Instrument panel going crazy
 

Hey Guys,

Having some strange intermittent issues with my truck. A couple days ago the ABS and Brake lights came on the dash...ran the codes, said rear wheel sensor. Shortly after, my cruise control wouldn't work intermittently...the green cruise light went out and wouldn't turn back on at all. Now today the ABS and Brake lights went out, the cruise light comes on when button is depressed, the speedo quit and nothing happens when I push set for cruise control. Obviously something strange going on, looking for pointers on where to start looking.

Thank You,

Eric

Another piece to the puzzle tbis morning on my drive to work...I thought I may have been in limp mode, cuz my MPG was droPping on OTIS, BUT i could feel the downshift/upshift when pushing tow/haul. After a while, things went frantic, the ABS and Brake liights were flashing on and off and beeping while speedo kept jumping from 0 to 65 for aboit 30 seconds then held lights on and speedo at 65...then MPG started climbing back up. Occassionally at random the rest f the drive it's beep, flash the lights and drop speedo but went right back.

I would start with rear speed sensor and wiring

A little more to the story after today. It went back to speedo not working at all on the way home, I also noticed the odometer not racking up any mileage at all. Lastly, the fuel gauge kept slowly dropping and raising, not much, but I was a little low, to where the low fuel ding and light come on, it's slowly raise back up above the level and turn the light off, then a few min later drop back down to the level to set the dinger and light, then back up just enough to turn it off...NEVER has done that before either, but it knowing how much gas is in it, the gauge still seems to be pretty accurate it is just moving just enough to flirt with the line in which it triggers alarms.

do you still have functions like remote door lock sna key fob working how about interior lights coming on when the door is opened? does your radio work?

Yes, everything else seems to be functioning fine

did you try and hold the odometer button in while turning key on for ten seconds. I am not sure if the ram has a reset like that but the Minivans do.

I have a scan tool, I cleared the codes with that.

My Instrument panel wents nutso before and it was my battery. But it wont start.
