Downloading Software And Replacing The Control Module

New software can be downloaded into the driver information module (DIM). When ordering software, the hardware and the software in the car is compared to the information in the Volvo central database. If the comparison is OK the software is downloaded to the control module.

If the comparison between the car and the Volvo central database does not correspond, the database is updated with the configuration of the car. The software download then begins.

The control module is integrated in the driver information module (DIM). When replacing the control module the entire combined instrument panel must also be replaced.

The language in the combined instrument panel can be changed. This is done by ordering new software for the driver information module (DIM) from the replacement parts catalogue. In the replacement parts catalogue there is software for reloading the driver information module (DIM) (Reloading DIM) and software for changing to a number of different languages. Reloading reloads the same software that was installed before the control module was replaced.

There are other functions in the combined control module which can be ordered. However, these are not downloaded into the driver information module (DIM) but into the central electronic module (CEM). These are functions such as the trip computer.

A number of customer parameters can be programmed into the driver information module (DIM). This is not done using software downloads but using VIDA vehicle communication.

To change the customer parameters that affect the conditions for the message being displayed, the vehicle configuration file must be updated so that the market code for the driver information module (DIM) is reset to User Defined. This update is made through a software download. This only needs to be done once.

The following customer parameters can be programmed into the driver information module (DIM):

• Conditions for the service message to be displayed, mileage, time and engine hours.
• Unit of temperature. The options are Fahrenheit and Celsius. No software download is required.
• Units in the trip computer (only applies to vehicles with trip computers). Fuel consumption can be displayed in liters per 100 km, miles per GB Gallon, miles per US Gallon and kilometers per liter No software download is required.
• 12 or 24 hour clock display. No software download is required.

These customer parameters are stored in the driver information module (DIM) but not in the Volvo central database. This means that the customer parameters must be reprogrammed when hardware is replaced.
