Bosch eBike 152002: The temperature of your control unit is too high.

Risk level
High
Professional inspection is recommended.
Urgency
Immediate
Quick answer
The temperature of your control unit is too high. This may significantly reduce the LED brightness of the control unit. For 152002, Bosch's user step is: Let your eBike cool down for ten minutes in a cooler environment. Avoid direct sunlight here. If the same code returns, preserve the display and stop repeating resets.
Safety first
Stop and check this first
- Stop riding or charging while a battery, drive unit, cable or connector is abnormally hot. Keep it away from combustible material; smoke, swelling, hissing or burning smell requires emergency help.
Safe checks you can perform
- Preserve the code before changing anything
- Apply only Bosch's published user step
- Use recurrence as the stop point

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

Evidence: Bosch eBike Systems — official fault code 152002
- What the official step decidesPossible
