WARNING: This page is about a different car, the 2004 Mercedes-Benz C230 and 2003 Mercedes-Benz C230. However, it is still accessible from the selected car via links, so may be relevant.
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 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.
