Hey Guys

I just need to know the correct way to reset my ECU on my 94 Integra.
Details Please!!!

 

In your underhood fuse box there should be a 7A radio back up fuse pull it out weight about 30 seconds and put it back in you should be set or should i say reset

 

I follow this procedure:

Simply follow these steps :
1. Turn on the car and warm it up, keeping it at normal idle level
2. Turn off the car an pull your ECU fuse, located in the fuse box.
3. Keep the fuse out for at least 5-10 min
4. Plug the fuse back in and close the hood
5. Now start your car, but do not step on the gas.
6. Idle the car for about 5 minutes
7. Last, shut off car then start it up again

sorry for being dumb... but what is the purpose of resetting the ECU?

 

People do it most often after a mod, such as intake, header, exhaust, etc.. It is so that the computer can make new data on how to manage the air flow, fuel, etc..

Also, maybe a major weather change is making the car run a little funny..resetting ECU then helps adjust much faster.

 

Disconnect the battery for .001 seconds.

 

is there any way that you will know its reset? or do you just assume?

 

you just assume. I removed the fuse, remove the neg battery terminal, and overall, I just assumed it was reset already. I sure think so.
But then again......"assumption is the mother of all **** ups"

 

So witch is it?

 

removing the ECU fuse or disconnecting the battery will reset the ECU, if you want to be sure of it you could connect an OBDII scanner to 96 and newer integras. It will show that the monitors are reset and not ready for a smog check.

 

This. Why do you guys wait 5 minutes before plugging your relays/terminals back in? Does the ECU have Caps in it to store charge or something?

 

First off, I am guessing it is pretty much impossible to disconnect the batt. or anything for just .001 sec.

At our shop, [Dave Ward Auto Electric] we disconnect the batt. to reset the ECU/ECM, [or any control "module"] for no less then 5 min, on most cars we disconnect both the pos.(+) and neg.(-) terminals and connect the terminals together to insure all cap, [wherever they are] are "drained", then the pos.(+) batt. cable is reconnected, then the neg.(-) batt. cable is reconnected.

This insures all "modules" are reset, there is no assuming. 94

 

disconect ur battery for 20 secs or just turn on your car rev it up to 5k turn the switch off and back on real quickly

 

Most people pull the fuse, just so they don't have reset the radio and clock.

Add revving the motor up? Get way for a backfire and ripping the teeth off the timing belt.

 

total BS

 

Cool beans. Good answer
