REMOTE KEYLESS ENTRY SYSTEM
Revision: November 20092006 QX56
NOTE:

If a keyfob is lost, the ID code of the lost keyfob 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 keyfob is not known, all con-
troller 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.
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 additional 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 more 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.

diagnostic test item Diagnostic mode
Description
Inspection by part WORK SUPPORT
Supports inspections and adjustments. Commands are transmitted to the
BCM for setting the status suitable for required operation, input/output sig-
nals are received from the BCM and received date is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to
them.
SELF-DIAG RESULTS Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be
read.
ECU PART NUMBER BCM part number can be read. CONFIGURATION Performs BCM configuration read/write functions.
