thank you for your question hope this helps.

There is no diagnostic port for honda before 1996 and up due to OBD 1, you can pull the codes this way.

codes are read from the check engine light after the two-wire service connector has been jumped. the codes are read from the check engine light after the two-wire service connector has been jumped. On Accords, the service connector is under the dash on the passenger side.

Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14).
