Pre-Inspection for Multi-System Diagnostic
The engine start function, door lock function, power distribution system and NATS-IVIS/NVIS are closely related to each other. Narrow down the system in question by performing this inspection to identify which system is malfunctioning. For example, the vehicle security system can operate only when the door lock and power distribution system are operating normally.
1.CHECK DOOR LOCK OPERATION
Check the door lock for normal operation with the Intelligent Key and door request switch.
Successful door lock operation with the Intelligent Key and request switch indicates that the remote keyless entry receiver and inside key antenna required for engine start are functioning normally.
2.CHECK ENGINE STARTING
Check that the engine starts when the Intelligent Key is inserted into the key slot.
3.CHECK POWER SUPPLY INDICATOR SWITCHING
Press push-button ignition switch and check that the position indicator switches from LOCK, through ACC to ON.
4.CHECK VEHICLE SECURITY SYSTEM
Check the vehicle security system for normal operation. Refer to SEC-7, "Vehicle Security Operation Check".
