When a vehicle’s modules are replaced with new or used parts they often require recalibration.
This special function allows adjusting of the mileage stored in the BSI device and the dashboard. Since the BSI is synchronized with the vehicle dashboard, the operation have to be performed on both BSI and dashboard or only to the BSI but with an option to disable dashboard synchronization selected. Up to now only the dashboards for the Peugeot 308 and Peugeot 407 with Siemens BSI have to be removed and adjusted manually with an EEPROM programmer by dump. You can set them to 0 km because once they are connected to the BSI they will get the correct mileage from it.
After Calibration is opened, select the vehicle and the unit. If you’re not sure which is the car model or unit, you can leave it to “< AUTO DETECT >” and “< AUTO DETECT >”. Click “Connect” to get odometer.
There are two options available
-
Disable dashboard synchronisation removes the synchronization between the dashboard and the BSI so only the BSI can be adjusted while the dashboard shows only BSI mileage independent of its own value.
-
Write dashboard – dashboard mileage is updated together with the BSI. Note that this option is available only for a few vehicles (Citroen C2, C5 II, C4 II, DS4, DS5, Peugeot 508) and it requires Vehicle model to be manually preselected!
This procedure like ReadSecurityCode procedure can take up to 15 minutes (45 minutes for C5 II dashboard), and in case of any interruption it can leave the car into service mode. That’s why it has to be resumed as soon as possible to get the car into operational state.
You can protect vehicle battery by removing the wipers and low beam fuse as described in ReadSecurityCode procedure.
At the end of the procedure the following message appears. Note that it really important to switch OFF ignition and leave the cat intact for a few minutes for the new odometer to be really accepted by the car. After operation completed successfully you can click “Connect” button again to verify that the odometer is modified correctly.
