Speedo Calibration help pls

[Tx_Atty]

I ran through the instructions to recal my speedo tonight and got the sweep and some display,then pressed reset and got the current code (although the instructions say it will say "recall" it said 984CAL). I assume 984 was the current code. So,I press SELECT like the instructions say but nothing happened. It is supposed to scroll through codes until I get the right one but not happening.

Im leaving for a long drive tomorrow and would like to have the speedo correct. Can anyone tell me what Im doing wrong? I have the PSOM grounded, I think anyway.

Thanks!

To set the calibration, ground the single wire connector under the glove box that says PSOM (Programmable Speedometer Odometer Module). There is only one and it has a spade type plug on the end.

* Next look at your speedometer while sitting in the drivers seat and there should be a "reset" button and a "select" button.
* While holding the "reset" button in turn the ignition to "on" then let go of the "reset" button.
* The speedometer display will sweep once and will show a code. Now push in the "reset" button again and the existing code will be displayed with RECALL.
* Now you enter your new calibration code by pushing the "select" button until it gets to the new calibration code number.
* You may have to push "select" a whole bunch of times until you get to your code. If you turn off the key at this point the original code will not be changed.
* To store your new code press "Reset", turn off the key and unplug the ground wire under the glove box.

Don't forget that you can only change the calibration 6 times without replacing the module and the previous owner may have already had it done a few times.

the PSOM connector is the brown single wire plug that is clipped to the underside of the dash under the glove box.

yeah, I got that grounded. the problem Im having is that the Select button doesnt do anything after I start trying to scroll through the codes. That is where Im stuck. Any idea why it would not scroll?
