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

Problem

The message appears in the Omni:

E 210102 & E 210109 - 'The battery cannot be reused and must be returned 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 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)...
