ClubLexus - Lexus Forum Discussion - Checking Engine Codes on OBD1

Hi everyone! I searched but can't find the answer. How do you check the codes on a 1992 Lexus ES300? So far, I got this:

Quote:

"To find out the problem source of the Check Engine Light:

Make your the engine is at operating temperature & shut it off.

Get a jumper wire, and at the diagnosis modeul (engine compartment, near the drivers side strut) Connect the "E1" & "T" terminals.

Turn the ignition to "On", do not start. The engine light will blink a code.

Tell me that code, and I'll tell you what to look for."

Is that correct? Also, where do I find a list of the what the codes mean once I get it from the ECU? Thanks!
