DESCRIPTION AND OPERATION
RANGE ROVER 4.19
DOOR MIRRORS
DESCRIPTION
General
The door mirrors operate when the ignition switch is turned to the 'auxiliary' position.
Operation of the door mirrors is carried out by door modules located in each front door, in
conjunction with the Body Control Unit (BCU).
The BCU can store up to three mirror positions in its memory, which it transmits to the door
modules via the peripheral (P) bus. The BCU also initiates mirror heating if the outside
temperature is between -10 °C and 35 °C.
If reverse gear is selected, the passenger door mirror will automatically lower to enable the
driver to gain a better view of the kerb. When reverse gear is deselected, the mirror returns
to its original position.
For a detailed description of door mirror operation, refer to the Exterior Fittings – Door
Mirrors section of the Description and Operation Workshop Manual.
OPERATION
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fuse 11, fuse 24, and fuse 53
of the passenger compartment fuse box (C0632) on an R wire. Fuse 11 (C0585) provides a
constant battery feed to the drivers door module (C2017) on an RP wire. Fuse 24 (C0583)
provides a constant battery feed to the passenger door module (C2016) on an RW wire. The
drivers (C2017) and passenger (C2016) door modules are both earthed on N wires.
Fuse 53 (C0583) provides a constant battery feed to the ignition switch (C0099 on Td6
vehicles, C0028 on V8 vehicles) on an R wire. When the ignition switch is turned to the
'auxiliary' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8
vehicles) to fuse 41 of the passenger compartment fuse box (C0585) on a PB wire. Fuse 41
(C0586) provides an auxiliary ignition feed to the Body Control Unit (BCU) (C0660) on a PW
wire. The BCU (C0662) is earthed on an N wire.
