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.

ler ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new key-
fobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. 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 additional code is registered, only the oldest code is erased. If less
than five ID codes are stored in memory, when an additi onal ID code is registered, the new ID code is added
and no ID codes are erased.
• If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.
• Entry of maximum five ID codes is allowed. When mo re than five ID codes are entered, the oldest ID code
will be erased.
• Even if same ID code that is already in the memory is input, the same ID code can be entered. The code is
counted as an additional code.

AUTOMATIC BACK DOOR SELF-DIAGNOSIS PROCEDURE
Self-Diagnosis ProcedureINFOID:0000000005146997
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 selector lever 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 selector lever 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.

INTELLIGENT KEY UNIT POWER BACK DOOR INPUT SIGNAL
INTELLIGENT KEY UNIT POWER BACK DOOR INPUT SIGNAL
DescriptionINFOID:0000000005147010
Carrying the Intelligent Key, enables the driver to open the liftgate using the back door handle even when the
vehicle is locked. When lifting the handle, the back door
handle switch sends this signal to the Intelligent Key
unit which treats it as a request switch signal. When t he Intelligent Key unit, using the rear bumper antenna,
validates the presence of the Intelligent Key, it s ends an open signal to the back door control unit regardless
whether the vehicle is locked.
Rear bumper antenna is mounted on the rear bumper and is used to allow the back door handle opening of
the locked back door when the Intelligent Key is present.
Diagnosis ProcedureINFOID:0000000005147011
Regarding Wiring Diagram information, refer to DLK-199, "Wiring Diagram—AUTOMATIC BACK DOOR SYS-
TEM—".
1.BACK DOOR HANDLE SWITCH SIGNAL INSPECTION
With all doors unlocked, check the back door handle operation by lifting the handle.
Did the back door respond correctly by opening?
YES >> GO TO 2
NO >> Refer to DLK-140, "
Diagnosis Procedure".
2.KEYFOB SIGNAL INSPECTION
Check keyfob operation using lock and unlock buttons.
Did the keyfob respond correctly?
YES >> GO TO 3
NO >> Refer to DLK-106, "
Diagnosis Procedure".
3.INTELLIGENT KEY UNIT SIGNAL INSPECTION
NOTE:
Since the diode is a uni-directional component, pay close attention to the polarity of the ohmmeter
being used as the presence of a diode in the circuit will affect the result.
1. Turn ignition switch OFF.
2. Disconnect Intelligent Key unit, back door handle switch and back door control unit connectors.
3. Check continuity between Intelligent Key unit connector (A) M70 terminal 29 and back door handle switch connector (B) D706
terminal 3.
4. Check continuity between Intelligent Key unit connector (A) M70 terminal 29 and ground.
Is the inspection result normal?
YES >> Replace the Intelligent Key unit.
NO >> Repair or replace the harness or the diode as necessary. 29 (+) - 3 (-) : Continuity should exist.
29 (+) - Ground (-) : Conti
nuity should not exist.
