Symptom Driven Diagnostics (SDD)

Jaguar Land Rover Diagnostics

To help us correctly diagnose faults on your vehicle and carry out certain service functions as well as key and module programming we use the dedicated SDD (symptom driven diagnostics) platform as recommended by JLR our equipment is exactly the same as the main dealer , we pay a yearly subscription to JLR and receive updates from JLR over the internet so our software is always at the correct level.



Every 2 years we have to reapply to JLR for security accreditation which allows us to program keys and security related modules.

For early Jaguar vehicles 1995-2005 we use the old Jaguar WDS diagnostics system (pictured above) and the Autologic diagnostic system (top picture) which is also used on early Land Rover vehicles.

A Diagnostic Myth Explained

Today's modern vehicles are extremely complex as is the equipment to carry out fault finding on them, contrary to popular belief and many forums you cannot ‘Plug’ in a diagnostic tool and it will tell you what is wrong andhow to repair that vehicle.
SDD uses information that is put in to it by the technician (i.e. engine speed restricted) it will then read the fault codes on the vehicle and the Module concerned (powertrain) once this is complete it will show the codes that are relevant to the fault and show any known issues if applicable, if the fault code was related to a misfire on a petrol engine then more than likely the diagnosis would be straightforward with the outcome likely to be a spark plug or ignition coil fault and would not be time consuming to repair , on the other hand if the fault codes where related to a turbocharger fault there are lots of other factors that could cause the code to be stored , it is now down to the technician to carry out a more detailed investigation into the area concerned before jumping into an incorrect and expensive repair, even with machines like SDD and other diagnostic aids fault finding on today's high tech vehicles can be very time consuming.
