ID Code Entry ProcedureBIS000WW
KEY FOB ID SET UP WITH CONSULT-II
NOTE:

If a key fob is lost, the ID code of the lost key fob must be erased to prevent unauthorized use. A
specific ID code can be erased with CONSULT-II. However, when the ID code of a lost key fob 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 key fobs must be re-registered.

When registering an additional key fob, 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 old-
est code is erased. If less than five ID codes are stored in memory, when an additional ID code is
registered, the new ID code is added and no ID codes are erased.

Entry of maximum five ID codes is allowed. When more than six 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.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.
