Diagnostic depth
Detection
The coordinator has not been able to verify the engine control unit. The engine control unit is perceived as being faulty or not intended for this vehicle.
Possible cause
The engine control unit PIN does not agree with the coordinator PIN code. Both control units must have the same code. The engine control unit may be either unprogrammed or programmed with the wrong code in relation to the coordinator.
