Folding Mirror ECU

Fuse 16 of the passenger compartment fuse box (C0580) provides a constant battery feed to the folding mirror ECU (C0907) on a P then NS wire. The folding mirror ECU is located at the base of the passenger side 'A' post, and is earthed on a B wire.

The folding mirror ECU (C0907) monitors the condition of the door mirror switch (C0066) on a UB wire. When the switch is pressed, a momentary earth path is created on a B wire via the door mirror switch (C0066) and the passenger compartment fuse box (C0589 & C0587) on a B wire. When the folding mirror ECU senses this earth, it powers both folding mirror motors.
