ive got a check engine light on right now, and i tried jumping the little wires under the glove box area, and nothing happens. And its not just with this swap/ecu that i havnt been able to pull the code...

its always been that i found out manually/visually what was causing the check engine light and resolved it like that, but now, ive got a check engine light on my fully built b16, and i still cant pull a code!!

is there a particular pin on the ecu that could be grounded or something similar that would achive the same effect as paper-clipping the jumper?

thnks advance for ur input and advice

 

which car?? ecu?

 

car is a 92 civic hatchback cx. with a p30 ecu right now, and a b16 motor

i had the same problem with the p28 ecu and d16z6 back then.

and even when i had the crappy stock motor.

its obd-1 eg6 now.

thnks

 

u sure ur jumping the right one..? i think its the gray plug, or whichever on has 2 slots, theres one with 3 next to it...both are held in a green rubber thingy..take it out..

 

yep, positive im doing the right one.

in fact, on my car its weird, it dosnt have the little harness w/ 3 wires like most obd-1 civics/del sols ive seen, mine just has the 2 wire plug only, its not accompanied by any 3 wire plus like most others...

dont know if that means anything, but thats the situation.

 

weird...

 

im stumpt hardcore, cuz i need to pull the code

is there a pin on the ecu that can be jumped that would accomplish the same thing this little 2 wire plug does?

 

I pulled out my trusty 1993 Civic Helms, and according to the manual, you should jump D4 to D22. Make sure you have a solid connection.

 

thanks so much for the info bro! ill try it out tomorrow!

ill let u know how it worked.

thanks!

 

ok, when i 'pull the code' the check engine light just stays on solid, i waited for over 30 seconds and it just stays on solid. is there anything i should do in series or by patter to pull it properly?

i put the wires in place, and turn the ignition to on position without starting the car - and the light just holds solid.

 

I think that means there are no codes. Here's a bump anyway. Maybe someone will confirm.

 

yeah when the CEL stays solid while you jump it, it means that there is no code. dunno why your's is staying on...

 

My Helm book ('95 Integra) says code 0 is when the ECM is bad.

Never happened to me, so I don't know if that's indicated by a CEL that stays lit or stays off...
