What does OBD-1 or OBD-11 mean for reading error codes? What type is used for a 1993 honda accord? Where is the gauge cluster and the malfunction indicator lamp located on my car? Does it also mean that you are not hooking up a scanner to the ECM?

On-Board Diagnostics I (OBD-I), which is what you have. Therefore, you can't use a scanner. Here's what you need to do:

Service Check Connector (SCC): Reading OBD-I Codes

When the Check Engine Light (CEL) is on, it will be necessary to locate the 2-pin Service Check Connector (SCC) on OBD-I (pre-1996) Hondas. It is normally located under the dash, approximately 1 inch (2.5cm) from the right kick panel. Take a small screwdriver and carefully pry it from the rubber mount. The other 3-pin connector in the rubber mount is the Data Link Connector (DLC), which should be left alone. Jump the SCC with a paper clip, turn the ignition switch to ON (Position II), and count the number of times, if any, the CEL flashes. Reference a Diagnostic Trouble Code (DTC) chart to identify the code being displayed.
