DESCRIPTION AND OPERATION
RANGE ROVER 4.23
INTERIOR MIRROR
DESCRIPTION
General
New Range Rover is fitted with an automatically dimming 'electrochromic' interior mirror. A
light sensor, incorporated into the interior mirror, dims the mirror if it detects a light source
behind the vehicle. The interior mirror also provides an output to both door mirrors, allowing
dimming of all three rear view mirrors.
OPERATION
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fuse 43 and fuse 53 of the
passenger compartment fuse box (C0632) on an R wire. Fuse 43 (C0586) provides a
constant battery feed to the interior mirror (C0698) on an RY wire.
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
'ignition' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8
vehicles) to fuse 6 of the passenger compartment fuse box (C0585) on a G wire. Fuse 6
(C0587) provides an auxiliary ignition feed to the interior mirror (C0698) on a GW wire. The
interior mirror (C0698) is earthed on an NB wire.
Automatic Dimming
When the light sensor incorporated in the interior mirror detects a light source from behind
the vehicle, it automatically dims the interior mirror. When this happens, the interior mirror
will also dim both the drivers and passenger door mirrors.
Drivers Door Mirror
The interior mirror (C0698) provides an output to the drivers door mirror (C2292) on WR then
P and WU then B wires. When the drivers door mirror receives these feeds, it automatically
dims. When the light source is removed from behind the vehicle, the feeds are removed and
the drivers door mirror returns to normal brightness.
Passenger Door Mirror
The interior mirror (C0698) provides an output to the passenger door mirror (C2292) on WG
then P and WY then B wires. When the passenger door mirror receives these feeds, it
automatically dims. When the light source is removed from behind the vehicle, the feeds are
removed and the passenger door mirror returns to normal brightness.
NOTE: The drivers and passenger door mirrors have the same connector number as they
utilise the same harness.
