Check VDCCM

DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK VEHICLE SPEED SIGNAL. Lift up the vehicle and support it with rigid racks. Drive the vehicle faster than 10 km/h (6 MPH). WARNING: Be careful not to be dragged in by the rotating wheel. Measure the voltage between combination meter connector and chassis ground. Connector & terminal (i10) No. 27 (+) - Chassis ground (-):	Is the voltage less than 1 V ←→ 5 V or more?	Replace the meter case assembly.	Go to step 2 .
2 CHECK HARNESS BETWEEN VDCCM AND COMBINATION METER. Turn the ignition switch to OFF. Disconnect the connector from VDCCM and combination meter. Measure the resistance between VDCCM harness connector and combination meter harness connector. Connector & terminal (B310) No. 10 - (i10) No. 27:	Is the resistance less than 10 Ω?	Check the VDCCM. Refer to CLEAR MEMORY MODE .	Repair the wiring harness.
