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.

  1. 5:  By disconnecting the TR switch, the ground path for all TR switch circuits would be removed and the TCM should recognize all circuits as open. The scan tool should display HI for all range signals.
  2. 6:  This step tests the TR switch wiring for an open or lack of signal voltage from the TCM.
  3. 7:  This step tests the TR switch wiring and the TCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal A should change to LOW.
  4. 8:  This step tests the TR switch wiring and the TCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal B should change to LOW.
  5. 9:  This step tests the TR switch wiring and the TCM by providing a ground path through a fused jumper wire. When grounded, the scan tool range signal C should change to LOW.
DTC P0705

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
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
    3. IMPORTANT: Before clearing the DTC, use the scan tool in order to record the Freeze Frame and Failure Records. Using the Clear Eng./Trans. DTC Info function erases the Freeze Frame and Failure Records from the TCM.
  3. Record the DTC Freeze Frame and Failure Records.
  4. Clear the DTC.
  5. Select TR Sw. on the scan tool.
  6. With a scan tool, observe the TR Sw. display while selecting each transmission range: P, R, N, D, I, and L.
Does each selected transmission range match the scan tool TR Sw. display?		 - Go to INTERMITTENTS Go to Step 3

  1. Inspect the PNP switch assembly for the following:
  2. Inspect the shift cable for the following:
    • Damaged or stretched cable
    • Proper adjustment

      Refer to Shift Cable Replacement.

Did you find and correct a condition?		 - Go to Step 16  Go to Step 4 
4 With the scan tool, observe the TR Sw. A/B/C/P display.
Does the scan tool TR Sw. A/B/C/P parameter indicate LOW for all range signal states?		 - Go to Step 13  Go to Step 5 
5 
  1. Turn OFF the ignition.
  2. Disconnect the TR switch 10-way connector.
  3. Turn ON the ignition, with the engine OFF.
Does the scan tool TR Sw. A/B/C/P parameter indicate LOW for all range signal states?		 - Go to Step 6  Go to Step 10 
6 
  1. Using the DMM and the J-35616  GM-approved terminal test kit, measure the voltage from terminal 5 of the TR switch 10-way connector to the battery positive terminal.
  2. Measure the voltage from terminal 6 of the TR switch 10-way connector to B+.
  3. Measure the voltage from terminal 8 of the TR switch 10-way connector to B+.
  4. Measure the voltage from terminal 10 of the TR switch 10-way connector to B+.
Does the voltage measure within the specified value at all four terminals?		 10-12 V Go to Step 7  Go to Step 11 
7  Connect a fused jumper wire from terminal 10 of the TR switch 10-way connector, signal A circuit, to the battery positive terminal while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the signal A circuit (CKT 771) is jumpered to voltage, do any other signal circuits indicate HI?		 - Go to Step 12  Go to Step 8 
8  Connect a fused jumper wire from terminal 6 of the TR switch 10-way connector, signal B circuit, to the battery positive terminal while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the signal B circuit (CKT 772) is jumpered to voltage, do any other signal circuits indicate HI?		 - Go to Step 12  Go to Step 9 
9  Connect a fused jumper wire from terminal 5 of the TR switch 10-way connector, signal C circuit, to the battery positive terminal while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the signal C circuit (CKT 773) is jumpered to voltage, do any other signal circuits indicate HI?		 - Go to Step 12  Go to Step 14 
10 Test the signal circuits (CKTs 771, 772, 773 and 776) of the TR switch that did not indicate LOW for a short to voltage.
Refer to Testing for a Short to Voltage and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
11 Test the signal circuits (CKTs 771, 772, 773 and 776) of the TR switch that did not indicate proper voltage for an open.
Refer to Testing for Continuity andWiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
12 Test the affected signal circuits of the TR switch for a shorted together condition.
Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
13 Test the voltage supply circuit (CKT 639) of the TR switch for an open, high resistance or short to ground.
Refer to Testing for Continuity andWiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 16  Go to Step 14 
14 Replace the TR switch. The TR switch is part of the park/neutral position switch.
Refer to Park/Neutral Position Switch Replacement .
Did you complete the replacement?		 - Go to Step 16  -
15 Replace the TCM.
Refer to Transmission Control Module (TCM) Replacement .
Did you complete the replacement?		 - Go to Step 16  -
16 Perform the following procedure in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Road test the vehicle.
  4. Select Specific DTC.
  5. Enter DTC P0705.

Does the DTC reset?		 - Go to Step 2  Go to Step 17 
17 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
