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 

      Models without EyeSight 

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

      (B310) No. 6 (+) - Chassis ground (-):

      (B310) No. 25 (+) - Chassis ground (-):

      Models with EyeSight 

      (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 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 

      Models without EyeSight 

      (B310) No. 13 - Chassis ground:

      Models with EyeSight 

      (B310) No. 14 - 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. Perform the Clear Memory Mode. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>CLEAR MEMORY MODE .
   3. Perform the Inspection Mode. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>INSPECTION MODE .
   4. Read the DTC. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>READ DIAGNOSTIC TROUBLE CODE (DTC) .

   Is the same DTC displayed?

   Yes:  Replace the VDC Control Module & H/U. Refer 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. 

   Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>READ DIAGNOSTIC TROUBLE CODE (DTC) .

   Is any other DTC displayed?

   Yes:  Perform the diagnosis according to DTC. Refer to VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)>LIST OF DIAGNOSTIC TROUBLE CODE (DTC) .

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