Jaguar OBD II System
The Jaguar X Type On-Board Diagnostics, or OBD, refers to the vehicle's self-diagnostic and reporting capability. OBD Systems were first implemented in American vehicles in the 1970's as part of the drive by vehicle manufacturers to meet EPA standards. Central to achieving this was the inclusion of electronic control systems, sensors and a centralised computerised control system. Early OBD was very much manufacturer specific with limited information generating capabilities, and indication could be just illumination of the engine fault light (MIL). Jaguar first included the system in cars using the AJ16 (SC) engine.
Current OBD II systems give the technician access to far more information on various vehicle sub-systems, and sensors. The type and amount of diagnostic information available via OBD II still varies widely between manufacturers but the standardised digital communications port has been adopted by almost all.
In the Jaguar X Type the OBD II Port is located under the dash to the right hand side of the steering wheel (RHD Cars) or below the dash to the left hand side of the steering wheel (LHD Cars).

P-Codes
P-Codes, or OBD II codes beginning with the designation P-0xxx are
Society of Automotive Engineers (SAE) defined codes. These are generic
to all vehicles and vehicle manufacturers selling into the US and Europe.
The DTCs originally developed for OBD-II systems are based on SAE
J2012 standards.
P-Codes beginning with the designation P-1xxx are manufacturer
specific codes which may be associated with a particular ECM,
component or system. In such cases there may not be an equivalent
SAE code definition.
Generic plug-in diagnostic tools can be used to read fault or
error codes, but as many Jaguar codes are manufacturer specific, all
but the most expensive code readers will require that you also have
access to a manual or other reference to find out what the codes
mean.

The icon link above will allow you to search our database for codes generated by the OBD II system and is of course only valid for Jaguar X-type and S-type vehicles.
