CHECK OUTPUT SIGNAL OF TCM.

1) Return the engine speed to idle.

2) Set the select lever to “N” range.

3) Read the data of “Lock Up Duty Ratio” using Subaru Select Monitor.

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.
