DIAGNOSIS AND REPAIR WORK FLOW


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.
Can the door be locked with the Intelligent Key and door request switch?
YES - GO TO 2.
NO - Refer to Coupe.
2.CHECK ENGINE STARTING
Check that the engine starts when the Intelligent Key is inserted into the key slot.
Does the engine start?
YES - GO TO 3.
NO - Refer to Coupe.
3.CHECK POWER SUPPLY INDICATOR SWITCHING
Press push-button ignition switch and check that the position indicator switches from LOCK, through ACC to
ON when steering is locked.
Is each position indicator illuminating?
YES - GO TO 4.
