Problem when driving the abs light comes on .the trans shifts funny and the speedometer is very erratic ..replaced the speed sensor and still does this. jacked the rear off the ground and ran the van .light doesn't come on so I back probed the frt. sensors left frt. voltage was 4.21 right frt 7.60 so I replaced the left frt. wheel sensor and the light still comes on .....What gives here...Thanks

 

Can you check the codes?

 

When I check the codes with a scanner there's nothing stored in memory ..

 

I found the circuit board on the instrument panel having (3) 100.J ohm resistors burned will let you know when repaired...
