Bosch drive unit error codes list

Published on 10/31/2019

Excerpt from the original Bosch

Displays and settings on the control computer are only possible if the electric bike battery is on. The control computer itself does not have an electrical power supply.

The Light showing the state of battery charge

In addition to the light on the battery, it is also possible to read the charge status on the f light of the control computer.
On the light, each bar in the battery symbol corresponds to about 20% capacity.
At less than 5% capacity, training assistance is no longer possible.
The LEDs of the light indicating the state of charge of the battery are extinguished.
If the electric bike is powered by battery (depending on the versions of the different countries), the capacity will be sufficient for about 2 hours of lighting after the first
the empty battery symbol.
When the symbol starts to flash, lighting is only possible for a short time.

The elements of the electric bike drive are automatically checked at all times. If an error is detected, the corresponding error code will appear on the e view. Depending on the type of error, the training is eventually automatically stopped. However, it is always possible to continue riding without being assisted by training. It is recommended that the electric bike be checked before other routes.

200Internal battery electronic errorHave the battery checked
201Battery temperature too high (above 40 degrees Celsius)Allow the battery to cool. The continuation of the race without electric bike drive is possible and speeds up the cooling of the battery.
202Battery temperature too low (less than 10 degrees Fahrenheit)Allow the battery to heat up slowly in a warm place.
203Battery connection problemHave connections and connections checked
