Here is a guide that will help,
Usually, when the codes are cleared, that resets the mil, but, if the problem hasn't been corrected, it will come back on. If there is a special procedure for your vehicle, I'm not aware of it.
On obd1 vehicles, I'd take the negative battery loose, to erase the codes, before I got a scanner. When you take the battery cable loose, you lose any memory settings like the clock and radio. You can also lose computer memory, like engine run parameters. The engine may not run as well until you do a relearn procedure or drive cycle. I'm glad you got it.
