS harness connector is damaged, replace the connector. Refer to Connector Repairs . Did you complete the replacement?	Go to Step 10	-
5	Disconnect the main seat harness connector located under the RF seat. Refer to Power Seat Connector End Views . Inspect both halves of the connector for corrosion or damage. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 10	Go to Step 6
6	Disconnect the sensing and diagnostic module (SDM) connector. Refer to Control Module References for replacement, setup, and programming. Inspect the SDM connector for corrosion or damage. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 10	Go to Step 7
7	Test the occupant sensor serial data circuit for a short to ground, a high resistance, or an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 10	Go to Step 8
8	Turn ON the ignition, with the engine OFF. Test the occupant sensor serial data circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 10	Go to Step 9
9	Turn OFF the ignition. IMPORTANT: The PPS, heated seat element, and seat bottom cushion is only serviced as a complete kit. Replace the PPS. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	Go to Step 10	-
10	Reconnect all SIR and PPS system components. Verify that all components, connectors, and connector position assurances (CPAs) are properly mounted. Use the scan tool in order to clear the SIR and PPS DTCs. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text. Does the DTC reset?	Go to Step 11	System OK
11	Replace the SDM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	Go to Step 12	-
12	Reconnect all SIR and PPS system components. Verify that all components, connectors, and CPAs are properly mounted. Use the scan tool in order to clear the SIR and PPS DTCs. 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
