Measure the voltage between VDCCM & H/U connector and chassis ground. Connector & terminal (B310) No. 28 (+) - Chassis ground (-):	Is the voltage 10 - 15 V?	Go to step 2.	Repair the power supply circuit.
2 CHECK VDCCM & H/U GROUND CIRCUIT. Turn the ignition switch to OFF. Measure the resistance between VDCCM & H/U connector and chassis ground. Connector & terminal (B310) No. 25 - Chassis ground:	Is the resistance less than 0.5 Ω?	Go to step 3.	Repair the VDCCM & H/U ground harness.
3 CHECK POOR CONTACT IN CONNECTORS.	Is there poor contact in connector between generator, battery and VDCCM & H/U?	Repair the connector.	Go to step 4.
4 CHECK VDCCM & H/U. Connect all connectors. Clear the memory. Refer to CLEAR MEMORY MODE . Perform the Inspection Mode. Refer to INSPECTION MODE . Read the DTC.	Is the same DTC displayed?	Replace the VDCCM & H/U. Refer to VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM & H/U) .	Go to step 5.
