WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
For a description of the boost converter. Refer to DESCRIPTION .
The MG ECU uses a voltage sensor (VL) that is built into the boost converter to detect the high voltage before it is boosted. The ECU also uses the battery smart unit to detect HV battery voltage (VB).
HINT:
Using the Techstream, check the Data List of "Power Resource VB" and "Batt Pack Current Val". If these values are not within the below range, there is a battery smart unit malfunction.
