Vehicle dynamics control system Ref. to WIRING SYSTEM>Vehicle Dynamics Control System .
- 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. 14 - Chassis ground:
Is the resistance less than 10 Ω?
- Yes : Go to 2.
- No : Repair the VDCCM&H/U ground harness.
- CHECK POOR CONTACT OF CONNECTORS.
Is there poor contact of the connector between the battery, ignition switch and VDCCM&H/U?
- Yes : Repair the connector.
- No : Go to 3.
- CHECK CAUSE OF SIGNAL NOISE.
Are the radio wave devices and electronic components installed correctly?
- Yes : Go to 4.
- No : Install the radio wave devices and electronic components properly.
- CHECK CAUSE OF SIGNAL NOISE.
Is there a noise source (such as an antenna) installed near the sensor harness and VDCCM?
- Yes : Install the noise sources apart from sensor harness and VDCCM.
- No : Go to 5.
- CHECK VDCCM&H/U.
- Connect all connectors.
- Clear the memory. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Clear memory .
- Perform the Inspection Mode. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Inspection Mode .
- Read the DTC. Ref. to BRAKE CONTROL (DIAGNOSTICS)>Read Diagnostic Trouble Code (DTC) .
Is the same DTC displayed?
- Yes : Replace the VDCCM only. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC Control Module and Hydraulic Control Unit (VDCCM&H/U)>REPLACEMENT .
- No : Go to 6.
- CHECK DETECTION OF OTHER DTCS FOR VDC.
Ref. to BRAKE CONTROL (DIAGNOSTICS)>Read Diagnostic Trouble Code (DTC) .
Is any other DTC displayed?
- Yes : Perform the diagnosis according to DTC. Ref. to BRAKE CONTROL (DIAGNOSTICS)>List of Diagnostic Trouble Code (DTC) .
- No : Currently, it is normal. There may have been a temporary poor contact in the harness and connector or a temporary noise interference.
