A5.6 SYSTEM DIAGNOSTIC METHODS
The following information details diagnostic proceduresfor system fault identification using a Portable Diagnostic Unit
(PDU).
PDU is designed and supplied by Jaguar Cars Ltd. to interrogate the electroniccontrol circuitry of the various vehicle
systems, diagnose fault conditions and indicate to the operator recorded faults and possible remedies. On initiation
of diagnostic procedures PDU will display the model variant and control module type,
a list of enabled functions can
also be accessed. Ensure that this information is correct for the vehicle under test, ie that the correct module is fitted
and
all appropriate options are enabled.
Detailed information on testing using PDU is detailed in the support documentation supplied with the unit.
