Not getting any P codes for my 2004 XJR. Am I doing something wrong or does this dang thing just not read them? Thanks, SS

 

My 04 has to be identified.
The year, model, motor, trans, has to be entered.
Where the 07 self reads to identify itself

 

Thanks Wingrider,

While my reader (Icarsoft LR V.30) doesn't identify VIN, it does allow me to enter the car in a series of drop-downs. So, assuming it is identifying the car, why do I not get "p" codes?

 

Steve, I saw somewhere that it will not read the 04s. I thought it read mine one time, but it won't now. Gives an error message along the lines of "slow communication" then won't read any codes. Will cycle some modules. I started to throw it in the trash until I read that on the 04s.
So, I tried it on my 09 and it will read the codes. Have to select Jaguar though.
Their customer service is non-existent and the upgrade download won't work either. If I could find something else that worked with the 04, I'd buy it. And it's getting difficult to find parts for the 04. I'm wondering whether or not I should pass it on.

 

Thanks so very much. Based on the documentation, in some cases poorly translated, this appears to be another shody Chinese company. I wish that I hadn't purchased.
