CHECK OUTPUT SIGNAL OF TCM.

Return the engine to idling speed and shift the select lever to “N” range.

NOTE:

The speed difference between front and rear wheels lights the ABS warning light or the VDC warning light, but this does not indicate a malfunction. If the warning light is illuminated, clear the memory of ABS or VDC after completing AT control diagnosis.

QUESTION

Is the measured value 100%?

Yes No

Check the harnesses or connectors between TCM and transmission, and repair the defective part.
