Problem
The message appears in the Omni:
E 210102 & E 210109 – „The battery can no longer be used and must be handed over to the dealer for inspection.“.
For safety reasons, the battery is permanently deactivated and the vehicle is no longer ready to drive.
Cause
The cause is usually a short circuit in the 48 V vehicle electrical system. Possible sources are
- Lighting Supernova m99 Pro (ST2S / ST5)
- Lighting Roxim ZE4
- the Cabling...
- The motor controller (MCU) > see below
- Distribution Board
- cabling, here specifically the wicket cable). The wicket cable connects the battery compartment to the motor controller (MCU).
Solution
The battery must be sent to Stromer for inspection/reset.
The cause of the protective tripping must be rectified before a battery is reinserted.
Stromer writes:
With the firmware SUI FW 4.2.2.1 New protective measures were introduced on December 5, 2019, which permanently deactivate the battery in the event of a short circuit at the 48 V output. If the battery is deactivated, the following error messages will appear on the OMNI: E 210102 & E 210109 and the text: „The battery can no longer be used and must be returned to the dealer for inspection.“.
A second averaging states:
If the OMNI displays the error messages E 210102 & E 210109, it is very likely that this is caused by a faulty controller. Before the battery can be replaced, the controller must be checked for specific discolorations (burn marks) on the circuit board (ceramic capacitors)...
