3. CONDITIONS FOR COMPLETION OF TCS
SEQUENCE CONTROL
When the following conditions develop, the TCS sequence
control stops and ABS and TCS warning lights come on
while the ABS and TCS function will then stop. The brake
system functions as a conventional brake system.
1) When the speed of at least one wheel reaches 10 km/h
(6 MPH).
2) When terminal No. 4 is separated from ground. (When
select monitor is not used.)
3) When the brake pedal is depressed during sequence
control and the braking lamp switch is set to ON.
4) When TCS OFF switch is released. (When select moni-
tor is not used.)
5) After completion of the TCS sequence control.
6) When output signal to break TCS control is emitted from
ECM.
7) When malfunction is detected.
NOTE:
When malfunction has been detected and the TCS
sequence control operation has stopped, the trouble codes
are stored in memory.
