TCS Sequence Control
TCS Sequence Control1) Under the TCS sequence control, after the hydraulic unit solenoid valve is driven, the operation of the hydraulic unit can be checked by means of the brake tester or pressure gauge.
2) TCS sequence control can be started by diagnosis connector or select monitor.
Operational Guidelines Of The TCS Sequence Control With Diagnoses Connector
1) Connect diagnosis terminals to terminal No.4 of the diagnosis connector beside driver seat heater unit.
2) Ignition switch is turned to ON.
3) Make sure only the start code (code 11) is shown in normal condition.
NOTE: When trouble codes are stored in memory, repair the faulty parts.
4) Set the speed of all wheels at 10 km/h (6 MPH) or less.
5) Turn ignition switch OFF.
6) Start engine, and within 0.5 seconds after the ABS warning light and TCS warning light go out, press 105 OFF switch. Within 1.0 second thereafter, release and press the switch again. Then, keep the switch pressed.
NOTE:
- When the TCS sequence control is set to on, the brake pedal must not be depressed.
- Engine must operate.
- When TCS OFF switch is not depressed within 0.5 seconds after ABS and TCS warning lights turn off, the trouble code mode comes on.
7) After completion of TCS sequence control, turn ignition switch OFF.
Operational Guidelines Of The TCS Sequence Control With Select Monitor
1) Connect select monitor to data link connector beside driver's seat heater unit.
2) Engine starts.
3) Put select monitor to TCS mode.
4) Put select monitor to FBI mode. Make sure code 11 is indicated.
NOTE; When trouble codes are stored in memory, repair the faulty parts.
5) Press FD2 ENT key.
6) When the message shown in the figure is displayed, press ENT key.
7) Checked portions will be displayed on select monitor.
8) When TCS sequence control cannot be started (by system malfunction, etc.), the message shown in the figure will be displayed.
NOTE: Read the trouble codes. Repair faulty parts.
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 monitor 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.
Conditions For TCS Sequence Control
NOTE: When select monitor is used, control operation starts at point A. It is not required to operate TCS OFF switch for starting control operation. The patterns from IGN key ON to point A show operation is started by diagnosis connector.
