SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

I had this problem on my '03 Yukon. There is an IC or other component on the dash/gauge panel that went bad, but I pulled the gauge cluster and sent it to mrwhizard.com. They replaced some parts, and i paid to have the stepper motors replaced as well, since they would prob go in the very near future. I want to say it cost me about $150-$180 total, including s/h, and had it back in a week or so. It retained my original odometer reading as well, which I was very curious/cautious of.....
Good luck.

SOURCE: Need to reset oil life

it depends........ if you have controls on the steering wheel or not. If you do, then go through the menu until you see OIL LIFE then hold in the reset button (looks like a backwards "L" with an arrow on it). Hold the reset button in until it reads OIL LIFE RESET or OIL LIFE 100%. If you don't have controls on the steering wheel, turn key on (engine off) and depress the gas pedal to the floor 3 times, now turn key off. crank engine up and see that it has reset, if not try it again.
