Vehicle communication

To be able to perform diagnostic read-out, diagnostic fault tracing and software download, the vehicle needs to be connected via vehicle communication equipment to the VIDA workstation. The communication equipment will transfer messages between the workstation and the correct receivers in the vehicle. Please note that this equipment is not included in the VIDA subscription, it has to be purchased separately.

Vehicle communication for VDS protocol-based vehicles
VDS* protocol-based vehicles support vehicle communication by Ethernet cable. No vehicle communication tool such as DiCE is needed. There is still support for DiCE and J2534 devices but the communication may be very slow using these devices. The Ethernet cable is connected from the VIDA workstation's Ethernet network input into the vehicle's OBD-connector via a VOE (Volvo OBD to Ethernet) adapter. This adapter is a Volvo special tool with number 9513062.

Vehicle communication for D2/GGD protocol-based vehicles
For D2/GGD** protocol-based vehicles, Volvo Car Corporation recommends using the vehicle communication tool DiCE. A DiCE unit can be purchased from authorized Volvo dealers. DiCE transmits information between VIDA and the vehicle via Bluetooth or a USB cable. From time to time DiCE units may require updating with new software (also called firmware). The update is performed via VIDA. The DiCE unit must be connected to a 12 V power supply or a vehicle, and to the VIDA computer via a USB-cable.

Volvo Car Corporation does not test or certify other aftermarket communication tools. However, D2/GGD protocol-based Volvo vehicles are also compatible with other standardised J2534 devices.

For further information about vehicle communication, see VIDA Help (available in VIDA). For more information about required and recommended equipment, please refer to the document Workshop System Requirement and Guidelines.


* Diagnostic protocol used in all vehicles on the new electrical platform, starting with XC90 model year 2016.
** Diagnostic protocol used by vehicles on other existing platforms.
