Check engine light

I know it's posted but I just bought my 97 4.0. How do I get it to display the codes?

I ask because I tried turning the key on and off and on and off and on. Do I have to start the jeep the whole way up first? I got nothing.

97 4.0 with 5 speed

"Missed it by that much" as Maxwell Smart used to say.
On our 97, it's on/off, on/off, on/off very fast, then back to on.
Then you wait a couple of seconds, the odometer will blank out, and you'll get a code, then the odometer comes back on for a few, then the next code pops up, and so on.
97 Sahara, 74 Renegade, 72 CJ5, 55 Willy's (the Beast) Boss 302, 6:34 gearing, Bose 901 speakers.
God I miss that Jeep. Forgot the kinda Jeep, 80 SX4.
