As of MY2003 all electronics and controls were moved to hydraulic unit behind left headlight. Only thing left over in fuse box is 40A fuse for the pump.Hello all, I am trying to debug the subject issue here, BAS/ETS/ABS.. lights. The three lights under this discussion. Step 1 as suggested was to jump relay K25 to see if the motor kicks in. However, i opened up my fuse box and K25 is empty, no relay there and it is also left blank on the list under the fusebox cover. Mine is a 2005 W163. I also checked inside fusebox location but not there eithet. Does anyone know where it was moved or if this is a design change for this year? Thank you!
