VCFRONT_a165_unxpctdEFuseLckout
Description
The front vehicle controller (VCFRONT) detects an eFuse lockout is active (via voltage measurement of the lockout circuit) when the right vehicle controller (VCRIGHT) is not reporting an eFuse lockout is active.
Condition
The VCFRONT detects voltage on the eFuse lockout circuit (nominal 5V on eFuse lockout circuit for 2 seconds) when VCRIGHT has not reported the lockout circuit as active.
Clear Condition
The VCFRONT eFuse lockout circuit voltage measurement indicates an eFuse lockout is no longer active, and the VCRIGHT is not reporting an active eFuse lockout.
Potential Impact
If the eFuse lockout circuit is enabled unexpectedly, VCFRONT cannot enable or disable the low voltage (LV) power feed to other controllers. Vehicle features and functions relying on power supply via VCFRONT may be unavailable. Vehicle software updates may not complete successfully.
