My 03 L322 td6 was at a shop for few days to replace one of the ABS sensors. My mechanic told me he could not connect with his diagnostic tool. It worked for me with Launch X431 before. When I got it home I tried again to connect, but most of the modules do not work anymore. I can still connect to the engine and gearbox module, but everything else like ABS, Air Suspension, etc is down. Battery is also close to 13v so this should be fine. I tried disconnecting it to reset the systems but it's all the same. I also took out the fuses for the diagnostics, but to no avail.

Any ideas how to proceed and why I am locked out of these diagnostic modules?
