VCFRONT_a164_eFuseLckoutMissing
Not Available
What does the VCFRONT_a164_eFuseLckoutMissing alert mean?
The front vehicle controller (VCFRONT) detects the voltage on the lockout circuit is not high enough when the right vehicle controller (VCRIGHT) reports the lockout circuit active, indicating the eFuse lockout is not successfully asserted.
What you'll see in your Tesla
- Not Available
What triggers it
VCFRONT detects the voltage on the lockout circuit is not measured at 5V over 2 seconds when VCRIGHT reports that the lockout circuit is active.
When it clears
VCFRONT detects that eFuse lockout is no longer asserted or voltage detected on the lockout circuit is greater than 2.5V when measured over 2 seconds.
Potential impact
No functionality should be directly affected when eFuse lockout is missing. However, one or more eFuses may toggle between enabled / not enabled states if the VCFRONT is reset and its non-volatile random access memory (NVRAM) does not function as expected. Note: VCFRONT should not attempt to toggle eFuses via the enable line when lockout is asserted, even after a reset.
