Door lock indicator timer
Door lock indicator timer is designed to reacts and shut down the indicator. The default timer values are 1
minute and 30 minutes.
lWhen the lock operation is activated by keyfob or auto door lock (for further details, refer toBL-92, "Auto
Re-lock Function"), then the illuminate time is set to 1 minute.
lWhen the lock operation is activated by door lock/unlock switch, then the timer is set to 30 minutes.
NOTE:
When the 30 minutes timer is active and ignition switch is turned ON, the indicator illuminate for perma-
nently, unless ignition switch is turned OFF then timer will be reset back to 30 minutes.
CAN Communication System DescriptionEIS00D7T
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitEIS00D7U
Refer toLAN-23, "CAN COMMUNICATION".

CONSULT-II BASIC OPERATION PROCEDURE
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
data link connector.
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, go toGI-50, "
