Silverado-Security light solid-dead battery
I have an 02 Silverado LS 4x4. When I close the door the yellow security light stays solid. When this happens it will drain the battery in two days. Also With the key in the on position, either running or not, the air bag light stays on, the ABS light stays on. The Security light, Battery light, Service 4WD, and Low Fuel lights will cycle on and off the this order. The fuel gauge does not work and the Temp gauge does not work.
The truck runs fine, cranks fine, and all other accessories work. If I plan on letting the truck sit for more than a day I have to disconnect battery.
I have tried disconnecting the battery, did not help.
I closed the door and reached in and turned key to the on position and let sit for 10 minutes, this did not help.
Does anyone have any suggestions?
