Quote from: copycats on January 16, 2011, 10:19:13Personaly I think it needs a ECU reset...There's a device behind the dash called the BCM (Body Control Module) that controls the lights (and other things). Not sure how that would get reset, other than by the dealership.Might be tempted to disconnect the battery for half an hour to see if that helps. After reconnecting it of course
Does a longer disconnection time make a difference do you think?
try half an hour, to an hour.
Right here is my 2 pennyworth, more like a quid As it is both rear side and not the high one then I would expect it to do with the wire contact.If you have a tester remove one of the bulbs and see if current is present when the brake pedal is pressed. If not try the other.If current present then it may be a problem with the holder or even the bulb contact points.Also, try and trace the wire from 1 unit to other and see whether it has been knocked and not making contact.Did this happen after you used the boot and may be knocked some componets?PS as you use it for taxi service do you get spot checked by the Council? If so, get it sorted ASAP before you are pulled off the road.Also, is this a mandatory fine/points by our boys in blue for not having brake lights?
Do your reversing lights work? They share a common ground with the brake lights.
Not suprised it's a good one. I dint want you to feel insulted at this next question! But are you really sure you replaced the brake light bulbs - they possibly aren't where you think they are in the cluster. You know they are double element 21/5W? (If my memory servers correctly).My recollection is that it would be really easy to replace the rear fog light bulbs (single element 21W) thinking you had done the brake lights.....
Do you know how long this has been like this?Just try to eliminate actions which may have contributed to the non functioning!!!From day 1!
If you turn the headlights on do the 5w fillaments in the brake bulbs come on?
Ok, so it's not going to be a ground/earthing fault.I think everything would point to a wiring fault in proximity to where the wires run through the grommet in the top of the tailgate. But as Hyundai don't seem to want me reading their wiring diagrams that's as good a guess as I can have
Dealers are a bit luck-of-the draw, but as far as warranty work is concerned that will no doubt treat you like anyone else (heh). Hyundai pay them for the work, so it's all revenue for the dealer.
