Adaption

A number of functions can be adapted via the channels:

  • ◆ Changes to tyre size
  • ◆ Changes of number of pulses from ABS wheel sensors
  • ◆ Activate/deactivate Service mode

The Service mode must be activated before the vehicle battery is disconnected and deactivated after the battery has been reconnected.

If the Service mode is active, the control unit does not switch over to emergency battery operation. No load is placed on the emergency battery in the control unit.

  • ◆ GSM aerial test selection

It is possible to determine which GSM aerial is to be monitored by the control unit. At present only the emergency aerial can be tested.

  • ◆ GSM aerial selection

For test purposes, it is possible to switch over to the main aerial or emergency aerial and to use a telephone connection to check that the aerials are functioning correctly. Under normal operating conditions, selection must be performed automatically.

The telematics system uses the pulses from the ABS sensors to calculate distance.

The individual functions are called up by way of the appropriate adaption channel number (refer to adaption table => Page01-262).

Activating/deactivating Service mode

The control unit switches over to emergency battery operation immediately when the vehicle battery is disconnected. If emergency battery operation remains active over a long period, the emergency battery will discharge and must then be replaced (fault code: 01531).

If the Service mode is active, the control unit does not switch over to emergency battery operation. The Service mode must be deactivated when service work has been completed.

Service mode can also be activated and deactivated by entering *#4610# on the handset.
