Posted October 30, 201014 yr A 2004 when you first crank up the ABS light comes on and the alarm will ding, then it will go out after maybe 20 seconds. Anybody have any ideas what it may be? Thanks for any help.

But becareful and disconnect the batteries for at least 15 minutes before messing with any connector. This will prevent a accidential discharge of the ABS system.
