Current Limiting

The central electronic module (CEM) checks and sometimes limits the current from the battery and generator. The central electronic module (CEM) can prioritize between different loads in the prevailing conditions.

If there is a fault with current limitation, the general warning lamp will light in the driver information module (DIM) and a text message will be displayed.
