Hello and thanks for using

There can be a few different things that can cause your issue. First we should check the battery as low voltage can cause this. Lets try and boost the battery to see if it will start. The battery is in the trunk but on the 2007 XK there is a positive cable connection in the driver rear of the trunk behind the vent cover. Remove the cover and look down and you should see a thick black cable. Hook up the red positive lead of your jumper to the connection under the rubber boot and the black ground cable to the exhaust. See if it needs to be boosted. Let me know.

I boosted it and there issue is still present

Press the start button with your foot off the brake and you should see a warning to press brake when starting. Depress the brake and see if the warning goes out. If not then we may have a fault with the ABS or brake switch

I have tried that already and there is no change
Expert:  Richard replied 2 years ago.

OK since all those other warnings are on looks like there may be an issue with the ABS module which may need to either be reset/reprogrammed or replaced and programmed. We can try disconnecting the negative battery terminal cable for about 10 minutes to see if it will reset.

I had done that too. If its any help I pulled the two error codes off the car u0415, and p0504
Expert:  Richard replied 2 years ago.

OK that is what I suspected. Looks like the brake switch may be faulty. We can go under the driver side dash and look up at the switch to make sure it is properly connected but looks like it may need to be replaced.
