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

      Connector & terminal 

      (B66) No. 1 (+) - Chassis ground (-):

      (B66) No. 30 (+) - Chassis ground (-):

      (B66) No. 36 (+) - Chassis ground (-):

   Is the voltage 10 - 15 V?

   Yes  : Go to  2.

   No  : Repair the power supply circuit including the battery.

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

      Connector & terminal 

      (B66) No. 14 - Chassis ground:

      (B66) No. 46 - Chassis ground:

   Is the resistance less than 10 Ω?

   Yes  : Go to  3.

   No  : Repair the VDC Control Module & H/U ground harness.

3. CHECK POOR CONTACT OF CONNECTORS  .

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

   Yes  : Repair the connector.

   No  : Go to  4.

4. CHECK VDC Control Module & H/U  .
   1. Connect all connectors.
   2. Using the Subaru Select Monitor, perform the clear memory of [Brake Control]. Ref. to COMMON (DIAGNOSTICS)>CLEAR MEMORY
   3. Execute the inspection mode. Ref. to BRAKE CONTROL (DIAGNOSTICS)>INSPECTION MODE 
   4. Read the DTC of [Brake Control] using the Subaru Select Monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) 

   Is the same DTC displayed?

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

   No  : Go to  5.

5. CHECK DETECTION OF OTHER DTCS FOR VDC  .

   Read the DTC of [Brake Control] using the Subaru Select Monitor. Ref. to BRAKE CONTROL (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) 

   Is any other DTC displayed?

   Yes  : Perform the diagnosis according to the 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.
