ID Code Entry ProcedureINFOID:0000000003775799
KEYFOB ID SET UP WITH CONSULT-III
NOTE:
•
If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A spe-
cific ID code can be erased with CONSULT-III. Ho wever, when the ID code of a lost keyfob is not
known, all controller ID codes should be erased. After all ID codes are erased, the ID codes of all
remaining and/or new keyfobs must be re-registered.
• When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If
five ID codes are stored in memory when an additi onal code is registered, only the oldest code is
erased. If less than five codes are stored in memory when an additional code is registered, the new
ID code is added and no ID codes are erased.
• Entry of a maximum of five ID codes is allowed. Wh en more than five codes are entered, the oldest ID
code will be erased.
• Even if the same ID code that is already in memory is input, the same ID code can be entered. The
code is counted as an additional code.
1. Turn ignition switch ON.
2. Select “BCM”.
3. Select “MULTI REMOTE ENT”.
4. Select “WORK SUPPORT”.
5. You can register, erase or confirm a keyfob ID code. To register a new code, select the following option
and follow CONSULT-III instructions:
• “REMO CONT ID REGIST” Use this mode to register a keyfob ID code.
NOTE:
Register the ID code when keyfob or BCM is re placed, or when additional keyfob is required.
• “REMO CONT ID ERASUR” Use this mode to erase a keyfob ID code.
• “REMO CONT ID CONFIR”
Use this mode to confirm if a ke yfob ID code is registered or not.

AUTOMATIC BACK DOOR SELF-DIAGNOSIS PROCEDURE
Self-Diagnosis ProcedureINFOID:0000000003775801
INPUT SIGNAL CHECK MODE
Input signal check mode allows testing of swit ch input signal to the back door control unit.
To activate input signal check mode on the automatic sliding door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T shift selector in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
8. Release the back door handle switch.
9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
11. Release the power liftgate switch.
12. The input signal check mode is now initialized.
The input signal check mode can test the following inputs. The back door warning chime will sound for approx-
imately 0.5 second each time a switch signal input oc curs. Use this test when one of these inputs is not
responding during normal automatic back door operation.
*Back door warning chime should sound as soon as vehicle moves.
Turn ignition switch OFF to end input signal check mode.
OPERATING CHECK MODE
Operating check mode allows self-diagnos is of the automatic back door system.
To activate operating check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T shift selector in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 second.
8. Release the back door handle switch.

TURN SIGNAL AND HA ZARD WARNING LAMPS

TURN SIGNAL OPERATION
When the turn signal switch is in LH or RH position with the ignition switch in ON position, the BCM detects the
TURN RH or TURN LH ON request. The BCM outputs the fl asher signal to the respective turn signal lamp.
The BCM also sends a turn indicator signal ON reques t via the CAN communication lines to the combination
meter. The combination meter then activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazar d indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combinati on meter then activates the hazard indicator and audible
buzzer.
REMOTE KEYLESS ENTRY OPERATION
The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard
lamps.
Refer to SEC-7, "
System Description".

INTERIOR ROOM LAMP CONTROL SYSTEM
System DiagramINFOID:0000000003776239
System DescriptionINFOID:0000000003776240
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Front room/map lamps, personal lamp 2nd row, personal lamp 3rd row (when lamp switch is in DOOR posi-
tion) and puddle lamps.
• Cargo lamp is controlled by the cargo lamp control function of the BCM.
• Step lamps* are controlled by the step lamp control function of the BCM. *Front step lamps, rear step lamps and foot lamps.
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 switc hes or the key switch and ignition knob switch.
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 ignition switch.
Timer control is cancelled 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).
• Ignition switch is turned ON.
Interior lamp operational settings can be c hanged with the function setting of CONSULT-III.
