Actually if it is under the seat, no need to remove cover to see codes. There is a little door that flips open to see LED flash codes.

Sorry I can't find any other location except under the drivers seat.I just spent 20 minutes looking thru my chilton's before I realized it only goes to '88.Sorry I know how frustrating this kinda thing can be.Good luck,Matt :cheers:

Well, I hate to be the bearer of news.. but as according to my 1989 Honda Accord Service manual, the Honda PGM-FI ECU is located underneath the Driver's seat, closest to the door... the other, smaller box is the shift interlock control.

You should be to check the ecu for codes but flipping the seat forward and pulling it all the way forward

hmm......... it has nothing to do w/ being an sei, all our ecus are in the same spot and i think all the ones for injected cars are the same. oh yeah, its under the seat.

OHHHHH !!!...that must be the SPESHUL ECU, only came out on 4, count 'em, 4 unique SEi's that excaped the Honda skunk werk testing grounds. Man, those suckers were so special, they put the ECU in between the headliner and the roof (behind the moonroof stops)..they did this to to get precise lateral accelleration read-outs, and beam all info to a sattelite tracking station, which was hooked directly into the Honda mainframe computers, whereas, enginears could relay signals back to the car to adjust fuel pressures (individually to each injector), spring rates, shock valving, and calibrate the Bose sound system for noise atenuating frequencies.

To get any code from this ECU, you have to measure 27MM behind the dome light in the car, then find exact center between door panels, mark it, and then place a strong magnet up against the head liner (Honda recommends using dielectric lube to get the full magnetic field effect for a proper code release signal). Now turn the key to the 'on' position 6 times in 6 seconds, and the code will digitally come up on the hidden LED behind the clock on the dash. (oops, I forgot to tell you to remove the clock also). Once the code is processed, the LED will ax if you want to fix this problem, or continue driving, with errors in the system....
The rest is up to you.

..sorry, couldnt help it......move the drivers seat all the way up, and lean it forward. put yer head virtually on the floor, and you will see it (plastic cover with a small door about one inch square), pull the door open from the top down to the floor, turn on the ignition, and you should see a blinking red light if it's flashing any codes.
