Mirror Fold

Mirror Fold

A non-latching mirror folding switch is located on the drivers door module. When the switch is pressed a first time, the drivers door module (C2271) provides a feed to the mirror fold motor on an RU wire. Current flows across the motor and back to the drivers door module (C2271) on a GN wire. The drivers door mirror now moves to the folded position. If the switch is pressed a second time, the feed to the fold motor is reversed. The motor is provided a feed on a GN wire, with an earth path provided by the drivers door module (C2271) via an RU wire.

NOTE: Mirror fold is disabled if vehicle speed is greater than 10 km/h (6 mph).

The drivers door module (C2058) communicates the mirror fold request to the passenger door module (C2057) via the P-bus on a UR wire.

Mirror Heater

If the BCU (C0660) receives an outside temperature reading of between -10 °C and 35 °C, it informs the drivers door module (C2058) to initiate mirror heating via the P-bus on a UR wire. Pin 7 of the drivers door module (C2271) provides a feed to the door mirror heater on a B wire. An earth path is provided via pin 6 of the drivers door module (C2271), also on a B wire.

Passenger Door Mirror Horizontal Adjustment

When RH adjustment of the passenger door mirror is required, the passenger door module (C2271) provides a feed to the horizontal motor on a G wire. Current flows across the motor and back to the passenger door module (C2271) on an R wire. If LH adjustment of the passenger door mirror is required, the feed to the horizontal motor is reversed. The motor is provided a feed on an R wire, with an earth path provided by the passenger door module (C2271) via a G wire.

To prevent the vertical motor from operating, the passenger door module (C2271) also provides a feed to the vertical motor on an S wire. As the potential difference across the motor is 0V, the motor does not operate.

Vertical Adjustment

When upwards adjustment of the passenger door mirror is required, the passenger door module (C2271) provides a feed to the vertical motor on an S wire. Current flows across the motor and back to the passenger door module (C2271) on an R wire. If downwards adjustment of the passenger door mirror is required, the feed to the vertical motor is reversed. The motor is provided a feed on an R wire, with an earth path provided by the passenger door module (C2271) via an S wire.

To prevent the horizontal motor from operating, the passenger door module (C2271) also provides a feed to the horizontal motor on a G wire. As the potential difference across the motor is 0V, the motor does not operate.
