Hi, i cant seem to get a straight answer on this. I have a late 95 XJS AJ16 4ltr and wanted to get icarsoft LR V2.0 scanner. Ive had a seller tell me the car is not compliant but online and in this forum it states my model Jag is OBD11 compliant??
is there a better option that will for sure be compliant with my car or is the icarsoft fine?

 

Hi Phil, I have a 1995 XJS 4 litre AJ16 with the OBDII port. I also have an XF Sportbrake for which I purchased the iCarsoft LR 3.0 and can say the iCarsoft unit does not work with my 1995 XJS. I had more success with a simple Bluetooth ELM327 compatible OBDII reader with the Torque app and this gave some live data and fuel trims but didn't get into all the data that should be available. I then sourced an Autotop D900 scanner circa 2008 from eBay and that has been better but still not providing a complete read of codes. I think there are two problems;
1) In 1995 the OBDII protocol was still in its infancy - it didn't become mainstream until 1996 so in 1995 the Jaguar implementation was perhaps still somewhat proprietary
2) I think the communications protocol is SAE J1850 of which there were Ford versions (PWM Pulse Width Modulation, 41.6 kbps) and GM versions (VPW Variable Pulse Width, 10.4 kbps).Given Ford owned Jaguar at the time the Ford implementation would seem the way to go. Some OBDII readers claim to support this protocol but from internet searches I'm not sure they are necessarily complete implementations of the protocol.

There was a Jaguar code reader for main dealers but this was a large workshop unit and I think most have been scrapped.

Hope this helps, if you find anything that works well for you please post it on the forum as I know many other owners have looked into this.

 

Thanks for the response. Did some more research and innova 5210 seems to be a good one, waiting to speak to them 1st

 

Phil,

As CS_XJS has mentioned, OBDII was in its infancy when Jaguar introduced it on the AJ16 XJS in April 1994. There was a revision to a more comprehensive software package for the 1996 MY which was in mid 1995 at VIN 222632. So it's quite likely if you've got a late 1995 car that it has got the revised software. Generally, the OBDII protocol in AJ16s is ok, but I believe that one of the metrics, I think the LTFT has an error where the figure is displayed 10x higher than the reality due to a software glitch? Don't quote me, but I think that's the problem area.

As mentioned, some of the very basic ELM327 plugins and cheap or free software such as Torque Pro work fine for basic engine codes and real-time live figures even on the first 1994-built cars.

Good luck

Paul

 

Cheers Paul, yeah im Nov 95 so should be ok on the software. Might give the cheap software a go but think the innova 5210 will do the trick on mine

 

So I just ordered the LR V4.0 after being back and forth with a few alternatives to the suppliers. Icarsoft claim v4.0 will do a variety of functions based on my VIN, nov 95 reg so i believe the later the better. I was going to get the basic free one but it will work on the merc as its only 10yrs old so if anything it will work for this. Will let you know how it goes on the Jag

 

It will be interesting to learn from your experience. My car is a 1995 MY car built in September 1994 so perhaps your later 1995 car your will be more compatible. It would also be useful if you shared the chassis number of your car as I'm not sure if anybody knows when the system was upgraded. As I recall my research indicated the the OBDII system was upgraded sometime in 1995 for 1996 MY cars but I couldn't find anything definitive. It might also depend on the destination market as I believe OBDII was becoming mandatory in the USA.

 

Sure they number is SAJJNAED3EJ223484, RHD registered in England originally

 

Phil,'

FYI. As I mentioned earlier in the thread, 96 MY is VIN 222632.

Cheers

Paul

 

Paul, apologies, my brain hadn't remembered your reply when thinking about the OBII upgrade date.
Chris

 

No offence taken at all Chris!
