1. CHECK VDCCM&H/U INPUT VOLTAGE  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the connector from the VDCCM&H/U.
   3. Run the engine at idle.
   4. Measure the voltage between VDCCM&H/U connector and chassis ground.

      Connector and terminal 

      (B310) No. 1 (+) - Chassis ground (-):

      (B310) No. 30 (+) - Chassis ground (-):

      (B310) No. 35 (+) - Chassis ground (-):

   Is the voltage 10 - 15 V?

   Yes:  Go to  2.

   No:  Repair the power supply circuit including the battery.

2. CHECK VDCCM&H/U GROUND CIRCUIT (CHECK FOR OPEN CIRCUIT)  .
   1. Turn the ignition switch to OFF.
   2. Measure the resistance between VDCCM&H/U connector and chassis ground.

      Connector and terminal 

      (B310) No. 14 - Chassis ground:

   Is the resistance less than 10 Ω?

   Yes:  Go to  3.

   No:  Repair the VDCCM&H/U ground harness.

3. CHECK POOR CONTACT OF CONNECTORS  .

   Is there poor contact of connector between generator, battery and VDCCM&H/U?

   Yes:  Repair the connector.

   No:  Go to  4.

4. CHECK VDCCM&H/U  .
   1. Connect all connectors.
   2. Using the Subaru Select Monitor, perform the clear memory. Ref. to COMMON (diag)>CLEAR MEMORY .
   3. Execute the inspection mode. Ref. to BRAKE CONTROL (DIAGNOSTICS)>INSPECTION MODE .
   4. Read the DTC using Subaru Select Monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) .

   Is the same DTC displayed?

   Yes:  Replace the VDCCM&H/U. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM&H/U) .

   No:  Go to  5.

5. CHECK DETECTION OF OTHER DTCS FOR VDC  .

   Read the DTC using Subaru Select Monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) .

   Is any other DTC displayed?

   Yes:  Perform the diagnosis according to DTC. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Diagnostic Trouble Code (DTC)>LIST .

   No:  Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference.
