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. 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 (2.4L BAS)

Step Action Value(s) Yes No
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle
2
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. Select TR Sw. on the scan tool.
  4. With the scan tool, observe the TR Sw. display while selecting each transmission range: P, R, N, D4, D3, D2 and D1.
Does each selected transmission range match the scan tool TR Sw. display?		 - Go to Testing for Intermittent Conditions and Poor Connections 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
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 HI for all range signal states?		 - Go to Step 13  Go to Step 5 
5 
  1. Turn OFF the ignition.
  2. Disconnect the PNP switch connector.
  3. Turn ON the ignition, with the engine OFF.
Does the scan tool TR Sw. A/B/C/P parameter indicate HI 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 the TR signal A circuit of the PNP switch connector to ground. See Special Tools .
  2. Measure the voltage from the TR signal B circuit of the PNP switch connector to ground.
  3. Measure the voltage from the TR signal C circuit of the PNP switch connector to ground.
  4. Measure the voltage from the TR signal P circuit of the PNP switch connector to ground.
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 the TR signal A circuit of the PNP switch connector to ground while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the TR signal A circuit is grounded, do any other signal circuits indicate LOW?		 - Go to Step 12  Go to Step 8 
8  Connect a fused jumper wire from the TR signal B circuit of the PNP switch connector to ground while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the TR signal B circuit is grounded, do any other signal circuits indicate LOW?		 - Go to Step 12  Go to Step 9 
9  Connect a fused jumper wire from the TR signal C circuit of the PNP switch connector to ground while monitoring the scan tool TR Sw. A/B/C/P parameter.
When the TR signal C circuit is grounded, do any other signal circuits indicate LOW?		 - Go to Step 12  Go to Step 14 
10 Test the TR signal circuits of the PNP switch that did not indicate HI for a short to ground.
Refer to Testing for Short to Ground and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
11 Test the TR signal circuits of the PNP switch that did not indicate proper voltage for an open.
Refer to Testing for Continuity and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
12 Test the affected TR signal circuits of the PNP switch for a shorted together condition.
Refer to Circuit Testing and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 16  Go to Step 15 
13 Test the ground circuit of the PNP switch for an open.
Refer to Testing for Continuity and Wiring Repairs .
Did you find and correct the condition?		 - Go to Step 16  Go to Step 14 
14 Replace the PNP switch.
Refer to Park/Neutral Position Switch Replacement .
Did you complete the replacement?		 - Go to Step 16  -
15 Replace the TCM.
Refer to Control Module References for replacement, setup, and programming.
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.

Has the test run and passed?		 - Go to Step 17  Go to Step 2 
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 (DTC) List - Vehicle System OK
