installed to the vehicle at the factory/dealer and
could have been substituted. Refer to the note above
the DTC index about replacing components which may
remain under manufacturer warranty.
Re-install the original or a new tire pressure monitoring system control module.
Component Tests
Wheels and Tires
For wheel and tire specification information (pressures, torques, etc).
When replacing wheels or tires, local legislation regarding health and safety must be complied with.
If the vehicle has a Tire Pressure Monitoring System installed, only Jaguar approved wheels and tires should be used. If the
wheel and tire size is changed (for example from R18 to R20) the Tire Pressure Monitoring System module should be updated
with the correct pressure information appropriate to the new wheel and tire set. Update the Tire Pressure Monitoring System
module using the Jaguar approved diagnostic system.
As a general guideline, only replace tires in pairs or as a set, and only with tires of equivalent size and specification.
Confirm the symptoms of the customer complaint.
As much information as possible should be gathered from the driver to assist in diagnosing the cause(s).
1. Before a road test, carry out a basic inspection to make sure the vehicle is safe and legal to drive.
Basic inspection
Correct tire inflation
Legal tire tread depth
