Diagnosis Procedure

1.CHECK ELECTRIC SHIFT CONTROL MODULE INPUT VOLTAGE

With M.U.T.-III SE

The ignition switch is ON.
Select “Data List” in “SHIFT”.
Select “Shift sensor 1 voltage”, “Shift sensor 2 voltage”, “Shift sensor 3 voltage”, “Shift sensor 4 voltage”, “Shift sensor 5 voltage”, “Shift sensor 6 voltage”, “Shift sensor 7 voltage”, and “Shift sensor 8 voltage”.

Operate the selector lever and check the voltage.
