94 Accord

The service light came on and stayed on (no flashing, etc.) in my son's 94
Accord - Firestone didn't have the right connector to plug in to his car and
diagnose the codes. Now the other service light is on, too - again, steady
on, no flashing - the car seems to be running fine - any suggestions before
I send him to the dealership?

 

I'm confused - are they the "service due" light and now the "check engine"
light?

Go to Autozone. They will read the ODBII codes for free for you.

 

Your car is NOT ODB-II, so nobody will be able to pull any codes using an
OBD-II reader.

Instead, you need a sophisticated piece of hardware known as a
"paper clip". You use the paper clip to short two pins together in the
Service Check Connector to make the Check Engine light flash.

See here:

specifically page 15.

Report the code(s) back here.


As for the other light, it must be the Maintenance Required lamp. You can
reset it here:

except that OBD-II didn't happen until 1996,he has a 94 model;OBD-I

all he needs is to jumper the two-pin connector(near ECU) and the ECU wll
flash the codes at the CEL(check engine light).

 

I couldn't tell from the diagram in the reference manual - does the
diagnostic connector plug have just two pins that I short out with a
paperclip, or are there more than two pins - if so, which pins get shorted
to get the codes. THANKS VERY MUCH FOR THE HELP!!

 

Dig out the connector and look at it. It's only got two pins.
