1.CHECK VDCCM&H/U INPUT VOLTAGE. 1) Turn the ignition switch to OFF. 2) Disconnect the connector from the VDCCM&H/U. 3) Run the engine at idle. 4) Measure the voltage between VDCCM&H/U connector and chassis ground. Connector & terminal (B310) No. 5 (+) — (B310) No. 46 (−): (B310) No. 16 (+) — (B310) No. 46 (−): (B310) No. 33 (+) — (B310) No. 46 (−): | Is the voltage 10 — 15 V- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1362 NORMAL CLOSING VALVE 2 | Repair the power supply circuit. |
2.CHECK VDCCM&H/U GROUND CIRCUIT (CHECK FOR OPEN CIRCUIT). 1) Turn the ignition switch to OFF. 2) Measure the resistance between VDCCM&H/U connector and chassis ground. Connector & terminal (B310) No. 46 — Chassis ground: | Is the resistance less than 10 -- | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1362 NORMAL CLOSING VALVE 2 | Repair the VDCCM&H/U ground harness. |
3.CHECK POOR CONTACT OF CONNECTORS. | Is there poor contact of connector between generator, battery and VDCCM&H/U- | | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1362 NORMAL CLOSING VALVE 2 |
4.CHECK VDCCM&H/U. 1) Connect all connectors. 2) Perform the Clear Memory Mode. Clear Memory Mode 3) Perform the Inspection Mode. Inspection Mode 4) Read the DTC. Read Diagnostic Trouble Code (DTC) | Is the same DTC displayed- | Replace the VDCCM&H/U. VDC Control Module and Hydraulic Control Unit (VDCCM&H/U) | Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1362 NORMAL CLOSING VALVE 2 |
5.CHECK DETECTION OF OTHER DTCS FOR VDC. Read Diagnostic Trouble Code (DTC) | Is any other DTC displayed- | Perform the diagnosis according to DTC. 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. |
