Evaporative Emissions System
The function and operation of the on-board
refueling vapor recovery (ORVR) evaporative
emissions system are similar to the system fitted
to the XJ and XK Series vehicles in NAS markets
but use different components. For the S-TYPE the
system is fitted as standard for all markets.
Fuel Tank Components
To meet ORVR evaporative emission
requirements, the tank and associated
components are designed to minimise vapour
losses. During re-fuelling, the narrowed fuel filler
tube below the nozzle region provides a liquidseal against the escape of vapour and a check
valve in the tank inlet pipe opens to incoming fuel
only to prevent splashback. As the tank fills,
vapour escapes through the open float level vent
valve, at the top of the tank, and passes through
the adsorption canisters to atmosphere. When the
rising fuel level closes the float valve, the resulting
back pressure causes refuelling cut-off. While the
float valve is closed, any further rise in vapour
pressure is relieved by the grade vent valve which
connects to the canisters via the outlet of the float
valve. At less than full tank level, the float valve is
always open, providing an unrestricted vapour
outlet to the canisters.
If the tank is over filled (eg a fault in the delivery
system) an integral pressure relief valve in the float
valve assembly opens to provide a direct vent to
atmosphere.
The float level vent valve/pressure relief valve
assembly and the grade valve are welded to the
tank top and are non-serviceable. Note that both
valve assemblies incorporate roll-over protection.
The fuel filler cap uses a 1/8 turn action and is
tethered to the body. The filler cap assembly
incorporates both pressure relief and vacuum
relief valves (the latter is a new feature to Jaguar).

Carbon Canister Assembly
Three series connected carbon canisters are used
for vapour storage and are mounted on a plastic
bracket fixed to the underbody above the rear
axle. For Federal markets only, where there is a
requirement for leak test diagnostics, a canister
vent valve (CC valve) is also mounted on the
canister bracket and a fuel tank pressure (FTP)
sensor is fitted to the vapour pipe.
Evaporative Purge Valve
The EVAP valve is mounted on the rear lefthand
side of the engine bay. The valve is different to
XK/XJ Series types but is controlled in a similar
way by a PWM signal and manifold vacuum.

76Air Conditioning Control Module (A/CCM)
The A/CCM is connected to the SCP
communication network. The A/CCM controls
automatic climate functions that maintain the
vehicle at a constant temperature setting.
Instrument Pack
The instrument pack is connected to the SCP
communication network. The instrument pack
displays information received on the SCP
including speedometer, odometer, fuel, and
message center warnings. The instrument pack
also controls the passive anti-theft system (PATS).
General Electronic Control Module (GECM)
The GECM is connected to the SCP
communication network. This module is located
behind the LH ÔAÕ post trim panel below the
fascia. The GECM controls many of the bodysystems, being directly linked to the interior
lighting, wiper and security systems. It is a support
module for other systems including exterior
lighting, locking, remote entry, mirrors
(passenger), seat/mirror/steering column memory
recall and windows.
Rear Electronic Control Module (RECM)
The RECM is connected to the SCP
communication network. This module is located in
the passenger side luggage compartment behind
the trim panel. The RECM controls the
locking/unlocking of the front passenger and rear
doors and provides power control of the fuel
pump.
Powertrain Control Module (PCM)
The PCM is connected to the SCP communication
network. For the location of this module see the S-
TYPE Powertrain Technical Guide The PCM
controls the engine performance, electronic
ignition, emission controls, speed control,
transmission and on board diagnostics.
Steering Column Lock Module (SCLM)
The SCLM is connected to the SCP communication
network. The module is an integrated unit
containing the steering column lock and lock drive
and is controlled remotely from the separate
ignition barrel.
Restraints Control Module (RCM)
The RCM is connected to the ISO 9141
communication network. The RCM controls the
deployment of the air bags based on sensor
inputs.
Vehicle Emergency Control Module (VECM)
The VECM is connected to the SCP
communication network. The module allows a
user to request emergency assistance (police,
ambulance, fire, wrecker) or directions to a
desired location at the touch of a button. Also, if
any of the vehicleÕs airbags are deployed while the
VEMS system is powered ON, the system
automatically issues a call for emergency
assistance.
Voice Activation Control Module (VACM)
The VACM is connected to the SCP
communication network. This module is located in
the driver side luggage compartment behind the
trim panel. The VACM controls and processes all

Transit Relay
The purpose of the Transit Relay is to prevent the
battery from being discharged during transit and
Dealer storage. It automatically isolates the
battery following ignition off.
The transit relay is installed on the Negative line
through a spur from the trunk lighting harness
and is located on the battery Negative post.
If the vehicle is to be handed over to a customer
within a period of 24 hours of completion of the
PDI, the Transit Relay MUST be removed.
If the vehicle is NOT to be handed over to a
customer within a period of 24 hours of
completion of the PDI, a Transit Relay Test Lead
must be fitted to allow the PDI to proceed.
Under no circumstances should any means other
than the test lead be used to bridge the Transit
Relay.
The Transit Relay Test Lead MUST be removed
after the completion of the PDI and stored for
further use. Under no circumstances should the
vehicle be transported with the Transit Relay Test
Lead fitted.
The procedure to fit the Transit Relay Test Lead
and remove the Transit Relay is given in the PDI
Manual.
