C6 Corvette security system light
I have a 2006 C6 Z06. The battery died the a few days ago. I was able to recharge it and the car runs fine but the security system light is on. The driver window is down and I cannot raise it nor can I lower the passenger window when the security system light is on. How do I reset or get rid of this security system light?

Good questions, I know other will post, but if your battery went dead, how old, you just might need a new battery, cause these cars when the battery gets weak does strange things.
If you change it, let it sit for 15 minutes without hooking it up, then get in close the doors start the car and index the windows.
More than likely everything will reset itself. You have to remember the windows go up on down with module?

Battery is a new odyssey extreme, only 3 months old. Car died because I was rushing home and left the headlights on. Now this security light is on and the windows will not go up or down so I can’t index them. Thanks.

If your battery was completely dead, it probably ruined it. If I were you, like previously mentioned, try disconnecting the battery for 15 min. then reconnect it, this may reset things in the car and take care of your problem. These cars electronics can do weird things when there are battery issues, and often disconnecting then reconnecting the battery to reset things can address these issues. If it fixes it, great, if not then I'd look into buying a new battery.

As has been mentioned disconnect the battery for 15 minutes so everything discharges. When you hook it back up the system will reboot. Index the windows and maybe it will be fixed.
As to the battery it can be trickled back to life. If you don’t have a charger take it to a battery place and see if they will charge it for you and test it. I have numerous batteries I could not bring back to life but a battery store could.

Just wondering if you have another issue. The headlights should have turned off by themselves after a few minutes. Mine do when I leave them on. Here is a clip from the owner's manual:

I just tried the 15 minutes off then hooked it back up the car turned right on battery still shows full on my ctek. However I still have the security light on the dash. I can lower the passenger window only through the passenger door. I can’t use the driver door controls to lower or raise either window.

Typically I drive alone.
I drove the car last night for approximately an hour and the security light turned off. My windows work fine now and everything is back to normal. I drove it this morning again everything is working normal. However, if anyone know of a way to disable or reset the security light without having to drive the car for an hour please post it here so others with similar issues can get their car running. Thank you.

I did a little research on this and really could not find anything conclusive as to what is causing your problem. Based on the threads I read through it could be a number of things and coincidental to the battery dying.
- If you have access to a Tech II to read the codes it would at least give you a starting point on what is wrong.
- You said you left your headlights on and that killed the battery. The the lights will time out after 20 minutes unless the car was shut off and then the lights turned on. So something is going on there and may be the cause of your issue. This has already been mentioned in this thread.
- The owners manual states that if the service light is on with the car running it needs serviced.
- Your battery could be bad since it completely discharged. You can test each cell with a Hydrometer and see if a cell is dead. The battery can check good with volt meter but actually not be any good.
- It was also asked of you if you have passengers. Reason being the BCM is behind the foot panel on the passenger side. I did read one thread where someone experienced your issue out of the blue with security light and windows not operating. Turned out the BCM pins were not making good contact. So you might want to pull them out and inspect/ clean. I would disconnect the battery in messing with the BCM as it you get an arc and fry it you will have a bigger expense.
- Have you tried simply locking the car with the fob, wait a minute and unlock with the fob? Could be the security system is just confused. Worth a shot to see if anything changes.

hate to bump a 3 year thread, but im having this issue. I replaced my head unit and battery terminals a few months back, but never started the car up because its winter. So I started the car up today because its nice out and was going to take it for a spin. Now the security light is on and I cant roll the windows up from the drivers door. The passenger switch will roll up the passenger window, but the drivers window switch, mirrors and memory seat buttons are not working. However, the drivers door release button does work. I checked the BCM connections and didn't see anything out of place (I was in there when I wired the back up cam power). I'm going to replace the battery tomorrow, its 7 years old, but always on a battery tender. I did not see a fix for this from all the searches I did.

Since the problem was not present before you installed a new head unit that is the first place to start looking. Maybe some wiring is not hooked up behind the console or this new head unit is not playing nice.

Definitely possible. I had a 6 year old battery that seemed to work perfectly. I kept it on a battery tender this winter and even started the car a few times with no issues. One day when the temps got even colder that battery tender indicated that it was trying to charge more, i.e. it couldn't attain a full charge any more. The battery was too dead to even roll a window up. An old battery can fully die even when on a tender.

Just don’t forget, you’ll have to reindex your windows after replacing the battery.

new battery, no luck on the windows,locks and mirrors working. Strange thing is, when I have the car in the on position ill get the chimes that the drivers door is open. Then after maybe 10 seconds it stops and starts back up again. Does the head unit have anything to do with the theft system/security?
