I was wondering if there was a way to check the MPEM on the skis. I bought a 99 XPL to part out (it was in a wreck and sat for a couple years) . When i put the key in I dont get any beeps but the gauges light up and VTS work. Is that enough to say its working? Im pretty sure the buzzer is broke since it doesnt beep at all but I was just wondering if 1, the key is the right key, and 2 if anything else had to be checked to consider it fully operational.

Any help would be greatly appreciated!
