OBD II scanner

![Default](/forum/images/icons/icon1.gif)
So with the wife returning home with the 2006 XK8 on a flatbed truck, time for me to get a better scan tool. I think it is the fuel pump but since there is no test port on the fuel rail, need to be able to access the short and long term fuel trims and my old scanner just reads codes.
Is Dash Command the one to get for the 4.2L engine or is there something else?
Been doing a search but have not found a good answer to which scanner to get.
Thanks in advance.

There is a fuel pressure sensor, and it can be read over OBDII. Should read 55psi.
For the hardware device, you cannot go wrong with a cheap ELM327 device. I believe the newer models have both Bluetooth for Android and Wifi for Apple products. Dash Command is one of the software apps that can read from the ELM devices, but there are others. To be clear, these generic apps will only read standard OBD codes, but nothing specific to Jaguar (the ELM device can read everything, but the software has no coded knowledge of Jaguar/land Rover).
Other option is to bite the proverbial bullet, and get a JLR reader. Some, like the Foxwell device can even accept software for more than one type of car (for a fee of course), so one device can be used around the garage more. Might be able to justify the expense that way a bit more.
Best of luck, keep us posted.

Hi,
i recently had a DSC fault message with amber warning lamp on my XK8 4.2 MY 2003. Tried to scan it with SCANMASTER/ELM327, result was no error code detected.
So I ordered the original IDS/SDD software (V130) and a Clone Mongoose interface from British Diagnostics, took me just 100 bucks.
The DTC read out was C1288 (Pressure sensor main / primary input circuit failure) and led me to a cable hard to access and deep under the master cylinder. It was pinched and therefore short to ground.
I´m convinced that i would have much more obstacles on the way with any other obd scanner.
If you have an alternative avoid to order at British Diagnostic. It means long delivery time (almost 4 weeks) and absolutely no communication.

The 4.2 engine has a schraeder valve (looks like tire air valve) on the front left hand side of the fuel rail. Turn the ignition to ON position II but not start, turn it off and then press down on the valve. Have a rag over it because pressure can be as high as 4.5 bar. Do you get a heavy pressurized stream, just a low pressure bit of fuel or no fuel at all. No fuel would indicate a possible electrical problem in the fuel circuit or a failed pump. A small amount of fuel could be a possible fuel pressure regulator failure. A heavy stream and pressure would indicate all's well in the fuel circuit.
My choice for the scanner was the icarsoft LRII for Jaguar/Land Rover specific and it will also work with other OBDII cars. It comes with the necessay software to query Jaguar modules.

I used my old scanner and pulled the codes, P2135 TPS error along with two pending codes of P1111 and P1797.
I loosen the two clamps on the intake pipe so I could get a better look at the throttle body and upon removing the intake pipe, saw the problem. The intake pipe was crumbing along the flex portion of it, which was allowing unmetered air into engine.
I wrapped the intake pipe with good 'ole duct tape, re-installed it, cleared the codes, went for a 25 mile drive and no problems.
I have ordered a replacement intake pipe for $135.
The P2135 code seems odd to me, thought a MAF error code would have been set instead.
I still need to get a scanner that will pull live data, so looking at the ELM327 devices as well as the other two stated above. Have other vehicles that I need to have capability to pull live data from as well as the XK8.
Thanks for the scanner comments....that is what I am needing.
Oh and my '06 4.2L engine does not have a schraeder valve on the fuel rail. It does have the pressure sensor connected at the right side rear. No idea what year this replaced the schraeder valve.

I've never seen a fuel pressure reading going through the Torque app.
Thanks for the tip about Dash Command. I've been a bit frustrated with Torque but never got around to looking for an alternative.

The 4.2 engine was updated to a return-less system, so fuel pressure reading is an integral part of the system. The 4.0 has the more conventional system with a regulator and a return hose. Only the 4.2 offers fuel pressure over OBDII.

I also found a list of specific Jaguar Codes on the iCarsoft site. It listed some 629 codes, as compared to Sam's list of 165. While some were the same, most were different. Is there a current, complete and accurate list of Jaguar codes??

you might want to check out the prices on Amazon.On Amazon the iCarsoft LR V2.0 is only $145 now. I bought the icarsoft v 1.0 @ $100 because it looked to me like the v 2.0 had features that were only needed or usable on cars newer than my 2002 XKR.

Well, having read all I can find, it seems that the main concerns about iCarsoft is the non existent tech support and whimpy manual. Foxwell, on the other hand, have a better manual and tech support, but a tiny screen by today's standard.
Then I found AutoEnginuity. Sure is pricey at $500:- if you also want the Jaguar specific software. But, there is something appealing about using a Laptop PC.
So, the question is - anybody out there using the AutoEnginuity??? What does it do that the Foxwell or iCarsoft does not???

Hi Nalle
Did you ever get your question answered "anybody out there using the AutoEnginuity??? What does it do that the Foxwell or iCarsoft does not???"
I have just connected and been playing with a cheap ELM327 to iPhone app Car Scanner OBDII but while it gives Interesting dynamic data, and does a DTC check there is no Jaguar code reading of course.
so while I'm catching up on mechanical maintenance of a newly acquired '97 XK8 coupe and have no major faults showing on dash its only a matter of time.....!??
So what's the next step?
Would appreciate your thoughts or those of others - recommendations appreciated!!
Dave
