Default XC70 Rear Brake Light Relay Diagram

Hi everybody,
does anyone have a diagram of the rear relay board for the XC70? I have both back brake lights not working while the centre high mounted LED one does. That with the instrument console reporting a brake light failurediscountsa faulty switchat the pedal. Fuse and light bulbs check out OK (I changed the bulbs just in case) so I can only imagine that it must be the relays...


PS Does anyone know what the 'shunts' do?

I have the opposite problem.
My upper LED brake light does not work, regular rear braking bulbs do work. However I have a a bulb failure dash light coming on with my Left turn signal only, and although signal works (front and rear) it does indicate much quicker than the right, like 1 bulb is out.
