Diagnostic Test

CHECK DTCS
1. With the scan tool, read DTCs.
  Are there any TIPM TCM Power Control Circuit or TCM Power Input DTCs present?
  
  Yes
  - See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing and perform the appropriate diagnostic procedure.
  No
  - Go to step 2
CHECK IF DTC P0755 IS PRESENT
1. Ignition on, engine not running.
2. With the scan tool, erase all Transmission DTCs.
3. Turn the ignition off to the lock position.
4. Remove the Starter Relay.
  CAUTION: Removal of the Starter Relay will prevent the vehicle from being started in gear.
  
  WARNING: The Starter Relay must be removed from the PDC. Failure to do so may result in possible serious or fatal injury.
  
  NOTE: Failure to remove the Starter Relay can cause a Transmission - No Response condition.
5. Install the Transmission Simulator 8333.
6. Ignition on, engine not running.
7. With the scan tool, actuate the 2C Solenoid.
  Did the 2C Solenoid LED blink on and off on the Transmission Simulator?
  
  Yes
  - Go to step 3
  No
  - Go to step 5
CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
1. With the Transmission simulator still connected, continue to actuate the 2C solenoid for two minutes.
2. After two minutes of actuation, with the scan tool, stop the actuation and check for transmission DTCs.
  Did the DTC P0755 reset during the actuation test?
  
  Yes
  - Go to step 5
  No
  - Go to step 4
CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
1. With the Transmission simulator still connected, continue to actuate the 2C solenoid for another two minutes while wiggling the related wiring harness and connectors.
2. With the scan tool, stop the actuation and check for transmission DTCs.
  Did the DTC P0755 reset during the actuation test?
  
  Yes
  - Repair wiring harness or connectors as necessary.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information. Note: Do NOT replace the entire Valve Body.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
CHECK THE (T219) 2C CONTROL CIRCUIT SHORT FOR A SHORT TO ANOTHER CIRCUIT

1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Simulator 8333.
3. Disconnect the PCM harness connectors.
4. Measure the resistance between the (T219) 2C Control circuit and all other circuits in the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance below 5.0 Ohms between the (T219) 2C Control circuit and any other circuit(s) in the Transmission Solenoid/TRS Assembly harness connector?
  
  Yes
  - Repair the (T219) 2C Control circuit for a short to another circuit(s).
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 6
CHECK THE (T219) 2C CONTROL CIRCUIT FOR AN OPEN

1. Connect the PCM Pinout Box 8815 to the PCM C4 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 the PCM Pinout Box 8815 to perform diagnosis.
2. Measure the resistance of the (T219) 2C Control circuit between the Transmission Solenoid/TRS Assembly harness connector and the appropriate terminal of the PCM Pinout Box 8815.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T219) 2C Control circuit for an open.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 7
CHECK THE (T219) 2C CONTROL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T219) 2C Control circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T219) 2C Control circuit for a short to ground.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM in accordance with the Service Information. With the scan tool, perform Quick Learn.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
