I was also curious about this.
Maybe the keyless entry computer stays awake to try to sync with a fob and then sleeps on success? If a user chooses not to use a fob at all, maybe it stays awake indefinitely trying to find a key to sync with.
- Captaffy 3y agoFrom my own experience I believe the issue is that when these modules start to go bad they fail to turn off and stay awake indefinitely.
- blobbers 3y agoYeah sleep-wake problems often are related to things missing or broken in the (poorly constructed) system. If the software on the car was poorly written, it may not have had a good back-off on the fob check, or if the fob itself was malfunctioning it may have left the car in a weird state. While I wouldn't expect a fob to drain a car, it certainly doesn't seem implausible, especially given what the fix is.
