Nissan Maxima Service and Repair Manual: TCS
System Diagram
System Description
- Traction Control System is a function that electronically controls
engine torque and brake fluid pressure to
ensure the optimum slippage ratio at drive wheels by computing wheel speed
signals from 4 wheel sensors.
When ABS actuator and electric unit (control unit) detects a spin at drive wheels, it compares wheel speed signals from all 4 wheels. At this time, LH and RH front brake fluid pressure 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, it informs driver of system operation by flashing slip indicator lamp.
- Electrical system diagnosis by CONSULT is available.
