Battery pack current sensors diverge too much
â–¶ How to fix
Verify DTCs in IBU.
What you'll see
Pack contactors are opened for protection.
System reaction
Slow emergency request to open pack contactors.
Diagnostic depth
Detection
The current measurments from the shunt sensor (primary) and hall-sensor are outside the tolerance value.
Possible cause
Sensor failure. Electromagnetic interference near hall sensor (secondary pack current sensor), e.g. large power/current source.
