Check component 225 on the vehicle:
–Check for + 12 V battery feed on connection BCP4 (Laguna), BP32 (Mégane and Scénic) or BP10 (commercial
vehicle), + 12 V after ignition feed on connection AP10 (Laguna), AP43 (Mégane and Scénic) or AP26
(commercial vehicle) and an earth on connections MA, MB and NAP (Laguna), NC and MK (LHD commercial
vehicle), NJ and MJ (RHD commercial vehicle), MAM and NAM (Scénic), MAM and NAM (RHD Mégane), MAN
and NAM (LHD Mégane), of component 225.
