There is an open in the circuit.
The solenoid has failed.
The ECM has failed. This is unlikely.Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.Note: Ensure that CID 0708 FMI 05 for the solenoid is active. Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. DO NOT start the engine.
