Mercedes-Benz A220 2020 Technical Service Bulletin # S-54_00-238 Date: 110323


Electrical - Electrostatic Discharge Damage Prevention



Date: March 23, 2011



Order No: S-B-54.00/238



Group: 54



SUBJECT: MY-All, All Models



Preventing Damage to Electronic Components Due to Electrostatic Discharge



Warning!



Every contact and each physical separation of material or any movement of solid substance, fluids or particulate loaded gases can generate



electrostatic charges. Plastic generally produces the highest electrostatic charge.



The following electronic components listed as an example can be damaged by ESD:



- Airbag components



- Control units, in particular their bus connections: Control Area Network (data bus/CAN bus) (CAN), local interconnect network (LIN), etc.



- Sensors



- Antenna amplifier



- Receivers and displays (Radio, TV, GPS, telephone, etc.)



- Multifunction antenna assembly



Safety precautions:



- Avoidance of contact with electrostatic chargeable materials such as PE, PVC, Styrofoam.



- Use only original packaging or specially labeled and defined packaging and transport materials.



- Electronic components which have been removed must be put down on an ESD workplace. (Example: when swapping the painted cover from one



multifunction antenna to another, this must be performed on an ESD table mat (000 589 52 98 000).



- Touch connectors on electronic components and wiring harness on the housing only. Do not touch the pins and contacts!



- Electronic components must be installed before they are connected so that potential equalization with the body can take place.



Returning electronic components in warranty and goodwill cases:



When returning electronic components it is absolutely essential to observe the procedure and safety precautions listed in WIS doc.



AH54.00-P-0001-01A. Electrostatic charge or discharge means the original fault can be falsified or overlaid. This can lead to distorted faults



symptoms in the case of the fault analysis of the component concerned.
