CHECK OUTPUT SIGNAL FROM TCM USING SUBARU SELECT MONITOR.

1) Lift up the vehicle and place it on rigid racks.

NOTE:

Raise all wheels off the floor.

2) Shift the select lever to “1” range. Slowly increase the vehicle speed up to 15 km/h (9 MPH), and then return the accelerator pedal.

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.

3) Read the data of the low & reverse duty solenoid.

QUESTION

Is the measured value 55%?

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.
