3.3.8 Malfunction Indication
The Display DDU 18 is capable to indicate critical faults of the BOSCH MOTORSPORT e-
GoKart System to the driver via a dedicated malfunction indication lamp (MIL) implemen-
ted as telltale in the Display DDU 18, see blue marked lamp in the following figure.

Malfunction Indication Lamp
Additionally some internal faults of the BOSCH MOTORSPORT e-GoKart System, e.g. faults
in the torque path, will lead to very limited operation with a minimum allowable speed of
5 km/h and low torque. This state is called limp-home operation and enables the driver to
bring the vehicle into a safe parking position.
3.3.9 Software Updates (Flashing)
Updating the BOSCH MOTORSPORT e-GoKart System software (flashing) is possible for all
system components via one single system interface with a defined tester-interface infra-
structure.
Software updates will be provided by BOSCH MOTORSPORT if necessary.
# It is not allowed to update the software of the BOSCH MOTORSPORT e-GoKart System
by the CUSTOMER or any other third party without explicit authorization by BOSCH MO-
TORSPORT.
3.3.10 Deep Discharge Protection
Operation of the BOSCH MOTORSPORT e-GoKart System is only possible if the Energy
Storages ES 5-2.4 are charged frequently. Under normal conditions a software functional-
ity of the BOSCH MOTORSPORT e-GoKart System operates all Energy Storages ES 5-2.4 in
valid operational limits so that no Energy Storage ES 5-2.4 will run in deep discharge state.
Once this limit is violated and an Energy Storage ES 5-2.4 is deep discharged, operation of
the Energy Storage ES 5-2.4 will be prevented by the BOSCH MOTORSPORT e-GoKart Sys-
tem.
3.3.11 Shut Down
Regular shut down of the system is initiated by terminal 15 switch-off or critical low 12 V
battery voltage.
