Question about 2005 Chevrolet Silverado 2500HD 2WD
Every time i start my truck it says service 4WD. and i wont let me engage it and let it switch to 4H from 2. its my plow truck and my way of income and it is a snow storm rite now. does any one know what the reset code is for the 4wd system on the computer?
Check ABS system for codes. I have an '03 Silverado and have a faulty EBCM( Electronic Brake Control Module, "ABS module"). Can't reset anything. Only replacement of EBCM will fix it. Incidentally, if you have to replace it, you can check on Ebay for a rebuilt unit. You shouldn't have an issue with your "base" braking system though, if this is the case. ABS is electronically controlled and with or without it, your brakes will still function. I hope this helps.

SOURCE: 04 Kia Sorento stuck in 4WD Low
Usually the vehicle needs to be stopped and in Nuetral. Flip switch to 4X4 HIGH firts. It should come off. If it does not, put in drive and start moving slowly. Once in 4X4 HIGH you should have no problems going back and forth from 4X2 and 4X4 HIGH.
It's not necessary to use the 4X4 LOW setting in a snow storm in my opinion. I only use it if I'm off road going up a really steep grade or if I'm hauling something heavy up a hill. I only used it once because I was hauling a 26 foot pontoon boat out of the water. I strongly recommend using 4X4 in a snow storm or on slippery surfaces since you will get much better traction.

Always make sure that whenever you engage into and out of 4x4, your gear lever is on N and not P.
so to reset it in now, switch on your engine with the hand brake up. set the gear lever to N, turn the knob to 4x4 Hi... wait 10 secs....switch it back to 2Hi...wait 10 secs and then return the gear lever to P and it should be ok.

check the solenoid on the front chunk these vehicles have had a lot of problems with these solenoids. have personally replaced about 10 of these on 98-02 models.
