General Instructions / Safety Measures
• Never disconnect or connect wiring harness plugs from/to a control unit or an other electronic component with ignition switched on. • Never disconnect the battery from the vehicle electrical system while the engine is running. • Never start the engine without the battery properly connected. • Before charging or quick-charging, disconnect the battery from the vehicle electrical system. • Never use the battery quick-charger for starting. • Before welding on the vehicle, disconnect battery and remove control units. • With temperatures greater than 80 ° C (176 ° F) (i.e. paint oven) remove control units. • Use only high-resistance voltage testers for checking. • For test steps in which connection contacts of wiring harness plugs or control units are to be connected to ground or battery voltage (+12V), proceed with utmost care and concentration. An incorrectly selected contact can lead to destruction of internal circuits in the control units in question. • After reconnecting the battery, volatile memories must be reprogrammed. With radio coding and station programming, inform the customer about the decoding and deleted station memories. • If the engine or the automatic transmission have been removed, ensure that all ground connections have correctly connected after installation. If the engine is started despite a loose ground connection, this can cause damage to or destruction of the control unit.
