1. Under the ABS 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. ABS sequence control can be started by diagnosis connector or select monitor.
ABS SEQUENCE CONTROL WITH DIAGNOSIS CONNECTOR
1. Connect diagnosis terminals to terminals No. 5 and No. 8 of the diagnosis connector beside driver's seat heater unit.
2. Set the speed of all wheels at 2.75 km/h (2 MPH) or less.
3. Turn ignition switch OFF.
4. Within 0.5 seconds after the ABS warning light goes out, depress the brake pedal and hold it immediately after ignition switch is turned to ON.
CAUTION: Do not depress the clutch pedal.
NOTE:
^ When the ignition switch is set to on, the brake pedal must not be depressed.
^ Engine must not operate.
5. After completion of ABS sequence control, turn ignition switch OFF.
ABS SEQUENCE CONTROL WITH SELECT MONITOR
NOTE:
^ In the event of any trouble, the sequence control may not be operative. In such a case, activate the sequence control, referring to "ABS SEQUENCE CONTROL WITH DIAGNOSIS CONNECTOR".

5. When "Function check sequence" is selected, ABS sequence control will start.
6. The message Press Brake Pedal Firmly' is displayed as follows:
1. When using the brake tester, depress brake pedal with braking force of 981 N (100 kgf, 221 lb).
2. When using the pressure gauge, depress brake pedal so as to make the pressure gauge indicate 3,432 kPa (35 kg/cm2, 498 psi).
CAUTION: Do not depress the clutch pedal.
7. When the message "Press YES" is displayed, press "YES" key.
