Fallback:
This fault causes an In Place fallback.
Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide
Possible Causes:
1) Battery bus fuse/circuit breaker is open
2) Low batteries
3) Damaged tower or OEM harness
4) Damaged transmission harness
5) Malfunctioning power connect relay
6) Malfunctioning system manager ECU
