E 210102 & E 210109 | Battery deactivated, not ready to drive

Problem

The message appears in the Omni:

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 checking/resetting. The cause of the protective tripping must be rectified before a new battery is inserted.

Stromer writes:

With the firmware SUI FW 4.2.2.1 vm 5-12-2019, new protective measures have been incorporated which permanently deactivate the battery in the event of a short circuit at the 48 V output. If the battery is deactivated, the error messages 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)...
