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.
