Rules for working with electrical equipment components
Switch off the ignition before disconnecting or connecting electrical components. This will eliminate the possibility of damage to electronic equipment from power surges at the time of disconnecting live components.
The workplace and hands must be clean from oil, chips and other contaminants. Oil attracts dirt particles that can cause electrical leakage (short circuit) or increasing circuit resistance.
When handling printed circuit boards, be careful, handle them only by the edges. Remember that some electronic components are afraid of static electricity.
Never use excessive force to connect or disconnect connectors; this requirement applies in particular to printed circuit board connectors. Damaged contacts can cause short circuits or open circuits.
Before starting work and periodically during diagnosis, touch with your hand "masses" vehicle to drain static electricity. Some components of electronic equipment can be damaged by static electricity on the body or clothing.
Lubrication of electrical components
Some electrical connectors located under the bottom of the body or under the hood are protected against corrosion during production with a special grease. If the integrity of such connectors has been violated or the connectors are to be replaced, then they must be treated with a special lubricant: Lubricant catalog number BAU 5811, supplied in tubes of 150 grams.
NOTE: Do not use grease other than BAU 5811. Doing so may cause the grease to come into contact with relay and switch contacts and cause intermittent contact loss or failure to function.
