C-Fizzy Posted December 2, 2010 Report Share Posted December 2, 2010 Ok, long story short, i was trying to reset my check engine light yesterday so my car could hopefully pass smog. I disconnected the negative terminal and let the car reset. That didnt work. So my dad took a paper clip, and jumped two prongs insider of the diagnosis box, the light went off, but when i went to start my car, it didnt fire. It turns over, i'm just not getting a spark from the plugs. and before any of you ask, its not a battery problem, and the car was fine before he jumped the two prongs. anyone here a mechanic?

cOmpressor Posted December 2, 2010 Report Share Posted December 2, 2010 Did he know what he was doing? Seems like you could have damaged the computer. Also have you checked the fuses under the dash and hood? Quote Link to comment Share on other sites More sharing options...
Rebel4055 Posted December 2, 2010 Report Share Posted December 2, 2010 Jumping the 2 pins on the diagnostic terminal is only for in my knowledge cars that are older and you can't use a diagnostic tool. I never heard of doing that to clear the check engine code. Quote Rest In Peace mother.

skittlesRgood Posted December 2, 2010 Report Share Posted December 2, 2010 take your dash apart, put electrical tape over the light, assemble dash. as for the jumper... is it still in there?

C-Fizzy Posted December 2, 2010 Author Report Share Posted December 2, 2010 He's jumped two pins before to clear it, but i dont think he jumped the right pins. Which fuses could affect the car not starting? i could only think that we blew the ecu fuse or the whole ecu for that matter. @skittles, no we removed the jumper.

Rebel4055 Posted December 2, 2010 Report Share Posted December 2, 2010 (edited) If you decide that you have what you need to disconnect the battery and would like to reset the check engine light by doing so, there are a few more tips that I can provide.Most vehicles from 1996 and newer have a stay alive memory built-in to the computer system. When you disconnect the battery from the vehicle to reset the check engine light. The computer will be able to hold the memory and the code for several minutes and in some cases several hours. Battery voltage is stored in a capacitor and is supplied to the computer to keep the memory alive. The way around this is to disconnect the battery and then hold down on the horn button. Found that and all I can think of is to check ALL the fuses to make sure. What kind of car is it? Edited December 2, 2010 by Rebel4055 Quote Rest In Peace mother.

Rebel4055 Posted December 2, 2010 Report Share Posted December 2, 2010 I tried looking for the terminal pinout online but I can't seem to find it... Will keep trying. Lets hope he didn't cross the wrong pins. Stupid question but did the service engine light go off? Quote Rest In Peace mother.

melonhead Posted December 4, 2010 Report Share Posted December 4, 2010 I know I'm late to the party but I think you can just use a code puller to pull the code and it clears it for awhile at least. My check engine light was on my 2002 VW Jetta and would not go away even though nothing was wrong with the car. I used a code puller to clear everything and drove that bitch to the dealership to trade that POS in. Quote Link to comment Share on other sites More sharing options...
