My 2004 XJ8 recently started messaging "park brake fault' and now battery is being drained every 24 hours. Have checked the fuses, All seem OK. Any ideas?

Something, probably NOT the park brake, is causing a drain - go hunting. I like to measure the volts across each fuse (see existing posts / youtube).

The brake message usually just reflects the flattened battery.
