System DescriptionINFOID:0000000001728855
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Map lamp, interior room lamp, vanity lamps and trunk room lamp.
The timer control functions of the BCM activate based on inputs from the remote keyless entry receiver, the
key cylinder lock/unlock switch, the door switches, the key switch and key lock solenoid (without Intelligent
Key) or the key switch and ignition knob switch (with Intelligent Key).
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM
begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
 When the front door LH is unlocked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 When a door opens → closes and the Intelligent Key is not inserted in the key slot.
Timer control is canceled under the following conditions.
 When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 A door is opened (door switch turns ON).
 Intelligent Key is inserted into the key slot.
Interior lamp operational settings can be changed with the function setting of CONSULT-III.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the battery 30 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when

PRE-INSPECTION FOR DIAGNOSTIC
Basic InspectionINFOID:0000000001697628
The engine start function, door lock function, power distribution system and NATS-NVIS 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 keyfob or Intelligent Key (if equipped) and door request
switch.
Successful door lock operation with the keyfob or Intelligent Key (if equipped) and request SW indicates
that the remote keyless entry receiver and inside key antenna (with Intelligent Key) required for engine
start are 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-191, "
DOOR LOCK AND UNLOCK SWITCH : Symptom Table" (with Intelligent Key
without super lock), DLK-420, "
DOOR LOCK AND UNLOCK SWITCH : Symptom Table" (with
Intelligent Key and super lock), DLK-567, "
DOOR LOCK AND UNLOCK SWITCH : Symptom
Table" (without Intelligent Key without super lock) or DLK-718, "DOOR LOCK AND UNLOCK
SWITCH : Symptom Table" (without Intelligent Key with super lock).
2. CHECK ENGINE STARTING
1. Checks that the engine starts.
Does the engine start?
YES >> GO TO 3
NO >> Refer to SEC-76, "
Symptom Table" (with Intelligent Key) or SEC-117, "Symptom Table" (without
Intelligent Key).
3. CHECK STEERING LOCKING (MODELS WITH INTELLIGENT KEY)
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 STC-29, "
Symptom Chart".
4. 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-75, "
Symptom Table" (with Intelligent Key) or SEC-116, "Symptom Table" (without
Intelligent Key).
