How to:ECU Reset,Throttle & Accelerator Position Learning

[baseballfanz]

OK maybe stupid question but SES and CEL is two difference thing right? I can see my SES light but can't find the CEL light. I looked all over the instrument cluster but can't locate it. Where on the cluster is it? I try the ECU reseting procedure but can't seems to get the CEL to blink. Thanks.

SES/CEL one and the same.

Timing is everything to get this to work. Instead of starting the drill with the key turned all the way to off, try starting it from the position just before "ON".

Meaning don't turn the key as far to start the 3 second count.

Work great, thanks.

Here's a word document for anyone who wants a nice formatted procedure list.

Thanks, Phillip...much easier to read.

That;s what I did, copy to word document send it to my cell phone and read off that while in my truck.

Here's how I do it:

1. Turn ignition to "on"...count in my head, one thousand one, two...three.

2. Throttle pedal 5 times hard and fairly fast....THEN I start the 7 second count with a stopwatch beginning as soon as the pedal is fully released the 5th time.

3. At 7 seconds, push the pedal fully and hold until the stopwatch hits about 17 secs (total), the SES light should start flashing.

4. Release pedal as soon as you get the SES (17 sec) and then wait until the stopwatch hits about 27 sec (total) then push it to the floor again and hold until the stopwatch hits about 37 sec (total), (I hold until 40 for good measure), then release pedal and turn off ignition. Done!

If you don't get a flashing SES at step #3, then start over.

I've done this whole procedure a couple times just counting in my head, but you'll have better success using a watch.

I tried and tried and just couldn't get it to work. I have never had any success with it on my Spec V either. Pisses me off but my timing has got to be off somewhere.

[WindsorFox]

I can't get this to work either....

[WindsorFox]

Maybe it was a fluke, it finally worked. I wonder if it really reset....

[yellowv]

Got it to work. For all you guys that can't get it after pumping the pedal 5 times wait 10 seconds instead of 7. Worked the first time I tried waiting 10 seconds. Thanks Whistler

Is it normal for the Sevice Engine light to flash when the directions say to rev the engine a few times? It is only on at a high rpm and comes on for less than a second and turns off til the engine revs agian. After 10min though when I revved the engine, it didn't come on. I'm worried my timing is off now or something. Although the light doesn't come on anymore

The truck isn't supposed to be running when you do this. The ignition should be in the "ON" position. This is when the engine isn't running but you have power to your instrumentation.

I did the following:

Idle Air Volume Learning (Throttle Position Learning)

It is better to count the time accurately with a clock.

Operation Procedures

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

Now look at step 10.. says to start engine and I waited then on step 12 when I reved it the check engine light would flash when I reved it. Then after about 5minutes it didn't do it when I reved.

Did it today. Seems to have a little more pep in the low end...
