    Recently had my battery disconnected to recharge it as the car had been parked up with a falled sbc pump. After reconnecting the battery I'm now getting a message on the dash saying "active lighting system display faulty".
    Car is a 2005 cls55 amg with the active headlights option. Is their a reset sequence I need to do after reconnecting the battery? I have access to star diagnostic but unsure what I'm actually looking for.

    My active headlights needed resetting after driving into a deep pothole and failing its MOT.

    It was reset on STAR at a local indy but not sure exactly what was done.
    I believe the aim was "zeroed" then recalibrated.
    Hopefully an indy here can comment on the procedure.
