Diagnostic Test

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

DETERMINE IF RELATED TRANSMISSION TEMPERATURE DTCS ARE PRESENT
1. With the scan tool, check Transmission DTCs.
  Are there any other Transmission Temperature Sensor related 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 THE DTC IS ACTIVE
1. With the scan tool, view DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go to step 3
  No
  - Go to step 5
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 Input/Output switch to OFF.
6. With the scan tool, monitor the TRANS TEMP VOLTS while turning the Thermistor Voltage switch to all three positions on the Transmission Simulator.
7. Compare the scan tool readings with the numbers listed on the Transmission Simulator.
  Do the readings on the Transmission Simulator match the scan tool readings ± 0.2 of a volt?
  
  Yes
  - Go to step 4
  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. Check for any Service Bulletins and S.T.A.R. ON-LINE for any possible causes that may apply. If no problems are found, replace and program the Powertrain Control Module (PCM) 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 .
TRANSMISSION TEMPERATURE SENSOR
Repair
- Replace the Transmission Temperature Sensor (in the TRS Assembly) in accordance with the Service Information.
- 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 this 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.
