P0613-INTERNAL TRANSMISSION PROCESSOR

For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

Theory of Operation

The internal watchdog is a separate hardware circuit which continuously monitors the microprocessor. To make sure the transmission is operating properly, the watchdog must receive a signal from the microprocessor within a specific time window. MIL on after 10 seconds of vehicle operation and transmission will be placed in limp-in.

- When Monitored:
After the ignition key is turned to the run position and 60 seconds thereafter.

- Set Condition:
Either of the following conditions occur 3 times in less than 590 milliseconds: The watchdog line remains high after the watchdog test or the transmission relay coil is energized and remains on after the watchdog delay expires.





Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. Initial Inspection and Diagnostic Overview
PCM - INTERNAL ERROR
1. Using the schematics as a guide, inspect the wiring and connectors. Repair as necessary. Pay particular attention to all power and ground circuits.

Repair

- Replace the Powertrain Control Module. With the scan tool perform Quick Learn, Quick Learn Procedure then program Pinion Factor in the Front Control Module.
- Perform 42RLE TRANSMISSION VERIFICATION TEST. Transmission Verification Test
