OBD1 Hardware Differences

EDM0 OBD1 Civic Integra0 ECU0s generally lack several sensors and circuits commonly found in USDM0 models:

They typically resemble USDM0 ECU0s but with fewer populated components on the circuit board.

OBD2 and Beyond

After 1996, EDM0 Hondas utilize the OBD02 family of ECU0s; however, they are not OBDII diagnostic compliant. These units feature only a 3-wire DLC0 and communicate exclusively with PGM testers.

EOBD (European On-Board Diagnostics) is the next generation of diagnostics. All petrol-powered road cars and light trucks manufactured after Model Year 2000 must comply with this standard.
