SDD Symptom Driven Diagnostics

SDD is the latest development by JLR in vehicle diagnostics. Designed to be easy to use and extremely efficient in fault finding. Conventional diagnostic systems read fault codes and offer them to the end user. It is then upto the the end user to analyse the codes and find the vehicle fault from the data that has been provided.

SDD instead asks the end user the fault with the vehicle and progresses to analyse the fault codes and offers the solution to fix the vehicle on a relevance to likely ratio. A more straightforward approach for owners and mechanics.

Should you wish to intervene and only see the fault codes then this option is open to the end user but keep in mind, SDD was developed to recommend the repairs and work on a flowchart like basis.

Alongside diagnostics the service functions allows vehicle and module programming and vehicle customisation
