61 35... Notes on ESD protection (Electro Static Discharge)

WARNING: This page is about a different car, the 2011 BMW X6 and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required:

12 7 060

NOTE: Electrical components which are particularly sensitive to electrostatic discharge (electronic control units, sensors, etc.) are marked with the ESD warning symbol.
E -Electro
S -Static
D -Discharge

Statically charged persons can discharge themselves when they touch electrical components.

NOTE: Humans can only detect a discharge starting from a level of approx. 3000 V.
The danger threshold for electrical components already starts from a level of approx. 100 V.

IMPORTANT: Do not touch pins and multi-pin connectors directly!
Touch electrical components by their housings only.

IMPORTANT: To avoid damaging or destroying electrical components as a result of electrostatic discharge, it is absolutely essential to observe the following instructions:

When replacing electrical components, leave the replacement components in their original packaging until immediately before they are to be installed
If necessary, always return a removed component in its original packaging (always pack the component away immediately)
Read and comply with user information on using the associated special tool 12 7 060

Personal protective equipment:

Electrically conducting clothing (high wool content, antistatic shoes required).

These can primarily be identified by the logo on the side.
