Basic Inspection

PRE-INSPECTION FOR DIAGNOSTIC


Basic Inspection

The engine start function, door lock function, power distribution system and NATS-IVIS/NVIS in the Intelligent Key system are closely related to each other regarding control. Narrow down the functional area in question by performing basic inspection to identify which function is malfunctioning. The vehicle security function can operate only when the door lock and power distribution systems are operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by performing the vehicle security operation check after basic inspection.
1.CHECK DOOR LOCK OPERATION
1. Check the door lock for normal operation with the Intelligent Key controller and door request switch.
Successful door lock operation with the Intelligent Key and request SW indicates that the remote keyless entry receiver is functioning normally.
Identify the malfunctioning point by referring to the Door & Lock if the door cannot be unlocked.
Can the door be locked with the Intelligent Key and door request switch?
YES - GO TO 2
NO - Intelligent Key System Symptoms.
2.CHECK ENGINE STARTING
1. Check that the engine starts when the Intelligent Key is inserted into the key slot.
Does the engine start?
YES - GO TO 3
NO - Intelligent Key System/Engine Start Function Symptoms.
3.CHECK STEERING LOCK
1. Does the steering lock when operating door switch after switching the power supply from ON position (or
ACC position) to LOCK position?
If door switch is malfunctioning, BCM cannot lock the steering. If BCM does not detect DTC, steering lock unit is normal.
Does steering lock?
YES - GO TO 4
NO - Component Function Check.
4.CHECK POWER SUPPLY INDICATOR SWITCHING
1. Press push-button ignition switch and position indicator will switch from LOCK, ACC to ON gradually when steering is locked. Check that the position indicator is illuminated at different positions of the circuit.
Is each position indicator illuminating?
YES - GO TO 5
NO - SEC.
5.CHECK VEHICLE SECURITY SYSTEM
1. Check the vehicle security system for normal operation.
The vehicle security function can operate only when the door lock and power distribution functions are operating normally.
Therefore, it is easy to identify any factor unique to the vehicle security by performing the vehicle security operation check after this basic inspection.
