DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK VDCCM & H/U GROUND CIRCUIT (CHECK FOR OPEN CIRCUIT). 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from the VDCCM & H/U.
  3. Measure the resistance between VDCCM & H/U and chassis ground.

    Connector & terminal 

    (B310) No. 46 - Chassis ground: 

 Is the resistance less than 10 Ω? Go to step 2  . Repair the VDCCM & H/U ground harness.
2 CHECK POOR CONTACT OF CONNECTORS.  Is there poor contact of the connector between the battery, ignition switch and VDCCM & H/U? Repair the connector. Go to step 3  .
3 CHECK CAUSE OF SIGNAL NOISE.  Are the radio wave devices and electronic components installed correctly? Go to step 4  . Install the radio wave devices and electronic components properly.
4 CHECK CAUSE OF SIGNAL NOISE.  Is there a noise source (such as an antenna) installed near the sensor harness and VDCCM? Install the noise sources apart from sensor harness and VDCCM. Go to step 5  .
5 CHECK VDCCM & H/U. 
  1. Connect all connectors.
  2. Perform the Clear Memory Mode. < Ref. to CLEAR MEMORY MODE . >
  3. Perform the Inspection Mode. < Ref. to INSPECTION MODE . >
  4. Read the DTC. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >
 Is the same DTC displayed? Replace the VDCCM & H/U. < Ref. to VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM & H/U) . > Go to step 6  .
6 CHECK DETECTION OF OTHER DTCS FOR VDC. 
< Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >		 Is any other DTC displayed? Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . > Currently, it is normal. There may have been a poor contact in the harness and connector or a temporarily noise interference.
