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 Service Information Tune-ups or Service Bulletins for any possible causes that may apply. 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 40TE TRANSMISSION VERIFICATION TEST. Refer to «40/41 TE TRANSMISSION VERIFICATION TEST»(ref-485570-S08458558962012071300000) .
3. CHECK THE WIRING AND CONNECTORS The conditions necessary to set the DTC are not present at this time. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit. Wiggle the wires while checking for shorted and open circuits. 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 40TE TRANSMISSION VERIFICATION TEST. Refer to «40/41 TE TRANSMISSION VERIFICATION TEST»(ref-485570-S08458558962012071300000) . No Test Complete.
