Turn the key from the off position to the run position(not all the way to start) when the system makes one beep turn it back to off. repeat three times. this will reset the obd II computer. if you do this correctly the odometer will read some words like reset or something

I had this same problem, I replaced the gas cap, disconnected the battery to "reboot" the system and it hasn't come on again.

1996 Jeep Cherokke 5.2 grand laredo, missing on acceleration found loose distributer need to set timing.

Base (initial) ignition timing is NOT adjustable. Do not attempt to adjust ignition timing by rotating the distributor. All ignition timing functions are controlled by the Powertrain Control Module.Adjusting the timing on a Jeep Grand Cherokee requires special tools and an understanding of engine mechanics. Changing the timing on a Jeep Grand Cherokee with distributor-less ignition requires professional reprogramming of the powertrain control module. This guide covers Jeep Grand Cherokee models with distributed ignition only. you can go to this site and it will explain it. have a good day !!

My check engine light activated on my 2001 Jeep Grand Cherokee Laredo - what does it mean?

All modern cars have this generic info light. You have several options:
1) Free (sort of) most oil change places can check it.
2) Buy your own OBDII scanner, about $100 bucks, works for all '96 and newer cars. Gives peace of mind that YOU know what is wrong even if you can't fix it.
3) Take to mechanic and hope they are honest and don't take you to cleaners.

Generally this light is tied to the emissions systems. Your car won't pass a smog check but it may run just fine. If you are capable check all your fluids especially the oil. Good luck.
