[QUOTE="mcatrophy, post: 1182269, member: 3187"] Real question is, do you still have an incandescent bulb as a brake light? If not, you are very likely to get the ABS error unless you do something about it. The ABS monitors the voltage on the brake light circuit. Without the filament pulling that voltage to close to zero, the ABS system may well "see" too high a voltage (it probably bleeds some current into the circuit to check its own connectivity). Why your '06 didn't show an error and your '09 does, I can't speculate (well, I could, but it would be a waste of time). The cure would be a changeover relay as many have used to kid an after-market cruise control that all is OK after they have fitted LED brake lights or whatever, though that might not be as easy to implement.
