Asked by for the 2008 GMC Sierra 1500
There are few possible reasons for this, so the best thing to do is have the ABS system scan tested to confirm what the actual problem is! Can't guess at it and hope to get it right!!

Exactly what Pushrod said. It has to be scanned to extract codes. Is it 4WD? The front wheel bearings can make the ABS light come on when they get excessive play. Also there are problems with the 4WD selector switch on the dash.
