1. While the ABS sequence control is being performed, the operation of the hydraulic unit can be checked using the brake tester or pressure gauge after the hydraulic unit solenoid valve operation.
2. ABS sequence control can be started by the Subaru Select Monitor.
1. ABS SEQUENCE CONTROL WITH SUBARU SELECT MONITOR
NOTE:
In the event of any trouble, the ABS sequence control will not operate.
1. Connect the Subaru Select Monitor to data link connector under the driver’s side instrument panel lower cover.
2. Turn the ignition switch to ON.
3. Run the “PC application for Subaru Select Monitor”.
4. Set the Subaru Select Monitor to “Brake Control System” mode.
5. When the “Function check sequence” is selected, the “ABS sequence control” will start.
6. Execute the following operations when the message “Press the brake pedal so that the brake pedal force is between 100 and 150 kgf” is displayed.
(1) When using a brake tester, press the brake pedal pad with a force of 1,000 N (102 kgf, 225 lbf).
(2) When using a pressure gauge, press the brake pedal so that the pressure gauge indicates 3,500 kPa (36 kgf/cm2, 511 psi).
7. Press the [OK] after “Press OK” is displayed.
8. The brake system being operated is displayed on the Subaru Select Monitor.
