Is this something I should consider buying. Im not a mechanic but I have just become the owner of a 2002 S-Type Jag, V6 Sport Auto Petrol?

 

I got this from google with
OBD

On-board diagnostics - Wikipedia, the free encyclopedia

It's worth trying google...

 

If you've got a smartphone, buy an ELM327 bluetooth mini from ebay for less than £6 and install the free Torque app on your phone.

 

If you have an iPhone, do not buy the Bluetooth version of the ELM327 tool. Instead, buy the WiFi version as the Bluetooth is incompatible with most iPhones. And, unfortunately, there is no iPhone version of Torque that I know of, so you'll have to find a different OBDII app if you're using iPhone. There are several available in the app store.

 

Thanks fellas, I have a ~HTC at the mo

 

Get the bluetooth as suggested by Corv. Install Torque app on your phone.

 

Be aware some elm clones won't work on the early cars, the ones without the electronic Park brake.

Some do some don't it's pot luck.

 

That looks like a really good idea. I might go for one. My car has electronic park break. Thing is will I be able to read and decifer the codes?

 

PS: Just back from mechanic. Jag mechanic said alternator is giving power problems. New alternator and still 'limp mode' :-(

 

Yep, you will be able to read engine codes, and either Google the, search and ask on here or check jtis or alldata.
