Operation
Signals from the ETC control module (N15/3) are converted into hydraulic functions in the electric valve
control unit (Y3/6). The RPM sensors (Y3/6n2, Y3/6n3), the starter lockout contact (Y3/6s1) and the
transmission oil temperature sensor (Y3/6b1) of the electrical control unit (Y3/6) supply the ETC control
module (N15/3) with input signals. The solenoid valves are controlled by the ETC control module (N15/3) and
trigger the hydraulic functions. See Fig. 36.
