Nissan Leaf. Manual - part 313

BRC-42

< SYSTEM DESCRIPTION >

[WITH VDC]

SYSTEM

• The electrically-driven intelligent brake unit transmits a brake warning lamp request signal to the ABS actua-

tor and electric unit (control unit) via CAN communication when detecting a malfunction in the electrically-

driven intelligent brake unit.

• The ABS actuator and electric unit (control unit) receiving a brake warning lamp request signal, and trans-

mits a brake system warning lamp signal to the combination meter via CAN communication.

• The combination meter turns ON the brake system warning lamp when receiving a brake system warning

lamp signal.

• For the relationship between warning lamp and DTC, refer to 

BR-38, "DTC Index"

.

LIGHTING CONDITION

When any of the condition listed below is satisfied while the power switch ON:

• Brake fluid level switch ON.

• Parking switch ON.

• A malfunction is detected in the EBD function of the ABS actuator and electric unit (control unit).

• A malfunction is detected in the electrically-driven intelligent brake unit.

• For the relationship between warning lamp and DTC, refer to 

BR-38, "DTC Index"

 (electrically-driven intelli-

gent brake unit) or 

BRC-56, "DTC Index"

 [ABS actuator and electric unit (control unit)].

SHUTOFF CONDITION

• When the condition listed below is satisfied while the power switch ON:

- Brake fluid level switch is OFF.

- Parking brake switch is OFF.

- Erase  DTC

• Power switch OFF

SIGNAL PATH

• The ABS actuator and electric unit (control unit) receives a VDC OFF switch signal from the VDC OFF

switch.

• The ABS actuator and electric unit (control unit) transmits a VDC OFF indicator lamp signal to the combina-

tion meter via CAN communication according to the received VDC OFF switch signal.

• The combination meter turns ON the VDC OFF indicator lamp when receiving a VDC OFF indicator lamp

signal.

LIGHTING CONDITION

When all of the condition listed below are satisfied:

• Power switch ON 

• VDC OFF switch ON (VDC function and TCS function non-operational status)

SHUTOFF CONDITION

• When the condition listed below is satisfied while the power switch ON:

- VDC OFF switch OFF (VDC function and TCS function standby status)

• Power switch OFF

[WITH VDC]

SYSTEM

• When VDC function, TCS function, or brake limited slip differential

(BLSD) function is activated, the VDC warning lamp blinks to

inform the driver of the activation of the function.

• When VDC function, TCS function, ABS function, EBD function,

brake limited slip differential (BLSD) function, or brake assist func-

tion of the ABS actuator and electric unit (control unit) has a mal-

function, the VDC warning lamp turns ON to warn the driver of the

malfunction.

NOTE:

The VDC warning lamp may turn ON when the brake warning lamp

or ABS warning lamp turns ON. For details, refer to 

BRC-16, "Sys-

tem Description"

.

BULB CHECK

The VDC warning lamp turns ON and stays ON for approximately one second after turning ON the power

switch.

SYNCHRONIZATION WITH MASTER WARNING LAMP

OPERATION AT COMBINATION METER CAN COMMUNICATION CUT-OFF OR UNUSUAL SIG-
NAL

For actions on CAN communications blackout in the combination meter, refer to

*: For DTCs that the VDC warning lamp turns ON, refer to 

BRC-56, "DTC Index"

.

SIGNAL PATH

When Operating VDC Function, TCS Function, Brake Limited Slip Differential (BLSD) Function:

• The ABS actuator and electric unit (control unit) transmits a VDC warning lamp signal to the combination

meter via CAN communication when operating in the VDC function, TCS function, or brake limited slip differ-

ential (BLSD) function.

• The combination meter blinks the VDC warning lamp when receiving a VDC warning lamp signal.

When VDC Function, TCS Function, Brake Limited Slip Differential (BLSD) Function, Brake Assist Function Are In
Abnormal State:

• The ABS actuator and electric unit (control unit) transmits a VDC warning lamp signal to the combination

meter via CAN communication when detecting a malfunction in the VDC function, TCS function, brake lim-

ited slip differential (BLSD) function, or brake assist function.

• The combination meter turns ON the VDC warning lamp when receiving a VDC warning lamp signal.

• For the relationship between warning lamp and DTC, refer to 

BRC-56, "DTC Index"
