Thread: pulling OBD1 codes....

can i do it whils my motors is running or while its on the on position,but motor off?

my CEL comes on every now and then ,mainly when i stop(redlight),turn the car off then on quick, or just cruising.

but it goes away when i hit the gas pedal and let off....then comes on and goes away.


wen the CEL come on it blinks......that normal?

key on with motor off
turn the screw clockwase all the way and back counter clockwise to read codes.
Then to reset turn ****wise...hold for 4-5 seconds,and back counterclockwise again.
ou should get 55 if all is normal after resetting and driving .

yeah 5 short flashes and 5 long flashes, if there is a problem you will get a different number of long and short flashes.

alive from the dead.....

same procedure for a chipped ecu calum b13 basic?


anyone got a quick link to the codes?

same procedure

wierd thing is i thought so....and the red led just stays on....no reaction to the screw...

this fucking nx is running HORRIBLE right now....idk wtf happened...was like a BEAST 2 days agho....


im hunting for this goddamn obd1 cel lcode ist and cant find it...

get the code first and call me or pm I have a FSM to look it up for you once you have the actual code.

yeah man it wont pull codes....ive done this on my old nx...this ecu didnt blink. solid on...

wont reset or anything....disconected the batt for 5 min....re connected same shit

as soon as ignition on ,motor offf , key is on position, fans are on and the red led is on...

that dont sound good.Good luck with that...Maybe the ecu went bad?? dunno

Mine did that a while back. Turned out to be a bad connection on the + battery terminal. Sure didn't look bad to me, but after replacing the entire terminal with a new, higher quality piece, it's never happened again.
