Diagnostic Test

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

DETERMINE IF RELATED DTCS ARE PRESENT
1. With the scan tool, check Transmission DTCs.
  Are there any line pressure sensor or throttle position sensor DTCs present?
  
  Yes
  - See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing and perform the appropriate diagnostic procedure.
  No
  - Go to 2
CHECK TO SEE IF DTC IS CURRENT
1. With the scan tool, Check the Starts Since Set counter for P0714.
  NOTE: This counter only applies to the last DTC set.
  
  Is the Starts Since Set counter 2 or less?
  
  Yes
  - Go to 3
  No
  - Go to 4
TRANSMISSION TEMPERATURE SENSOR
1. Turn the ignition off to the lock position.
2. Remove the Starter Relay.
  NOTE: Removal of the Starter Relay is to prevent a Transmission, NO RESPONSE, condition and disable the starter.
3. Install the Transmission Simulator 8333A.
  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 a non-fluctuating scan tool reading ± 0.2 of a volt?
  
  Yes
  - Replace Transmission Solenoid/TRS assembly in accordance with the appropriate service information.
  - 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 appropriate 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 .
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 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Test Complete.
