Need little help
I Justed picked up a 02 Dakota 4x4 3.9
I attacked a abs issue but havent been able to complete it . Replaced passenger wheel bearing and sensor , replace pumpkin sensor. Abs light flashes non stop. Tried hard reset , Pulled battery and held key for 5 seconds . light back on after battery hooked back up.. So i pull the 40 amp fuse under the hood and now my abs light is solid and the brake light is on and solid . Getting confused
Why would both lights come when fuse it removed , but when fuse plugged in only abs flashes . Speedo has always worked .
Does this mean im leaning toward a abs module. I have scanners in my tool box that run abs/srs . It told me tone ring out of range thats why i replaced pumkin sensor . I have to this car inspected soon and with the light blinking im gonna fail . Can i pull the bulb or is it a circuit board Thanks for any and all of your help

The brake warning light is an LED on the cluster, not a bulb.
The warning light is not a simple switch, it's electronically controlled. According to the FSM it's illuminated when there is a fault with the CAB. Pulling the fuse will trip the light and the ABS lamp.
Why did you replace the passenger side speed sensor? Was it a bearing failure? There are really three tone rings.

relax man this one has me puzzled as well. What it sounds like to me is your truck isnt sure about your pinion factor (tire size) or axle type has not been programmed. Id contact the dealer ship about having your truck reprogrammed
