The System Manager checks the integrity of the Power Connect Relay Coil. If it detects a short to ground or open it sets a fault.
Fallback
This fault causes and In Place fallback while moving and a failure during system initialization.
Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide
Possible Causes:
1) System manager ECU
2) Tower harness
3) Power connect relay
