Diagnostics

Q: When trying to connect MultiAid to a vehicle I get the error "Unrecognised System Detected - Diagnostic tool requires an update".

      Does MultiAid need updating?

A: There are 3 possible reasons:

  1. MultiAid does not need to be updated. It is the software in the CAMU that needs updating

  2. MultiAid software needs updating

  3. You might get this error when trying to connect MultiAid to a vehicle that is from a different manufacturer

 

Q: I cannot connect MultiAid to the vehicle, why? 

A: Possible reasons are:

  • The wrong cable has been used

  • The driver might be corrupted

  • The wrong USB port has been used (on some laptops, it is required to use only specific USB port)

 

Q: Can I use MultiDiag VCI on MultiAid?

A: MultiDiag VCI does not work on MultiAid, MultiMux and Cummins


Cummins License

Q: How do I get my Cummins license?

A: It depends on who you have purchased it from:

  • If you have purchased it from Actia, you need to complete the Cummins registration form and fax or email it to Actia, who will then apply for the license with Cummins and it will get emailed to the engineering manager for your depot

  • If you have purchased it from Cummins, you need to contact Cummins direct
