Fuel Filter Reset

[Dan Przekop]

I Have A 2005 2500 Duramax, We Recently Noticed The Change Fuel Filter Display Came On . We Chaged The Filter, But No One Can Tell Us How To Reset It. Also It Is Not Covered In The Ownwers Manual.

Good question, but i dont know the answer but i will find out, not all of the trucks have the fuel filter life monitor on them and the ones that do i beleive the came with one of the ecm reflashes!!!

I'll see if i can get you and answer, unless some one else knows here?

Maybe just the sensor is dirty making the light stay on?

I Am Sure The Sensor Is Good, The Change Fuel Filter Display Came On As It Should To Tell Me To Change The Fuel Filter Just As It Is Suppost To. The Change Oil Display
Also Shows When It Is Time To Change The Engine Oil.
It Can Be Reset By Turning The Key On, And Pressing The
Throttle Pedal 3 Times To The Floor Quickly.That Is Doing Great.But We Still Do Not Know The Steps To Reset The Change Fuel Filter Display. Thanks, Dan.

This is the explanation i got from a buddy but i cant try it as my truck dose not have fuel filter life on it!!!!

FUEL FILTER LIFE RESET
This message will appear when a reset is performed either by using the steering wheel controls or the following manual procedure.

For vehicles with steering wheel controls, press and hold the select button for five seconds while the FUEL FILTER LIFE message is displayed. This message will appear on the DIC for ten seconds.

For vehicles without steering wheel controls, do the following:

Without pressing the pedals, turn the ignition key to the on position without starting the engine.
Wait five seconds.
Completely press the brake and the accelerator pedals simultaneously and hold for ten seconds. The system is now reset.
Turn the ignition key off.
The next time the engine is started, the message will no longer be displayed.

Let me know if it works?

hmm thats an interesting way I wonder how the brakes and throttel are tied to the sensor.

Boo (brake on off) and TP(throttle position) are both just imputs to the PCM and any other module chevy uses that requires thier imput. When the PCM sees an imput or a combanation of imputs, it has an output, weather it be to add more fuel, or to reset a light. You have to remember when thinking about electronics, its just imputs and outputs....they arent thingking "thats the trottle pedal or brake pedal being depressed".....

I registered on this site yesterday for this very topic.

I tried 05_LLY's recommendation, and it worked. Just note that the "select button" is the "return arrow". On my 05 LLY it is on the right hand side of the steering wheel.

Thanks for the help.

yes, what mschn99 said is spot on. computers think in binary so all they see is zeros and ones, or in many cases like gauges a varying voltage range. The computers are programmed to recognize certain combinations of inputs, and then have a programmed output for that specific input. For instance that fuel filter replacement message... as long as the readings from the sensor are in the safe range the output is zero (no replacement msg displayed), and when it needs replacement it sends a one to the part of the computer that displays that message, and the message shows up. Thats at least a simplified version anyway, I had to take dumb classes with all that junk, so unfortunatley I know more than I care to about it.

How many others have a filter life display? I have an '05 with the steering wheel controls and I have the oil life, but no fuel filter life? Or does this only come on if it senses that it needs changed? Thanks.
