OBD-0 CRX check engine light

[CB7tuner]

i just got this 90 CRX yesterday, it runs and drives fine but when i go over 70mph the check engine light comes on. it doesnt stay on, just when im at 70mph and above, its a stock d15 in it. how do i check the engine codes on this OBD-0 crx??? is it a jumper connector under the dash just like an OBD-1 car????

the ecu has a red light that flashes quick blinks=1 long blinks =10 ex. one long blink,one short blink =11 the google the cel number and it will tell what is wrong with the car...its very simple...gl




edit: here ya go......(the number represents number of flashes from the ecu error light)

Identifying the Fault Codes.

The number corresponds to the number of flashes.

yea the obd0 ecu's have a light on the ecu itself, just gotta read the codes

THANK YOU!! theres no such thing as OBD-0

You two are retarded, its not called OBD-0 or OBD0.. it was just called PGM-FI, OBD-I was the first time they used those letters.
