2) Measure the resistance between
VDCCM&H/U connector and chassis ground.
Connector & terminal
(B310) No. 43— Chassis ground:
Is the resistance less than 0.5
Ω?
Go to step 3.Repair the
VDCCM&H/U
ground harness.
3CHECK PRESSURE SENSOR.
1) Connect the Subaru Select Monitor to the
vehicle.
2) Select {Current Data Display & Save} in
Subaru Select Monitor.
3) Depress the brake pedal.
4) Read the pressure switch output in Subaru
Select Monitor.
Do the values on the monitor
display change when the pedal
is depressed?
Go to step 4.Replace the
VDCCM&H/U.
