temperature sensor JAGUAR X308 1998 2.G Owners Manual

System Self-test
Control Panel Fault Code Listing • NOTE: Reference fault code #23*: In ambient temperatures below 0° C, this code may be logged because the low
ambient causes a tempor ary low gas pressure.
• NOTE: Where the ambient temperature rises above 40° C, with the engine close to overheating, electrical feed to the
compressor clutch may be cut and code #23 registered.

r to PDU User Guide
The c
o
mplexity of the electronics involved with the Instrument Cluster and the two multiplexed communication networks
which are connected to it, preclude the use of workshop genera l electrical test equipment. Therefore, reference should be
made to the PDU User Guide for detailed instructions on testing the Instrument Clus ter and associated circuits.
The PDU systematically test s and analyses all functions of the Instrument Clus ter, the various systems controlled by it and
individual sensors which are attached to each separate system.
Where a fault involving a remote sensor e. g. water temperature sensor, is indicated, before replacing the component, some
basic diagnostic methods may be necessary to confirm that connections are good and that wiring is not damaged.
Diagnostics using the PDU is via the CAN network, accessed at the diagnostic connector on the car.
Replaceable Parts
The only replaceable part s
are, General Illumination Bulbs, Direction Indicator Warning Bu
lbs and Main Beam Warning Bulb,
which are all of the conventional filament type. Other warning lamps are LEDs and are not replaceable.
