Oh boy, it's been some time since I had a '92 so rather than embarass myself, I'll defer to someone who has one or remembers. As a last resort, you can pull battery power.

Hello...
Enter diagnostics by pressing "off and warmer"
Once codes have displayed, press "off and fan up" to clear codes
Then press "econ" to exit
Post back when you have cleared the codes.
