Got a 2016 Disco that has a U0001-87 Lost communication with the instrument cluster. Hard fault that will not clear. Gear shift module was recently replaced and fixed issue for about a month and now its doing the exact same thing.. Verified when the relay is jumped car starts right up. Scoped pin 6 and 14 at the DLC and waveform looks good no red flags. Any ideas where to start before I tear this thing apart unplugging modules.

 

Anyone?

The fact this has no responses solidifies my fear that I have made a big mistake.

 

anyone has some solutions? wich relay have you jumped to make it start?
