Overview:
This fault code indicates an electrical failure of the relay that allows the engine to start after start-up conditions are met.
Detection:
Starting at key-on and throughout operation, the System Manager constantly measures the circuit. A failure mode of short to battery, short to ground, or open circuit is detected.
Fallback:
The start enable relay has no fallback, however, if the failure occurred before the engine was started, it is possible the engine will not start.
Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide
Possible Causes:
1) Relay coil open or shorted
2) Damaged tower or OEM harness
3) Malfunctioning system manager ECU
