Repair of Smart ForFour w453 2019 BMS module for HVB

Smart ForFour BMS N82 / 2 (Electronic Battery Management System)

BMS for high voltage electric car.

Typical Problems

P0DE71C - The cell voltaes of the hybrid/high-voltage battery module are too high. The voltage value is outside the permissible range.

P0DE616 - EMF of galvanic cells of the high-voltage battery module is too low. The voltage value has dropped below the voltage limit value.

P0B3B13 Hybrid / EV Battery Voltage Sense “A” Circuit - circuit open

P0B3B62 - Hybrid / EV Battery Voltage Sense “A” Circuit - signal compare failure

P0DE61C - EMF of galvanic cells of the high-voltage battery module is too low. The voltage value is out of range.

P0DE663 - EMF of galvanic cells of the high-voltage battery module is too low. Activation time exceeded: overload protection active.

P0DE697 - EMF of galvanic cells of the high-voltage battery module is too low. System functions are limited.

P0DE763 - EMF of galvanic cells of the high-voltage battery module is too high. Activation time exceeded: overload protection active.

P1D2771 - The frequency counter for the "Contactor switching cycles" of the HV battery module will soon reach its end position. The actuator is locked.

P1D2777 - The frequency counter for the "Contactor switching cycles" of the HV battery module will soon reach its end position. The prescribed position is unattainable.

P1D2785 - The frequency counter for the "Contactor switching cycles" of the HV battery module will soon reach its end position. A signal is present above the permissible limit value.

P1D2877 - The HV battery module "Contactor changeover cycles" frequency counter has reached its final value. The prescribed position is unattainable.

P1D2885 - The HV battery module "contactor switching cycles" frequency counter has reached its final value. A signal is present above the permissible limit value.
