Recalibrating Instrument Cluster

[WeezyRT]

I need some help recalibrating my gauges. I came across a write up that said to hold the odometer trip button then to turn the key to the ON position and to hold the trip button for 10 seconds and release.

The needles are supposed to move to three different positions then return to "relaxed" but when I did this, nothing happened. "CHEC" appeared in the odometer screen as it was supposed to but nothing else happened.

Any ideas or tips?

Also interested. Did u pull the needles or gives at all?

Yes, I pulled the needles.

I reinstalled them where I THOUGHT they went but I clearly didnt get them right.

The tach and speedo dont even move at all.

u gotta cycle the key on and off 3 or 5 times

Could you be a little more specific?

Do I need to do this while holding the odometer trip button or.. what exactly?

You don't need to cycle the key three times. That's for trying to check for codes. You are doing it right by holding the odo button in. If the guages aren't moving, it sounds like you probably pushed the needles back on too far and they are hitting the guage face. Try pulling the needles out just a little bit to keep them from sticking and try again.

Start the sequence like told (hold the trip reset button and turn key on); after the needles flatten out for their calibration test, the indicated markers in the photos are for each stage of the sweep. You'll have to run through the sequence multiple times to calibrate each gauge.

Thanks guys.

Going to take a few more small adjustments but its getting there and they're moving.

Easiest way I've found to set the speedo and RPMs is to do it with the truck running. If you have some sort of OBD2 reader where you can see the RPMs of the engine on your laptop or scan gauge, then just set your RPM needle based on that. If you have a SCT tune, ask whoever wrote the tune what your idle RPM is. If it's stock, I think it idles at 650rpms. Then once you get the tach needle set, go for a drive. Find an open road with little traffic as you are going to be placing the needle on while moving. With OD on, and stock gears, 60mph is exactly 2000RPMs. turning OD off at 60mph the RPMs increase to 3000RPMs. You can use that to check the accuracy of the needles. It's hard to get the needles pushed on during the self test before it moves to the next position. The battery voltage, fuel level, oil pressure and coolant temp are also easier to do if you just remember the position they are normally in when driving.

Thanks for the tips :biggthumpup:
