Conditions for Setting the DTC

B3920 00 

Current out of the module does not match the current returning to the module from 1.5-5A.

B3920 01 

The voltage on any power rail1 motor control circuit exceeds 2.78V for 100ms.

B3920 02 

The voltage on any power rail1 motor control circuit is below 1.47V for 100ms.

B3920 42 

This DTC will set if the module calibration is not programmed.

B3920 0B 

The differential current measured through the high and low side of the power rail is within tolerance of each other, but the absolute current or an over-current has exceeded the maximum value.
