On your OBD1 PR4 ECU's, when you jump the ECU, what does your check engine light do? Does it come on and stay solid? Fill me in...

 

Bump, please help!

 

Nobody knows?

 

Answers are a blessing...

 

Well Id say search a little ya might get flamed on for a simple question, but its simple, depeneding on your code it flashes 1 fast for 1 and one long flash for 10 so say if you had a code 13 it would flash 3 times fast and one long for 10

Checked up on that according to Helms and Honda-Tech and didn't really find a good answer. So I'm checking to see what happens to ya'll when you put a jumper in the harness.

The CEL does not flash...it just stays on solid. (when jumped)

 

Word?

 

the light stays on solid for a second then blinks, you count the number of blinks and you have your code.

 

No, but it wasn't ever blinking. It would come on and stay on solid.

Found the problem, though. Ignition coil was going out...and there's no error codes for that, LoL.
