Alert description

The battery vehicle controller (VCBATT) detects an eFuse lockout is active (via voltage measurement of the lockout circuit) when the front vehicle controller (VCFRONT) is not reporting an eFuse lockout is active.

Potential impact

If the eFuse lockout circuit is enabled unexpectedly, VCBATT cannot enable or disable the low voltage (LV) power feed to other controllers. Vehicle features and functions relying on power supply via VCBATT may be unavailable. Vehicle software updates may not complete successfully.

Set condition

The VCBATT detects voltage on the eFuse lockout circuit (nominal 5V on eFuse lockout circuit for 2 seconds) when VCFRONT has not reported the lockout circuit as active.

Clear condition

The VCBATT eFuse lockout circuit voltage measurement indicates an eFuse lockout is no longer active, and the VCFRONT is not reporting an active eFuse lockout.
