Test Description

WARNING: This page is about a different variant/trim than selected.

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

  1. 4:  Disconnecting the transmission range switch, the ground path of all PNP switch circuits would be removed and the PCM would recognize all circuits as open. The scan tool will display HI for all range signals.
  2. 9:  This step verifies the repair of the PNP switch wiring for an open or the lack of the signal voltage from the PCM.

Did you find and correct a condition?		 - Go to Step 9  Go to Step 4 
4  With the scan tool, observe the PNP Sw. A/B/C/P display.
Does the scan tool PNP Sw. A/B/C/P parameter indicate HI for all range, signal states?		 - Go to Step 5  Go to Step 8 
5 Test the affected signal circuits of the PNP switch for a short to ground.
Did you find and correct the condition?		 - Go to Step 9  Go to Step 6 
6 Test the ground circuit of the PNP switch for a open.
Did you find and correct the condition?		 - Go to Step 9  Go to Step 7 
7 Replace the PNP switch. Refer to Park/Neutral Position Switch .
Did you complete the replacement?		 - Go to Step 9  -
8 Replace the powertrain control module (PCM). Refer to Powertrain Control Module Programming and Setup in Programming and Setup.
Did you complete the replacement?		 - Go to Step 9  -
9  Perform the following procedures in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Drive the vehicle greater than 8 km/h (5 mph) for a short distance, then stop the vehicle.
  4. Select each transmission range: P, R, N, D, 2 and L.
  5. Place the transmission in PARK.
  6. Select Specific DTC. Enter DTC P0705.

Has the test run and passed?		 - Go to Step 10  Go to Step 2 
10 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 in Vehicle DTC Information System OK
