TRANSIT MODE CANCEL OPERATION

TRANSIT MODE CANCEL OPERATION

Description

INFOID:0000000007565037

• BCM is in transit mode if turn signal indicator on combination meter turns ON for 1 minute when ignition

switch is turned from OFF to ON.

• In this case, cancel operation must be performed.
NOTE:
Do not cancel transit mode during storage of the vehicle. Always cancel transit mode before delivery of the
vehicle to customer.

Work Procedure

INFOID:0000000007565038

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM

Description

INFOID:0000000007565039

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, 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.

NORMAL OPERATING CONDITION

Description

INFOID:0000000007818549

TRANSIT MODE

• Transit mode inhibits battery power consumption during transportation or storage of the vehicle.
• BCM is set to transit mode before delivery.
• In transit mode, remote keyless entry function, headlamp ON/OFF function, theft warning alarm function,

and other BCM control functions do not operate normally.

• Therefore, cancel operation must be performed so that the vehicle is used in normal status.
• For transit mode cancel operation, refer to

BCS-64, "Description"

NOTE:
Do not cancel transit mode during storage of the vehicle. Always cancel transit mode before delivery of the
vehicle to customer.
