System DescriptionINFOID:0000000003766890
 Traction Control System is a function that electronically controls engine torque, brake fluid pressure and
CVT shift position 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 (rear
wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid pres-
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.

 Electric Brake force Distribution is a following function. ABS actuator and electric unit (control unit) detects
subtle slippages between the front and rear wheels during braking. Then is electronically controls the rear
braking force (brake fluid pressure) to reducing and reduces rear wheel slippage. Accordingly it improves
vehicle stability.
 Electrical system diagnosis by CONSULT-III is available.

FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
WORK SUPPORT
SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
Display Item List
Refer to BRC-140, "DTC No. Index".
How to Erase Self-diagnosis Results
After erasing DTC memory, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
 When the wheel sensor malfunctions, after inspecting the wheel sensor system, ABS warning lamp, VDC
OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is
normal unless the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
 Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or in case of brake
fluid level switch operation (when brake fluid is insufficient).
 VDC OFF switch should not stay in “ON” position.
