The engine start function, door lock function, power distribution system and NATS-IVIS/NMS in the Remote
Keyless Entry 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 func-
tion 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 keyfob.
Successful door lock operation with the keyfob indicates that the remote keyless entry receiver is function-
ing normally.
Identify the malfunctioning point by referring to the DLK section if the door cannot be unlocked.
Can the door be locked with the keyfob?
YES
>> GO TO 2
NO
>> Refer to
DLK-415, "INTELLIGENT KEY : Symptom Table"
2.
CHECK ENGINE STARTING
1. Checks that the engine starts when operating the keyfob inserted into the key slot.
Does the engine start?
YES
>> GO TO 3
NO
>> Refer to
.
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-293, "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
>> Refer to
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.

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-514, "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 keyfob or mechanical key, or open trunk lid without keyfob
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
.
• Alarm (horn, headlamp and hazard lamp) do not operate. Refer to
4.
CHECK ALARM CANCEL OPERATION
Unlock any door or open trunk lid using keyfob or mechanical key.
Alarm (horn, headlamp and hazard lamp) should stop.

(In this step, initialization procedure by CONSULT-III is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT-III Oper-
ation Instruction.
• If multiple keys are attached to the key holder, separate them before work.
• Distinguish keys with unregistered key ID from those with registered ID.

INPUT/OUTPUT SIGNAL CHART
SYSTEM DESCRIPTION
• The engine start function of remote keyless entry system is a system that makes it possible to start and stop
the engine without removing the key. It verifies the electronic ID using two-way communications when press-
ing the push-button ignition switch while carrying the keyfob, which operates based on the results of elec-
tronic ID verification for keyfob using two-way communications between the keyfob and the vehicle.
NOTE:
The driver should carry the keyfob at all times.
• keyfob has 2 IDs [for keyfob and for NVIS (NATS)]. It can perform the door lock/unlock operation and the
push-button ignition switch operation when the registered keyfob is carried.
• When the keyfob battery is discharged, it can be used as emergency back-up by inserting the keyfob to the
key slot. At that time, perform the NVIS (NATS) ID verification. If it is used when the keyfob is carried, per-
form the keyfob ID verification.
• If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and initiating the engine will be possible.
• If the door lock/unlock operation is performed when the keyfob battery is discharged, all doors lock/unlock
can be performed by operating the driver door key cylinder using the mechanical key set in the keyfob.
• keyfob can be registered up to 4 keys (Including the standard keyfob) on request from the owner.
NOTE:
• Refer to
DLK-246, "INTELLIGENT KEY : System Description"
for any functions other than engine start
function of remote keyless entry system.
