Notes on no-load current consumption - AH54.10-P-0003-01TX

WARNING: This page does not describe the selected car, but rather 203 other vehicles, including the 2020 Mercedes-Benz SLC300, 2020 Mercedes-Benz SL550, 2020 Mercedes-Benz SL450, 2020 Mercedes-Benz S65 AMG, and 2020 Mercedes-Benz GLA250. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT The following parameters are to be observed:

Measurement value < 40 mA: 

This is the value that should be reached after 30 minutes at the latest.

Measurement value 1.2 A to 2.5 A: 

No bus idle; one control unit keeps the entire Class B (interior)

Controller Area Network bus (CAN-B) "awake".

Measurement value 80 mA to 180 mA: 

One control unit is not shutting down and this leads to an increased no-load current.

Another electrical or electronic component, e.g. a switch, could also cause increased no-load current consumption.
