Does TOPIx Diagnostics and the DDA need additional hardware?

No – TOPIx Cloud Diagnostics hosts the core software and does not require excessive hard disk space. The latest VCI is supported by the DDA.

Will there be future demands from Jaguar Land Rover (JLR) to retailers for new machines to be purchased as a minimum standard?

The vision is for TOPIX Cloud Diagnostics and the DDA to be compatible with certain machines.

What internet browsers are required?

For the best possible experience JLR recommend using the Google Chrome browser. Other internet browsers are supported.

Is there an offline capability?

No – TOPIx and the DDA require an internet connection at all times to allow authentication, latest information and functionality to be available to the user.

How does a user extract vehicle diagnostic session data?

This is done automatically when the session is active and on closure of a session. Data is passed from the your machine to the TOPIx system. Session data can be reviewed within TOPIx by you and a JLR Engineer.
