1. While the VDC sequence control is performed, the operation of the VDCH/U can be checked after operation of the VDCH/U solenoid valve, using the brake tester or pressure gauge.
2. VDC sequence control can be started by Subaru Select Monitor.
1. VDC SEQUENCE CONTROL WITH SUBARU SELECT MONITOR
1. Connect the Subaru Select Monitor to the Subaru data link connector, located next to the lower cover under the driver’s side instrument panel.
2. Turn the ignition switch to ON.
3. Set the Subaru Select Monitor switch to ON.
4. Set the Subaru Select Monitor to the “Brake Control” mode.
5. When the “VDC Inspection Mode” is selected from the “Function check sequence” menu, the “VDC sequence control” will start.
6. If “Press the YES key” is displayed, press the «YES» key.
7. The brake system being operated is displayed on the Subaru Select Monitor.
