CHECK OUTPUT SIGNAL FROM TCM USING SUBARU SELECT MONITOR.

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

NOTE:

The speed difference between front and rear wheels may illuminate the ABS warning light, but this does not indicate a malfunction. When AT control diagnosis is finished, perform the ABS or VDC clear memory of on-board diagnostics system.

QUESTION

Is the measured value 100%?

Yes No

Even if the power indicator light is blinking, the circuit is in normal condition at this time. A temporary poor contact of connector or harness may be the cause. Repair the harness or connector in TCM and transmission.
