DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK VDCCM&H/U GROUND 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 Models without EyeSight (B310) No. 38 - Chassis ground: Models with EyeSight (B310) No. 34 - 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.	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 OTHER DTC DETECTION.	Is any other DTC displayed?	Perform the diagnosis according to DTC. < Ref. to LIST OF DIAGNOSTIC TROUBLE CODE (DTC) . >	Temporary poor contact occurs.
