Functional description

The special front electric windows control unit M81 ensures the correct operation of the circuit. The direct supply from the battery reaches the control unit M81 (pin 30) from the line for the maxifuse J/B2 for B5 protected by fuse B22 , pin 31 provides the reference earth for the control unit. The control unit is then supplied at pin 15 from the line controlled by the ignition (INT) protected by fuse F8 for the junction unit B1 . The switches H40 (left electric window), H41 (right electric window in left front door) and H50 (right electric window in right front door) are supplied directly by the actual control unit, at pin 87 (common supply). There are two further connections, for the left electric window H40 , at pins P9 and P10 , which receive the command signals for the left front electric window motor N60 , operated by the control unit by pins M4 and M5. The right front electric window motor N61 is operated directly by the switches H41 and H50 , which provide suitable earth and supply signals to determine the direction of rotation of the motor. All the switches have specific LEDs which light up when they are supplied.
