CUSTOMER CONCERN
The vehicle was towed in with a no-start condition and DTC P0A0D stored.
CAUSE
Interlock testing confirmed a fault in the service safety-plug wiring. The Red interlock wire measured 5 volts with the circuit open and should be near 0 volts with the plug installed and the circuit grounded; the Black wire is the ground circuit.
CORRECTION
Repair the service safety-plug interlock wiring, then verify the high-voltage interlock closes and the vehicle starts.
