ABS Sequence Control
ABS Sequence ControlOPERATION
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 Subaru Select Monitor.
ABS SEQUENCE CONTROL WITH DIAGNOSIS CONNECTOR
1) Turn the ignition switch to OFF.
2) Connect the diagnosis terminal to terminal No. 6 of the diagnosis connector beside driver's seat.
3) Turn the ignition switch to ON.
4) Confirm that start code (code 11) is only displayed.
5) Turn the ignition switch to OFF.
6) Connect the diagnosis terminals to terminals No. 6 and No. 3 of the diagnosis connector.
7) Set the speed of all wheels at 4 km/h (2 MPH) or less.
8) Turn the ignition switch to ON.
9) Within 0.5 seconds after the ABS warning light goes out, depress the brake pedal and hold it depressed.
NOTE:
^ Engine must not operate.
CAUTION: Do not depress the clutch pedal in case of vehicle with hill holder.
10) After completion of ABS sequence control, turn the ignition switch to OFF.
ABS SEQUENCE CONTROL WITH SUBARU 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".
^ When the diagnosis terminal is connected to the diagnosis connector, the sequence control will not operate.
1) Connect the Subaru Select Monitor to data link connector under driver's seat instrument panel lower cover.
2) Turn the ignition switch to ON.
3) Turn the Subaru Select Monitor switch to ON.
4) Put the Subaru Select Monitor to "BRAKE CONTROL" mode.
5) When "Function check sequence" is selected, "ABS sequence control" will start.
6) When the message "Press Brake Pedal Firmly" is displayed, perform the followings.
1) When using the brake tester, depress the brake pedal with braking force of 981 N (100 kgf, 221 lbs.).
2) When using the pressure gauge, depress the 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 in case of vehicle with hill holder.
7) When the message "Press YES" is displayed, press the YES key.
8) The braking system in operation is displayed on Subaru Select Monitor.
CONDITIONS FOR ABS SEQUENCE CONTROL
NOTE:
^ When the Subaru Select Monitor is used, control operation starts at point A. The patterns from IGN key ON to the point A show that operation is started by diagnosis connector. (However, the brake light switch must be ON before point A.)
^ HIGH means high voltage.
^ LOW means low voltage.
SPECIFICATION

3) When the brake pedal is released during sequence control and the braking lamp switch is set to off.
4) When the brake pedal is depressed after ignition key is turned to ON, and before ABS warning light goes out. (When the Subaru Select Monitor is not used.)
5) When the brake pedal is not depressed after ignition key is turned to ON, and within 0.5 seconds after ABS warning light goes out. (When the Subaru Select Monitor is not used.)
