My X300 just died twice upon starting before finally starting and running as usual. I'm thinking it would be cool to look at the codes, such as they may be, to try and understand what happened.

Does anyone have a recommendation for an X300 friendly OBD2 code reader?

Thanks in advance,
Rhett

 

I'm using a Wifi wireless ELM327 with the Dash Command app on my IPad and IPhone. Works great!

 

Similar to Knealy2 - except a Bluetooth ELM 327 adapter and TorquePro for Android. If you fancy reading chassis codes; you'll need to up the ante a bit - Autoenginuity with Jaguar module - several hundred dollars vs. maybe $30 or so for an adapter and app, assuming you already have the phone.

 

My AE does not read codes on my '95. From what I have read, it may work with the '97 X300 and it works with my XK8. But the Ultragauge at least reads and erases P codes, temperature,TPI and STFT. I have it mounted on a bracket and leave it plugged in.

 

Similar to some of the others, I use an ELM 327 wifi adaptor and OBD Fusion for my iPad and iPhone. I believe it is quite similar to the Torque app for Android. It allows me to read codes and reset the CEL but i use it the most to read live data to gauge engine performance and help troubleshoot.

This is more useful on the 95MY as it seems to almost never throw a trouble code!!

The displays are configurable and allow you to graph data as well. Here are a couple of examples

 

I have both USB and wifi ELM interface. Use laptop, iOS and Android. Got lot's of different apps, but they seem to do about the same.

My personal favorite is OBD Fusion on wifi/iOS, the same as AllanG uses. TouchScan is the name for the same software on pc and Android, but the name was taken by the time the app was ready for iOS, hence the "OBD Fusion" name I used this app to troubleshoot a very complicated TPS turning bad and it is also great for adjusting the throttle cable, so you can see when it is too tight and the TPS starts moving.

 

Which if any of these supports Jaguar X300 specific PIDs such as cylinder misfires?

I'd hate to pick up another (I have an Actron 9145) that only shows the basics and none/few Jag specific.

.

 

Sorry to resurrect an old thread. Invested in the OBD fusion iOS app. Only getting battery voltage and no codes on my 1995 X300. Anyone have any suggestions??

 

As others have mentioned I similarly use a Bluetooth ELM 327 adapter with Torque Pro for Android, I picked up the Bluetooth ELM off ebay from China for next to nothing, Thinking if it didn't work no harm done. It has worked a treat and has saved me big $$$ a couple of times

 

Thanks for your reply. I did the same but aren’t getting much of use. The adapter seems to connect but OBD fusion doesn’t seem to give me much. Take a look at the screenshots below.

 

Can you confirm you have the AJ16 engine?

 

yes XJ6 X300 4.0 Sovereign 1995.

 

That's not a surprise, but probably a disappointment. I always thought that both 1995 and 1996 model year engines would be equally OBD2 compliant, but it seems that Jaguar really didn't have it all finished. I think you have a kind-of compliant OBD2 car. You can certainly try another program, but I doubt you'll have a better experience.

I use OBD2 Fusion for my 1996 AJ16 car, and I get more that what you're getting. I am also using the ELM27 connector. The best I could recommend is to try someone else's ELM27, if you know anyone that has it, or try someone else's OBD2 reader before spending any more money.

 

I had both very early X300 and very late X300, and now have middle 1996 model and all three worked well with my simple D900 OBD scanner.

I'm pretty sure I've used ELM on first two cars too but always preferred D900 for any diagnostics anyway.




They are cheap and readily available.

 

Okay thanks. That’s disappointing. I will check out the D900 OBD scanner. Does it do data stream? Or just read and clear codes?
