2006 5.7 Hemi -ABS speed sensor communication error. Brake , ABS, and Check Engine lights on Dash. Speedometer gauge not operating. Code U1120. REPLACED front ABS Speed Sensor unnecessarily. FOUND FUSE SLOT 30 marked "Spare" was actually protecting the ABS curcuit. Replaced blown fuse in "spare" slot; problem solved
