Diagnostic Test

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

CHECK TO SEE IF DTC IS CURRENT
1. With the scan tool, view DTCs.
  Is the status Active for this DTC or is the STARTS SINCE SET counter 2 or less?
  
  Yes
  - Go to step 2
  No
  - Go to step 3
CHECK THE PCM AND WIRING WITH THE TRANSMISSION SIMULATOR
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 personal injury or death.
3. Install the Transmission Simulator, Miller tool #8333A and the Electronic Transmission Adapter kit.
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 volts?
  
  Yes
  - Replace Transmission Solenoid/Pressure Switch Assembly per the Service Information.
  - Perform 42RLE 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. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace the PCM per the Service Information. With the scan tool, perform QUICK LEARN.
  - Perform 42RLE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
INTERMITTENT 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 DTC EVENT DATA to help identify the conditions in which the DTC was set.
5. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform 42RLE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Test Complete.
