Diagnostic Test

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

CHECK FOR AN ACTIVE DTC
NOTE:
Pressure Control Solenoid 1 is referred to as Torque Converter Clutch (TCC) solenoid in the Service Information and SLU in the Wiring Information.
1. With the scan tool, read TCM DTCs and record on the repair order.
2. Record the Event Data and Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Event and Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read TCM DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2.
  No
  - Go To 7.
CONFIRM RESISTANCE OF THE TORQUE CONVERTER CLUTCH (TCC) SOLENOID
NOTE:
Perform this step when the transmission fluid temperature is about 20°C (68°F).
1. Disconnect connector B of the Transmission Control Module (TCM).
2. On the wiring of the solenoid valve on Transmission Control Module (TCM) side, measure the resistance on terminals D and Q.
  Is resistance between 5.0 and 5.6 ohms?
  
  Yes
  - Go To 5.
  No, measured resistance ABOVE 5.6 Ohms
  - Go To 3.
  No, measured resistance BELOW 5.0 Ohms.
  - Go To 5.
CHECK THE TORQUE CONVERTER CLUTCH (TCC) SOLENOID SIGNAL CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Disconnect the transmission pass through harness connector.
2. Measure the resistance of the Torque Converter Clutch (TCC) solenoid (SLU) Signal circuit between the Transmission harness connector and the TCM harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 4.
  No
  - Repair the Torque Converter Clutch (TCC) solenoid (SLU) Signal circuit for an open or high resistance.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
CHECK THE TORQUE CONVERTER CLUTCH (TCC) SOLENOID SIGNAL RETURN CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Disconnect the transmission pass through harness connector.
2. Measure the resistance of the Torque Converter Clutch (TCC) solenoid (SLU) Signal Return circuit between the Transmission Assembly harness connector and the TCM harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Replace the Torque Converter Clutch (TCC) solenoid (SLU) and Internal Transmission Harness in accordance with the Service Information.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Repair the Torque Converter Clutch (TCC) solenoid (SLU) Signal Return circuit for an open or high resistance.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
CHECK THE TORQUE CONVERTER CLUTCH (TCC) SOLENOID SIGNAL FOR A SHORT TO GROUND
1. Connect the Transmission Harness Pass Through Connector.
2. Check for continuity between ground and the Torque Converter Clutch (TCC) solenoid (SLU) Signal circuit at the TCM harness connector.
  Is there continuity between ground and the Torque Converter Clutch (TCC) solenoid (SLU) Signal circuit?
  
  Yes
  - Repair the Torque Converter Clutch (TCC) solenoid (SLU) Signal circuit for a short to ground.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6.
CHECK THE TORQUE CONVERTER CLUTCH (TCC) SOLENOID SIGNAL RETURN CIRCUIT FOR A SHORT TO GROUND
1. Connect the transmission pass through harness connector.
2. Check for continuity between ground and the Torque Converter Clutch (TCC) solenoid (SLU) Signal Return circuit at the TCM harness connector.
  Is there continuity between ground and the Torque Converter Clutch (TCC) solenoid (SLU) Signal Return circuit?
  
  Yes
  - Repair the Torque Converter Clutch (TCC) solenoid (SLU) Signal Return circuit for a short to ground.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Replace the TCM in accordance with the Service Information. Refer to MODULE, TRANSMISSION CONTROL (TCM), REMOVAL AND INSTALLATION .
CHECK FOR AN INTERMITTENT CONDITION
NOTE:
The conditions necessary to set the DTC are not present at this time. The code set because of an intermittent condition. Try to determine the cause in this step.

Turn the ignition off.
1. Disconnect all TCM harness connectors.
2. Disconnect all related in-line harness connections (if equipped).
3. Disconnect the related component harness connectors.
4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Terminals that have been pushed back into the connector cavity.
  - Perform a terminal drag test on each connector terminal to verify proper terminal tension.
5. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
6. Wiggle the wires while checking for shorted and open circuits.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  No
  - Perform the TRANSMISSION VERIFICATION TEST. Refer to TRANSMISSION VERIFICATION TEST .
  - Test complete.
