Test Description

WARNING: This page is about a different car, the 2003 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.

2: This step verifies the ability of the TCM to command the TCC lock up PC solenoid valve.
3: This step verifies that the automatic transmission wiring harness and the TCC lock up PC solenoid valve have correct resistance.

DTC P0967

Step	Action	Values	Yes	No
1	Did you perform the Diagnostic System Check - Engine Controls?	-	Go to Step 2	Go to DIAGNOSTIC SYSTEM CHECK -- ENGINE CONTROLS
2	Install a scan tool. Turn the ignition ON, with the engine OFF. IMPORTANT: Before clearing the DTC, use the scan tool in order to record the ECM and the TCM Failure Records. Using the Clear Eng./Trans. DTC Info function erases the Failure Records from the ECM and TCM. Using the Clear Eng./Trans. DTC Info function erases stored DTCs in both the ECM and TCM. Record the DTC Failure Records. Clear the DTC. With a scan tool, select the TCC PC Solenoid Output Control. Increase and decrease the TCC lock up PC solenoid valve amperage. Observe the scan tool display. Does the TCC PC Sol. Actual Current reading vary from the TCC PC Sol. Ref. Current reading by more than the specified amount?	0.10 amps	Go to Step 3	Go to INTERMITTENTS
3	Turn OFF the ignition. Disconnect the AT inline 14-way connector. Additional DTCs may set. Using the digital multimeter (DMM) and the J-35616 GM-approved terminal test kit, measure the resistance between terminals 3 and 10 of the transmission side of the AT inline 14-way connector. Is the resistance less than the specified value?	3.8 ohm	Go to Step 4	Go to Step 5
4	Test the high control circuit (CKT 5511) of the TCC lock up PC solenoid valve and the low control circuit (CKT 5509) of the TCC lock up PC solenoid valve for being shorted together between the AT inline 14-way connector and the TCC lock up PC solenoid valve. Refer to Testing for Continuity in Wiring Systems. Did you find the condition?	-	Go to Step 8	Go to Step 9
5	Measure the resistance between terminal 3 and all other terminals, except terminal 10, of the transmission side of the AT inline 14-way connector. Refer to Testing for Continuity in Wiring Systems. Is the resistance between terminal 3 and any other terminal, except terminal 10, less than the specified value?	100 ohm	Go to Step 8	Go to Step 6
6	Test the high control circuit (CKT 5511) and the low control circuit (CKT 5509) of the TCC lock up PC solenoid valve for a short to voltage or a short together between the AT inline 14-way connector and the TCM. Refer to Circuit Testing in Wiring Systems. Did you find a condition?	-	Go to Step 7	Go to Step 10
7	Repair or replace the wiring harness. Refer to Wiring Repairs in Wiring Systems. Did you complete the replacement?	-	Go to Step 11	-
8	Repair or replace the internal automatic transmission wiring harness assembly (33). Refer to Wiring Harness Removal andWiring Repairs in Wiring Systems. Did you complete the replacement?	-	Go to Step 11	-
9	Replace the control valve body assembly (39). Refer to Control Valve Body Replacement . Is the replacement complete?	-	Go to Step 11	-
10	Replace the TCM. Refer to Transmission Control Module (TCM) Replacement . Is the replacement complete?	-	Go to Step 11	-
11	Perform the following procedure in order to verify the repair: Select DTC. Select Clear Info. Operate the vehicle for at least 12 seconds. Select Specific DTC. Enter DTC P0967. Does the DTC reset?	-	Go to Step 2	Go to Step 12
12	With the scan tool, observe the stored information, capture info and DTC info. Does the scan tool display any DTCs that you have not diagnosed?	-	Go to DIAGNOSTIC TROUBLE CODE DEFINITIONS	System OK
