VCFRONT_a248 — Voltage Out Of Spec

Full alert identifier: VCFRONT_a248_voltageOutOfSpec

Alert description

The vehicle controller detects a difference greater than 3% between readings from the two sensors that measure the low voltage (LV) battery voltage.

Potential impact

There may be some inaccuracy in the vehicle controller's LV bus and LV battery voltage readings. This could lead to accelerated LV battery degradation or an increased likelihood of alerts related to conditions caused by the LV bus voltage being higher or lower than desired.

Set condition

The vehicle controller detects a difference greater than 3% between the values reported by the two sensors that measure the LV battery voltage.

Clear condition

The vehicle controller detects less than 3% difference between the values reported by the two sensors that measure the LV battery voltage.
