5. Transport Mode/Customer Mode of Car's Electrical System
5. Transport mode/customer mode of car's electrical systemBecause the car's electrical system requires current, there are two different adaptations - transport mode and customer mode.
Transport mode
Minimises the car's current consumption during transport from the factory to the customer. Many customer-oriented functions are then not available, such as central locking of rear doors, rear window lifts and the audio/navigation system. The car is to be removed from this mode only as an exception during the car's handling up until delivery service has been performed. An example of an exception is cars parked in a showroom. If the car is put in customer mode, battery condition must be checked more often.
Function description: Activate transport mode
The front electrical centre sends a signal on the I-bus that the fuse is removed. At the same time, a number of control modules in the rear electrical centre that are powered by this fuse are deactivated. Examples of deactivated functions include the parking assistance system, sunroof and rear door modules.
The Body Control Module (BCM) reads the signal, at which time BCM sends a message on the I-bus indicating that transport mode is activated. This affects the control modules containing customer functions/comfort functions that are not necessary to be able to safely move the car, which is not supplied current by maxi fuse 37 and the rear electrical centre. This operation only occurs during cycling of the ignition to enable distinction from the fuse blowing while driving, at which point other indications/warnings would be given to the driver.
Indication in MIU: "Transport fuse removed".
Activate transport mode
Move the transport fuse from position 37 to TRANSPORT and turn the ignition key to "Ignition ON". Wait until the text "Transport fuse removed" appears in the main instrument unit and then turn the key back to the OFF position and remove it. The car is now in transport mode.
Customer mode
All functions (as per car specification) are now available to the customer.
Note that only the combination of fitting/removing maxi fuse 37 and turning the ignition key to "Ignition ON" changes the mode. So starting and moving the car changes the selected mode if the fuse was removed/inserted (customer or transport mode).
Function description: Activate customer mode
The front electrical centre sends a signal on the I-bus indicating that the fuse is inserted.
The Body Control Module (BCM) reads this signal, at which time the BCM sends a message on the I-bus indicating that customer mode is activated. This only occurs during cycling of the ignition. Thus, the ignition must be switched on and off to activate customer functions (customer mode).
No indication in MIU. Only the "normal view" appears.
Activate customer mode
Move the transport fuse from TRANSPORT to position 37 and turn the ignition key to "Ignition ON". Wait until the text "system check" in the main instrument unit shows "OK" and then turn the key back to the OFF position and remove it. The car is now in customer mode.
Demo/showroom cars
Trickle charging is recommended to prevent battery discharge and damage. The amount of charging should be adapted to current consumption. Too high voltage/current from the charger could damage the battery due to overcharging.
If trickle charging is not possible, the battery must be checked often (depending on current consumption) - a minimum of once a week. Use the standard battery analyser to check battery status.
