Withdrawal
Remove the wire «masses» with battery.
Attention
- When the battery terminals are disconnected, the data on the recorded malfunctions are erased in the memory blocks of the control devices, therefore, before disconnecting the battery terminals, it is advisable to contact a specialized workshop to recall the malfunctions recorded in it from the memory. After connecting the battery terminal, it is necessary to activate and reprogram the power windows, as well as the position of the rear-view mirrors and seats.
- Also, if a radio with a code is installed in the car, then before disconnecting the terminals from the battery, check that you have the code to reactivate the receiver. Otherwise, it will be possible to put the radio receiver into operation only at a specialized station.
