DTC DETECTING CONDITION:

• Judge as malfunction when ECM internal malfunction is detected.

• This malfunction is stored if the fluid pressure request from the electronic parking brake does not operate.

TROUBLE SYMPTOM:

• ABS does not operate sometimes.

• EBD does not operate sometimes.

• VDC does not operate.

• Hill hold does not function.

• EyeSight does not operate. (Models with EyeSight)

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 --	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1411 ELECTRICAL CONTROL MODULE	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.	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1411 ELECTRICAL CONTROL MODULE
3.CHECK CAUSE OF SIGNAL NOISE.	Are the radio wave devices and electronic components installed correctly-	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1411 ELECTRICAL CONTROL MODULE	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.	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC C1411 ELECTRICAL CONTROL MODULE
5.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 C1411 ELECTRICAL CONTROL MODULE
6.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.
