With Jaguar PDU Scan Tool

CAUTION:
- Be sure to read Preliminary Information BEFORE attempting code diagnosis.

- It is most important to understand that franchised dealers with Portable Diagnostic Unit (PDU) have the ability to retrieve ALL stated codes. Non franchised dealers, using generic scan tools however, may NOT see codes which do not relate to an OBD II failure.

- Fault code access and system health may be effected by using Jaguar Diagnostic Equipment (PDU) or a generic scan tool. With regard to OBD II associated activities, these diagnostic aids may ONLY be used via the J1962 connector (Data Link Connector).





THE JAGUAR PORTABLE DIAGNOSTIC UNIT (PDU)
The franchised Jaguar Dealer is equipped with the PDU which is a comprehensive electrical diagnosis system specific to Jaguar vehicles. PDU can interrogate not only the engine management system, but ALL control modules on the vehicle which are similarly connected to the communications bus, it can then decode and display any diagnostic trouble codes including enhanced diagnostic information.

The PDU performs a number of specific functions, including:
1. DataLogger
2. Engine Set-up
3. Diagnostic Trouble Codes
4. Control Module Programming
5. Digital Multimeter

PDU FUNCTIONS

DataLogger
DataLogger is designed to identify intermittent faults in the vehicle electronics and can capture information from up to three sources simultaneously, i.e. Serial Communications, Vehicle Interfacing and Measurement Probes.

Diagnostic Trouble Code
This function allows the PDU to monitor selected codes and decode and display any codes or enhanced codes logged by the control modules, together with a count of occurrences. The fault codes recorded on the control modules and the PDU screen can be cleared using this function.

Engine Set-up
Engine Set-up allows adjustable engine parameters to be set to the correct criteria.

Control Module Programming
Control Module Programming is used as a setting / calibration process for the security system.

Digital Multimeter (DMM)
A Digital Multimeter enables measurement of voltage, current, resistance, frequency, pulse width, pulse period and duty cycle.
