Downloading Software

Downloading software

When software is to be downloaded to the vehicle there are a number of stages in the downloading procedure in VIDA:
- Preparations
- Verification
- Downloading
- Diagnostic services
- Confirmation
- Completion

Preparations
The preparations involve, among others that the user shall ascertain that the communications tool is connected and that there is sufficient power supply to the vehicle. VIDA performs a check of the voltage level status and the ignition position.

Verification
During verification, VIDA compares the software, hardware and serial number in the vehicle with that supplied in the software package.
If verification is OK, VIDA continues with the download.
If verification is not OK, a mismatch adaptation will be made and the Volvo central database will be updated before downloading can be performed.

Downloading
All control modules are set to programming mode when software is to be downloaded to a control module. Any existing software in the control module is erased so this cannot affect the new software.
When erasure is complete the new software is downloaded. Once the download has been sent a reset command is sent to the vehicle.

Diagnostic services
After the software has been downloaded, diagnostic services are run if necessary, for example, programming of codes or initialization of windows.

Confirmation
Confirmation involves a confirmation file containing the vehicle's new configuration being created and sent to the Volvo central database. This is to update the Volvo central database with the vehicle's latest status and so a mismatch adaptation is not performed with the next download.

Completion
The software download is completed by erasing all diagnostic trouble codes (DTC) stored in the vehicle.

Note! The clock in the vehicle may stop while downloading some software. Check the clock in the vehicle after downloading and adjust if necessary.
