Ignition goes off when trying to start
Hi folks
Have anybody had an issue with ignition start button? When I press start button without brake (dash lights go on) and then press the brake and press start button again engine will not crank and all the dash lights go off. And when ignition is off I press the brake and then start button all it does it turns ignition on for about 2 secs and then ignition goes back off again. I've managed to start the car by shorting starter motor relay and this is the only way to start the car. Start button replaced, did not help. Any ideas? Thanks

BCM: Invalid signal from ABS Module and Lost communication with Parking Brake Module. Would any of these two not allow engine to start? No faults in ECU or TCM. I've also checked brake pedal switch works fine.

yes mate, it was abs pump that does not allow to start if break fluid has not reached correct pressure. I was doing it after lifting the body and all breakes were still disconnected. Ive connected all break pipes bled them up and car started without any issues. Hope this helps in your case

Im getting the same issue with my 2017 disco 5. I had replaced my telematics backup battery and after that the disco will do exactly the behavior describe by the OP. I not sure but i physically unplugged the telematics module from the car to replace the backup battery and now im guessing some configuration got messed up. I have unplugged the main battery and same thing. I have also bought a brand new battery and still getting the same thing. Checked all the fused in the 3 fuse boxes and no issues found. Not sure what to try anymore. Im guessing that the telematics module disconnect and reconnect needs the dealer to reset the ****ing car to start up again? I tried pressing the break as hard as i could but no luck and i did not mess around with the breaks.
Any ideas? Did i fry something?

Hi mate, did you manage to figure out a fix for this by any chance? I have a Range Rover sport L494 and facing the same issue, I changed the Telematics battery and since then it’s not starting?
Any help would be greatly appreciated!
