E3032 External mirrors adjustment (Euro3)

Description

The two external rear view mirrors are adjusted by the control on the central console between the seats, which is lit up when the side lights are on. The two mirrors are adjusted by a single button pressed in the four directions: a switch selects the right or left mirror.

The button, which can be pressed in four directions, controls two electric motors located in each of the two mirrors: one motor rotates the mirror on a horizontal axis, while the other on a vertical axis.

The adjustment circuit for the rear view mirrors is protected by the fuse which protects other supplies controlled by the ignition.

The mirrors can only be adjusted with the ignition switched ON.

Description of operation

The two-way switch controlling mirrors H30 operates electrical motors located in the right and left electrically-operated door mirrors P60 and P61 respectively.

The switch is supplied when the ignition is switched on (INT/A) at pin 2 of H30, by the line for F6 of the additional fuse box B98B ; pin 4 is earthed.

Operating the switch in one direction or the other, sends one of the two motors a positive and an earth signal, thereby determining the direction of rotation. The motors which adjust the vertical position are connected to pin 5 of the mirrors P60 and P61, the motors which adjust the horizontal position are connected to pin 3. According to the selector position, either the left motors (output signals from pins 6 and 8 of H30) or the right motors (output signals from pins 5 and 7 of H30) are connected; the common supply comes from pin 3 and is connected to pins 5 of the motors.

The switch H30 is lit up when the side lights are switched on by means of the line coming from the stalk unit switch H5 (pin 1).
