through 10A fuse [No. 19, located in the fuse block (J/B)]

to key switch and key lock solenoid terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
Serial data is supplied

to BCM terminal 22

through main power window and door lock/unlock switch terminal 14.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns the interior room lamps ON for 30 sec-
onds.
Key is in ignition key cylinder (key switch ON), power is supplied

through key switch and key lock solenoid terminal 4

to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), power supply to BCM terminal
37 is terminated. BCM detects that key has been removed, determines that interior room lamp and map lamp
timer conditions are met, and turns the interior room lamps ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM determines
that conditions for interior room lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.

Front door LH is locked [when locked by keyfob, main power window and door lock/unlock switch, or front
door lock assembly LH (key cylinder switch)]

Front door LH is opened (front door switch LH turns ON)

Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If interior lamp is left “ON”, it will not be turned off even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls interior lamps listed below:

Va n i t y l a m p

Room/map lamp

Cargo lamp

Personal lamp

St ep la m ps

Puddle lamps

Foot lamps

Ignition keyhole illumination
After lamps turn OFF by the battery saver system, the lamps illuminate again when

signal received from keyfob, or main power window and door lock/unlock switch or front door lock assem-
bly LH (key cylinder switch) is locked or unlocked

door is opened or closed

key is removed from ignition key cylinder (key switch OFF) or inserted in ignition key cylinder (key switch
ON).
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II.

All Interior Room Lamps Do Not OperateEKS00BBG
1. CHECK POWER SUPPLY CIRCUIT
1. All interior room lamp switches are OFF.
2. Turn ignition switch ON.
3. Check voltage between BCM harness connector M20 terminal 56 and ground.
OK or NG
OK >> Repair harness or connector. To prevent making a short circuit, be sure to disconnect battery negative cable
after repairing harness, and then reconnect.
NG >> Replace BCM. Refer to BCS-20, "
BCM" .
Ignition Keyhole Illumination Control Does Not OperateEKS00BBH
1. CHECK EACH SWITCH
Select "BCM" on CONSULT-II. With "INT LAMP" data monitor, make
sure switches listed in display item list turn ON-OFF linked with
switch operation. Refer to LT- 1 5 1 , "
Display Item List" for switches
and their functions.
OK or NG
OK >> GO TO 2.
NG >> Inspect malfunctioning switch system.
2. ACTIVE TEST
1. Select "BCM" on CONSULT-II. Select "INT LAMP".
2. Select "IGN ILLUM" active test to make sure lamp operates.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "BCM" .

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery post and terminals, reconnect them and restart the
test.
3. Connect the red tester lead clamp to the positive battery termi- nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys, select “IN-VEHICLE” on the tester and then press the “ENTER ”
key.
5. Locate the battery type and rating stamped or written on the top case of the battery to be tested.
NOTE:
The battery rating will be either of the following:

CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)

JIS: Japanese Industrial Standard.
When using the Battery Tester use the CCA rating only.

The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.

(U.S. market) Refer to the latest "Battery Testing" Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.

You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA.
7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to SC-8, "

AUTOMATIC DRIVE POSITIONER
Revision: November 20092006 QX56
System DescriptionEIS004XE

Refer to Owner's Manual for Automatic Drive Positioner system operating instructions.

The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display control unit to driver seat control unit.

Using CONSULT-ll, the seat slide amount at entry/exit setting can be changed.
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open) →OFF (close) →ON
(open), the Entry/Exiting function becomes possible.

After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON →START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
FAIL-SAFE MODE
When any manual and automatic operations are not performed, if any motor operations of seats or pedals are
detected for T2 or more, status is judged “Output error ”.
