DTC › MGU2 MGU2 / 0C00

Very High DC-Bus Voltage

â–¶ How to fix

Bad connection between MGU and propulsion battery, check connections

What you'll see

No propulsion from MGS available. May also set fault codes of short circuit-

System reaction

Short-circuit of electric motor by inverter. Yellow OBD

Diagnostic depth

Detection

Evaluation Condition Always. Set Condition A first-order low pass filter is used (same as for FilteredVoltage) for voltage. DC bus voltage is above high level. Clear Condition A first-order low pass filter is used (same as for FilteredVoltage) for voltage. DC bus voltage is below high level.

Possible cause

Using braking torque with with no battery or bleeder connected to DC bus Braking power exceeds battery's limits (e.g. cold battery) External power source on DC bus raises the voltage Bad current control settings Internal sensor failure
