Test Description

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

The number below refers to the step number on the diagnostic table.

  1. 2:  Listen for a soft rattling sound when the solenoid energizes. Use a stethoscope if necessary.
DTC P2763

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. IMPORTANT:
    • Before clearing the DTC, use the scan tool in order to record the ECM Freeze Frame and the TCM Failure Records. Using the Clear Info function erases the Freeze Frame and Failure Records from the ECM and the TCM.
    • Using the Clear Info function erases stored DTCs in both the ECM and TCM.
  3. Record the DTC Freeze Frame and Failure Records.
  4. Clear the DTC.
  5. Use the scan tool in order to command the TCC PWM solenoid ON.
Does the solenoid operate?		 - Go to Step 8  Go to Step 3

  1. Turn OFF the ignition.
  2. Disconnect the AT 20-way inline harness connector.
  3. Install the J 45681  jumper harness to the TCM side of the 20-way connector.
  4. Turn ON the ignition with the engine OFF.
  5. With the test lamp connected to ground, probe the HSD2 circuit, terminal 17, of the J 45681  .
Does the test lamp illuminate?		 - Go to Step 4  Go to Step 6 
4
  1. Turn OFF the ignition.
  2. Install the J 45681  to the transmission side of the 20-way connector.
  3. Using the DMM, measure the resistance between terminal 17 and 20 of the J 45681  .

    Refer to Component Resistance .

Is the resistance within the specified range?		 10.0-13.6Ω Go to Step 5  Go to Step 7 
5
  1. Disconnect the TCM.
  2. Test the TCC PWM solenoid valve control circuit for a short to voltage. Refer to Testing for a Short to Voltage .
Did you find a condition?		 - Go to Step 9  Go to Step 8 
6
  1. Turn OFF the ignition.
  2. Disconnect the TCM.
  3. Test the HSD2 circuit from the TCM to the TCC PWM solenoid for an open circuit. Refer to Testing for Continuity .
Did you find a condition?		 - Go to Step 9  Go to Step 8 
7
  1. Remove the transmission oil pan.
  2. Test the TCC PWM solenoid wiring from the 20-way connector to the TCC PWM solenoid connector for a short to voltage. Refer to Testing for a Short to Voltage .
Did you find a condition?		 - Go to Step 10  Go to Step 11 
8 Replace the TCM.
Refer to Control Module References for replacement, setup and programming.
Is the action complete?		 - Go to Step 12  -

Is the action complete?		 - Go to Step 12  -
10 Replace the AT internal transmission wiring harness.
Refer to Transmission Internal Electrical Harness Replacement .
Is the action complete?		 - Go to Step 12  -
11 Replace the TCC PWM solenoid valve.
Refer to Torque Converter Clutch Solenoid Replacement .
Is the action complete?		 - Go to Step 12  -
12 Perform the following procedure in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Turn ON the ignition, with the engine OFF.
  4. Select Specific DTC.
  5. Enter DTC P2763.

Has the test run and passed?		 - Go to Step 13  Go to Step 2 
13 With the scan tool, observe the stored information, capture info and DTC info.
