Overview:
The code indicates an internal failure of the Transmission ECU.
Detection:
The Transmission ECU checks the program memory every time the key is turned on. If the transmission is able to detect a failure within its own memory, it sets this fault code.
Fallback:
This fault causes an In Place fallback while moving and a failure during system initialization.
Required Tools:
1) Basic Hand Tools
2) AutoSelect/AutoShift Troubleshooting Guide
Possible Causes:
1) Improper configuration software
2) Faulty Transmission ECU
