U100587 — Low-speed warning lost communication
Quick answer
U100587 indicates that the gateway has lost communication with the low-speed warning unit, so the car will not warn pedestrians when it is moving slowly.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- Check whether other modules on the same network also report communication faults; one module offline can set codes in several others.
- Check the 12 V battery state of charge and terminals; a weak 12 V supply causes many electronic faults.
Symptoms you may notice
- No low-speed warning sound
- Pedestrian warning fault
- U100587 stored in the gateway
- Warning sound cutting out
Can I still drive?
Usually drivable — have it checked soon. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
