Nissan Cube Z12 Series Traction Control Wiring System. Traction Control System is a function that electronically controls engine torque, brake fluid pressure and A/T gear position to ensure the optimum slippage ratio at drive wheels by computing wheel speed signals from 4 wheel sensors. The following schematic shows the Nissan Cube Z12 Series Traction Control Wiring System Diagram.
When ABS actuator and electric unit (control unit) detects a spin at drive wheels (rear wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid pre sure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine torque by the control unit.
Further more, throttle position is continuously controlled to ensure the optimum engine torque at all times. During TCS operation, TCS informs driver of system operation by flashing SLIP indicator lamp. Electrical system diagnosis by CONSULT-III is available.
