System Description

INFOID:0000000000924800

• Traction Control System is a function that electronically controls engine torque, brake fluid pressure and

gear ratio (except M/T) to ensure the optimum slippage ratio at drive wheels by computing wheel speed sig-
nals from 4 wheel sensors. 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
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-III is available.
