Question about 2004 Chevrolet Silverado
Bet it was set off and is why your battery ran down. Have had this happen before when jumping dead batteries.

Testimonial: "Sounds reasonable. I'll see whether the battery is O.K. in the morning. Thanks!"
I fear there might be 3 problems and you have to exclude them one by one. Check battery termminals with a multimeter. With engine off should be 12.6 Volts or more. If not, then you need a new battery. With running engine should be at least 14Volts. If not, then you have charging system trouble. A stop at Autozone cand read engine codes, give you a print out explanation, and check the alternator for free.
You might have an battery leak. This is more difficult to diagnose. Disconnect the wire harnes from positive terminal of the battery, and conect a 12V / 1 amp bulb in serial. Avoid sparks, using aligator clamps, or computer might be damaged. The system will source 1 amper current because computers are switched in learning mode, but after 10 - 15 minutes the current should dropp in milliampers. If not start pulling off fuses one by one. If light turned off you find the problem. To find the amount of leak replace the bulb with multimeter set at 10 Ampers mode, you have to vait at least 10 minutes.
If security light is on, disconnecting the battery for 30 minutes and connecting a good battery, normally clear the code. In some old cars locking up the car and and unlocking the driver door with key temporary cures the problem. If security light goes on again you have to go to the dealer for a check and advice ONLY. This will cost you $65 to $100 but you vill get a good answer. Thousands of dolars diagnostick systems can be afforded by big dealers ONLY. Hope this might help.
