How to:ECU Reset,Throttle & Accelerator Position Learning - Page 6

I can't get my ECU to reset in my '04. I've tried the easy method about 20 times over two days now and still no luck. I just can't get the SES light to blink. I've used this method before and had success but something's wrong this time. And after every time I try and fail, when I step on my brake pedal in order to put the truck in drive the pedal is really spongey and goes all the way to the floor while making a sound like air releasing. I was afraid that I had no brakes but once I start to drive the pedal feels normal and the brakes work fine. Anyone have any thoughts on what might be happening?

I tried this and after i hold the pedal down for 10 seconds the SES starts to blink but then stops after a few seconds. Should I try holding the pedal down longer? Anyone have an idea why the SES light does not continue to blink?

If you only get 3 sets of 10 blinks, the ECU has no codes. If it starts to blink and then stops, there could be a problem with the communication between the ECU and SES dash light. Be sure you do not hit the accelerator or turn the key or the test will stop.

Guys, i need some help. Tryed to reset my ecu yesterday and couldn't get my check enging light to blink so i tryed it again. Now i have a blinking red light with a wrench in the center of it just above my speedometer. I've read the owners manual and can't find the purpose of this light. Can anyone identify this light and can i clear it? I think the reason i couldn't reset the ecu is because i have a active tire pressure light. thanks

Tire pressure light doesnt matter. I dont have mine in my aftermarket rims so its always on. Try the procedure with a stopwatch. do the one called the "easy method". Time isnt as criticle. or go to autozone and get the code read and cleared for free. If the light was on before you should read it first rather than clear and ignore.
