KEYFOB ID SET UP WITH CONSULT

ID Code Entry Procedure

INFOID:0000000007355625

KEYFOB ID SET UP WITH CONSULT

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. However, 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 additional 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. When 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 instructions:

• “REMO CONT ID REGIST”

Use this mode to register a keyfob ID code.

NOTE:

Register the ID code when keyfob or BCM is replaced, 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 keyfob ID code is registered or not.
