Illumination Relay
Vehicles fitted with an instrument dimmer switch are also fitted with an illumination relay. 
Fuse 16 of the passenger compartment fuse box (C0589) provides a constant battery feed 
to the illumination relay (C1976) on a pair of P wires. The earth path for the relay coil (C1976) 
is controlled by the CCU (C0592) on a BR wire.
The CCU (C0593) provides an earth path for the relay coil when it receives a key in signal 
from the transponder...

Fuse 16 (C0580) also provides a constant battery feed to the rear interior lamp (C0356) on 
a P wire. When the interior lamp switch is in the normal position, the earth path for the lamp 
(C0356) is controlled by the CCU (C0593) via the passenger compartment fuse box (C0582) 
on a PW wire. The CCU will illuminate the interior lamp if it senses any of the doors are open 
(see Central Control Unit – CCU).
When the switch is pressed, current flows across the...

INSTRUMENTS
DESCRIPTION
General
The instrument pack is a totally electronic controlled device receiving electrical signals from 
sender units, and CAN messages from the Engine Control Module (ECM), the ABS ECU, 
the Electronic Automatic Transmission Electronic Control Unit (EAT ECU) and the cruise 
control interface unit (Td4 vehicles only). The instrument pack transposes these via a 
microprocessor into analogue gauge read out and warning lamp...

DESCRIPTION AND OPERATION
FREELANDER 04MY 4.129
Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the 
ignition switch is turned to the ignition position, current flows across the switch (C0028) to 
fuse 18 of the passenger compartment fuse box (C0588) on a G wire. Fuse 18 (C0589) 
provides an ignition feed to the instrument pack (C0233) on a G wire.
The warning lamps contained within the instrument operate as follows:
zThe LH direction indicator warning lamp (C0233)...

zThe handbrake/low brake fluid warning lamp receives a constant battery feed from fuse 
16 of the passenger compartment fuse box (C0589) on a P wire. Illumination of the 
lamp is controlled by the handbrake switch (C0091) on a BW wire. When the 
handbrake is applied, the switch contacts close and an earth path is created, 
illuminating the lamp. Illumination of the lamp is also controlled by the ABS ECU 
(C0501) via the CAN BUS on YN (Low) and YB (High)...
