Basic Inspection

The engine start function, door lock function, power distribution system and NATS-IVIS/NMS 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 system 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 DLK section if the door cannot be unlocked.

Can the door be locked with the Intelligent Key and door request switch? YES >> GO TO 2

NO >> Refer to DLK-187, "Symptom Table".

2.CHECK ENGINE STARTING

1. Checks that the engine starts when operating the Intelligent Key inserted into the key slot.

Does the engine start? YES >> GO TO 3

NO >> Refer to SEC-204, "Symptom Table".

3.CHECK STEERING LOCKING

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 >> Refer to DLK-69, "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. Checks that the position indicator is illuminated at different positions of the circuit.

Is each position indicator illuminating? YES >> GO TO 5

NO >> Refer to PCS-80, "Component Function Check".

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.

>> Refer to SEC-13, "Vehicle Security Operation Check".

>> GO TO 2

2.CHECK SECURITY INDICATOR LAMP

1. Lock doors using Intelligent Key or mechanical key.

2. Check that security indicator lamp illuminates for 30 seconds.

Security indicator lamp should illuminate.

OK >> GO TO 3

NG >> Perform diagnosis and repair. Refer to SEC-124, "Component Function Check".

3.CHECK ALARM FUNCTION

1. After 30 seconds, security indicator lamp will start to blink.

2. Open any door or hood before unlocking with Intelligent Key or mechanical key, or open trunk lid without Intelligent Key or mechanical key.

Do alarm function properly.

OK >> GO TO 4

NG >> Check the following.

• The vehicle security system does not phase in alarm mode. Refer to SEC-205, "Symptom Table".

• Alarm (horn, headlamp and hazard lamp) do not operate. Refer to SEC-205, "Symptom Table".

4.CHECK ALARM CANCEL OPERATION
