Speedometer reading wayyyy off

[Travisstorbakken]

So I tore apart my dash the other day to try to replace one of the lights on my gauges. I unplugged the cluster and it all goes limp of course. I plug it back in and the speedometer pointed directly down and the fuel gauge went past E in the wrong direction. They both still work but obviously not showing correct. How do I fix this?

That pic of my speedometer is actually me traveling approximately 65-70 mph

Was The Ignition switch in On/run position when you unplug it

was the battery disconnected when you began the job ?
nevermind,
disconnect the Negative Post from the battery & reconnect it after a couple hours, hopefully something will reset itself

 

[Travisstorbakken]

Nope to both inquiries above… didn’t think anything of it honestly. I just figured the speed sensors would reset it

If I remember correctly, you can try to do a reset on the cluster. Press and hold the odometer reset button and turn the key on, in a few seconds it will start to go thru a self-test. Release the button and let it do its thing.

So I tried the reset. It did the whole scan thing and thought it almost worked but sadly fuel gave and speedometer is off just the same

If it is not the connector seated correctly, a bent connector pin or two, or off by a pin, if that is even possible, then somehow the DIC was damaged.

So I read that those cluster codes are like out of date or indeterminate of lrettt much anything those trucks..
