Exposing And Removing Relay Box In Passenger Compartment: Notes
CAUTION:
The customer-programmed data must be read off before the control module is replaced. The information must then be entered into the new control module after it has been installed. This is performed via VIDA vehicle communication.
NOTE:
Applies to vehicles -2003, All ignition keys are needed when programming a new control module.
NOTE:
For vehicles equipped with Volvo On Call (see phone's keypad) the battery's minus lead shall be removed first. Otherwise the automatic alarm for emergency services may be triggered. See Battery, Disconnecting
NOTE:
The driver information module (DIM) must not be replaced at the same time. This would erase the mileage.
