System Description

SYSTEM DIAGRAM

Wheel spin status of drive wheel is detected by wheel sensor of 4 wheels. Engine output and transmission shift status are controlled so that slip rate of drive wheels is in appropriate level. When wheel spin occurs on drive wheel, ABS actuator and electric unit (control unit) performs brake force control of LH and RH drive wheels (applies brake force by increasing brake fluid pressure of drive wheel) and decreases engine torque by engine torque control. Wheel spin amount decreases. Engine torque is controlled to appropriate level.
TCS function can be switched to non-operational status (OFF) by operating VDC OFF switch. In this case, VDC OFF indicator lamp turns ON.
VDC warning lamp blinks while TCS function is in operation and indicates to the driver that the function is in operation.
CONSULT can be used to diagnose the system diagnosis.
Fail-safe function is adopted. When a malfunction occurs in TCS function, the control is suspended for VDC function, TCS function, brake assist function and hill start assist function. The Nissan Murano vehicle status becomes the same as models without VDC function, TCS function, brake assist function and hill start assist function. However, ABS function and EBD function are operated normally. Refer to Fail-Safe.

SIGNAL TRANSMISSION FUNCTION LIST

Major signal transmission between each unit via communication lines is shown in the following table:

Component	Signal description
ECM	Mainly transmits the following signals to ABS actuator and electric unit (control unit) via CAN communication: Accelerator pedal position signal Brake pedal position signal Engine speed signal Engine torque signal Mainly receives the following signal from ABS actuator and electric unit (control unit) via CAN communication: Engine torque request signal
TCM	Mainly transmits the following signal to ABS actuator and electric unit (control unit) via CAN communication: Current gear position signal
Combination meter	Mainly receives the following signals from ABS actuator and electric unit (control unit) via CAN communication: Brake fluid level switch signal Parking brake switch signal Mainly receives the following signals from ABS actuator and electric unit (control unit) via CAN communication: VDC warning lamp signal VDC OFF indicator lamp signal
Steering angle sensor	Mainly transmits the following signals to ABS actuator and electric unit (control unit) via CAN communication: Steering angle sensor signal Steering angle sensor malfunction signal

Vdc Function

System Description SYSTEM DIAGRAM Side slip or tail slip may occur while driving on a slippery road or intending urgent evasive driving. VDC function detects side slip status using each sensor when side slip or tail slip is about to occur and improves Nissan Murano vehicle stability by brake control and engine output control during driving...

Abs Function

System Description SYSTEM DIAGRAM By preventing wheel lock through brake force (brake fluid pressure) control that is electronically controlled by detecting wheel speed during braking, stability during emergency braking is improved so that obstacles can be easily bypassed by steering operation...
