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

CHECKING FOR LOSS OF PRIME DTC
1. With the scan tool, read DTCs.
  Is the DTC P0944 present also?
  
  Yes
  - See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing and perform the appropriate diagnostic procedure.
  No
  - Go to step 2
CHECK FOR RELATED TRANSMISSION DTCS
1. With the scan tool, read DTCs.
  Are any of the DTCs P0732, P0734 and/or P0846 present also?
  
  Yes
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 3
CHECK FOR CONTAMINATED FLUID
1. Check the transmission fluid for water or other contamination.
  Is the transmission fluid contaminated?
  
  Yes
  - Repair the cause of the transmission fluid contamination in accordance with the Service Information.
  No
  - Go to step 4
CHECK TO SEE IF DTC P0845 IS CURRENT
1. With the scan tool, read DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go to step 5
  No
  - Go to step 10
PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Ignition Switch Feed fuse from the TIPM.
  CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
  
  WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in possible serious or fatal injury.
3. Install the Transmission Simulator 8333A and the Electronic Transmission Adapter kit.
  NOTE: Check connectors - Clean/repair as necessary.
4. Ignition on, engine not running.
5. With the Transmission Simulator, turn the Pressure Switch selector switch to 2/4.
6. With the scan tool, monitor the 2/4 Pressure Switch state while pressing the Pressure Switch Test button on the Transmission Simulator.
7. Wiggle the wires leading to the PCM while pressing and holding the Pressure Switch Test button.
  Did the 2/4 Pressure Switch state change from open to closed when the test button was pressed, and remain closed while wiggling the wires?
  
  Yes
  - Disassemble and inspect the Valve Body in accordance with the Service Information. If no problems are found in the Valve Body, replace the Transmission Solenoid/TRS Assembly.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 6
(T47) 2/4 PRESSURE SIGNAL CIRCUIT OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C4 harness connector.
3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
  CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install PCM Pinout Box 8815 to perform diagnosis.
4. Measure the resistance of the (T47) 2/4 Pressure Signal circuit between the appropriate terminal of the PCM Pinout Box 8815 and the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for an open.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 7
(T47) 2/4 PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (T47) 2/4 Pressure Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to ground.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 8
(T47) 2/4 PRESSURE SIGNAL CIRCUIT SHORTED TO VOLTAGE

1. Ignition on, engine not running.
2. With the scan tool in the TIPM, actuate the TCM output.
3. Measure the voltage of the (T47) 2/4 Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to voltage.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 9
TRANSMISSION CONTROL OUTPUT CIRCUIT OPEN

1. While still actuating the TCM output in the TIPM and using a 12-volt test light connected to ground, check (T16) Transmission Control Output circuit in the Transmission Solenoid/TRS Assembly harness connector.
  NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Replace and program the Powertrain Control Module in accordance with the Service Information. With the scan tool perform Quick Learn.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Repair the Transmission Control Output circuit for an open or high resistance. If the fuse is open make sure to check for a short to ground.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 62TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Test Complete.
