Step	Check	Yes	No
1 CHECK VDCCM & H/U GROUND CIRCUIT (CHECK FOR OPEN CIRCUIT). Turn the ignition switch to OFF. Disconnect the connector from the VDCCM & H/U. Measure the resistance between VDCCM & H/U and chassis ground. Connector & terminal (B310) No. 38 - 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. Connect all connectors. Perform the Clear Memory Mode. Ref. to CLEAR MEMORY MODE . Perform the Inspection Mode. Ref. to INSPECTION MODE . Read the DTC. Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) .	Is the same DTC displayed?	Replace the VDCCM only. Ref. to REPLACEMENT , 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 temporary poor contact in the harness and connector or a temporary noise interference.
