2010 JAGUAR XFR sensor

The warning indications to the driver are common on all vehicles fitted with TPMS. The driver is alerted to system warnings by
a low tire pressure warning indicator in the instrument cluster and an applicable text message in the message centre.

The TPMS module passes system status information to the instrument cluster on the medium speed CAN bus. The instrument
cluster converts this data into illumination of the warning indicator and the display of an appropriate message.
When the ignition is switched on, the warning indicator is illuminated for 3 seconds for a bulb check.


NOTE: If the vehicle is not fitted with the TPMS, the warning indicator will not illuminate.

The instrument cluster checks, within the 3 second bulb check period, for a CAN bus message from the TPMS. During this time
the TPMS performs internal tests and CAN bus initialization. The warning indicator will be extinguished if the TPMS module
does not issue a fault message or tire pressure warning message.

If a TPMS fault warning message is detected by the instrument cluster at ignition on, the warning indicator will flash for 72
seconds after the 3 second bulb check period and then remain permanently illuminated.

If a tire pressure warning message is detected by the instrument cluster at ignition on, the warning indicator will extinguish
briefly after the 3 second bulb check period, before re-illuminating to indicate a tire pressure warning.
The following table shows the warning indicator functionality for given events:

Event Instrument Cluster Indications Low pressure warning limit reached in one wheel

Principle of Operation Published: 11-May-2011

For a detailed description of the wheels and tires, refer to the relevant Description and Operation section in the workshop
manual. REFER to: (204-04 Wheels and Tires)

Wheels and Tires (Description and Operation), Wheels and Tires (Description and Operation), Wheels and Tires (Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

1. Verify the customer complaint. As much information as possible should be gathered from the driver to assist in
diagnosing the cause(s). Confirm which of the following two warning types (A or B) exist for the Tire Pressure
Monitoring System when the ignition status is switched from 'OFF' to 'ON'
(A) Check Tire Pressure Warnings. A low tire pressure warning will continuously illuminate the low tire
pressure warning lamp. This warning may be accompanied by a text message such as CHECK TIRE PRESSURE
(refer to owner literature). The manufacturer approved diagnostic system does NOT need to be used. Diagnostic
Trouble Codes (DTCs) are not generated with this type of warning. To extinguish this warning it is essential that,
with the ignition 'ON', all vehicle tires (including the spare) are to be set to the correct pressure as stated in the
vehicle handbook or as indicated on the placard label in the passenger/driver door aperture. It is not necessary
to drive the vehicle to clear 'check tire pressure' warnings - just changing the tire pressure causes the tire
low pressure sensor to transmit new data.
NOTES:

The tire pressures should be set by:
Using a calibrated tire pressure gauge
With 'cold' tires (vehicle parked in the ambient temperature for at least one hour, not in a garage with an
artificial ambient temperature)

If the tire pressure warning does not clear within two minutes, it is likely that the gauge is not correctly
calibrated or the tires are 'warm'. Carry out the following steps until the warning has cleared:

Increase the tire pressures by 3psi
Wait a further two minutes
When the tires are at ambient temperature and a calibrated gauge is available, reset the tire pressures
to the correct pressure.

Tire pressure adjustments are part of routine owner maintenance. Tire pressure adjustments that are
required due to a lack of owner maintenance are not to be claimed under vehicle warranty.

(B) System Fault Warnings. When a system fault is detected, the low tire pressure warning lamp will flash for
approximately 75 seconds prior to being continuously illuminated. Visually inspect for obvious signs of damage
and system integrity. Check for the presence of tire low pressure sensors on all four wheels (note: a tire low
pressure sensor has a metal valve stem rather than a rubber one).
2. Check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

NOTE: If the tester fails to communicate with the Tire Pressure Monitoring System module, the following actions are
recommended:

Remove the Tire Pressure Monitoring System power supply fuse, inspect and re-install (if intact). Test to see if
communications have been re-established.

Remove the Tire Pressure Monitoring System ignition fuse (if applicable), inspect and re-install (if intact). Test to see if
communications have been re-established.
With ignition status set to 'ON', refer to the electrical circuit diagrams and check Tire Pressure Monitoring System
module for power, ignition and ground supplies .
Carry out CAN network integrity test using the manufacturer approved diagnostic system.

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00

NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. If this is the case, match the five
digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra
information read by the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places,
and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
