Multimedia doesn't work
Hello, I have a problem on my 2010 jaguar xf, the screen does not turn on, if I take off the battery cable and put back, the multimedia shows the jaguar logo and after 10 seconds turn off again , I already did the battery test and checked all connections, someone had the same problem before or has some advice ? Thanks

FYI this forum isn't massively busy so "bump"/"up" posts aren't really going to get you any more replies, it takes a good week for a post to fall off the front page.
With the screen, if you've checked battery and the connections (including those to the screen) then in all honesty you've done pretty much all anyone can do without a computer with a programming cable. The issue could be a module failure or sometimes just the module can need a reflash - see the attached TSB which is semi-relevant. You have a few choices here: buy a genuine Jaguar programming cable and pay for a subscription to Jaguar's SDD Diagnostics software (not cheap), buy a non-genuine cable that usually comes with software (cheaper, but the software is not exactly easy to use), or take the car to the dealer and see if they can a) tell you what's wrong with it or b) just try reflashing the module, and in all honesty is probably the cheapest option unless you can find someone near you with the cable/software or a high-end programmer like the Autels. Not the answer you wanted to hear, but this system uses a MOST Bus so not really easy to diagnose for the average DIYer. |
The serial MOST bus uses a daisy-chain topology or ring topology To the OP you would need a code reader that can access all modules on the car, the iCarSoft i930 seems popular for this. For the screen issues I've seen on the forums the common module related failures were navigation, bluetooth or audio connectivity modules. It can be any module really of which there are dozens, and some even required to be brand new replacements and coded specifically to your VIN by dealer. $$$$ |

Thank you for linking that wiki, this goes a long way to explain why these cars have so many electrical issues. Its like the the old christmas lights, one bulb goes out and the whole thing goes dark.

If you search around on the forum, someone did a good diagnostic of these issues. You get a fiber loop and bypass each module in turn and see when the screen fully boots up. When it does you have found the faulty module. Most commonly the ones under the passenger seat - Bluetooth, Sirius etc. most of those are easily replaced via eBay or similar and are not coded
Screen unit itself and some of the others are more expensive |
