Hi Yen,the usual reset is key on, press the throttle 3 times wait for the light to blink,key off,key on and light should be off.
Customer: replied 8 years ago.
Tried that...pressed the throttle three times with key on and no blink (I tried that because that is reset procedure for newer pickups). This is a CAT c7 Accert motor with Allison automatic trans...might need to be hooked up to computer to make light go out? Tried to hook up my Snap On scanner to OB2 connector and went into Generic setting and computer won't communicate.

I am like you with the standard reset,we have an 02 without this feature.Can not think you have to hook up to a scan tool to reset.My books only go to 03,do you have an owners manual that may be of help?
Customer: replied 8 years ago.
Bought truck used with out owners I purchased the service manuals and they say that this info is in owners manual...go figure
Expert:  daves71 replied 8 years ago.
Sorry,just have to laugh!Buy the expensive service manual and it is no help!I'm going out to check our 02 manual to see if its any help.
Expert:  daves71 replied 8 years ago.
I went out and checked our 02,same thing key on press the throttle 3 times(have had to really press the throttle hard before)light should flash.
Customer: replied 8 years ago.
Does your 02 have a throttle cable? This machine is fly by wire (no throttle cable...pedal hooked to sensor)
Expert:  daves71 replied 8 years ago.
Yes ours is fly by wire
