Indigo - Diagnostic Tester

Indigo is an easy to use and intuitive diagnostic tester for all diagnostic tasks and can be used in vehicle development as well as in the workshop. Thanks to its modular design, Indigo can be individually adapted to customer needs and company processes.

Indigo gives you a quick overview of the status of a vehicle as well as detailed diagnostic information on individual ECUs. Depending on your needs, you define a suitable tester configuration, save it as a project and share it with your colleagues. Furthermore, with Indigo's unique selling point, remote diagnostics, you can easily diagnose vehicles and ECUs remotely.



  • Use case oriented tool approach
  • Simple operation, decoupled from diagnostic services
  • Use Case Windows definable for each project, selectable from a ready-to-use diagnostic toolbox
  • Automatic configuration of diagnostic parameters using ODX, CANdelaStudio (CDD) or Ford MDX diagnostic descriptions


  • Vehicle diagnostics and commercial vehicle diagnostics with many ECUs simultaneously, as well as diagnostics of individual ECUs in the vehicle or in a lab environment
  • Perfectly suited for OEMs and suppliers
  • Interactive remote diagnostics with Indigo Option Remote


  • Can be integrated into existing development processes at OEMs and suppliers
  • Development of customized diagnostic windows in C# with the Indigo Software Development Kit (Indigo SDK)
  • Integrated environment for recording, editing and replaying diagnostic sequences/scripts using the Vector Diagnostic Scripting (VDS) library in C#


  • Simultaneous communication over different bus systems: CAN (FD), K-Line and DoIP as well as different diagnostic protocols: UDS, KWP2000, GMW3110, SAE J1939 diagnostics, OBD, WWH-OBD, HD-OBD and OBDonUDS
  • Bus logging and (graphical) measurement of network signals from DBC/ARXML

Application Areas


Indigo is the perfect diagnostic tester in ECU and vehicle development. Indigo is used starting with the setup of ECUs in a laboratory environment, through vehicle roll-out and modification in test workshops, to vehicle test drives.

The user interface can be freely configured using predefined tools from a toolbox for different diagnostic tasks. The resulting user interface is saved together with the diagnostic description files as a project or as Pack&Go. The use of "protected projects" makes Indigo particularly suitable for collaboration with development partners and workshops. The extraction of sensitive diagnostic data (databases and private keys) is prevented by protected projects. In addition, protected projects can be provided with passwords and expiration dates.

For use on test drives, Indigo is operated quickly and specifically via keys. The measurement of data or readout of fault memories can be triggered in this way, and acquired data can be temporarily stored for later analysis. For documentation purposes, the user generates reports in a clear and customizable form with Indigo.

Indigo Remote

Indigo Remote saves the user time and money when remotely diagnosing vehicles and ECUs. The advantage of Indigo Remote is that all confidential data remains with the Indigo user and is not transferred to a remote location.

The areas of application in general are e.g.:

  • Remote diagnostics of integration components
  • Vehicles on test drives
  • Vehicles in foreign production plants
  • Customer vehicles in the workshop

Remote diagnostics is activated in Indigo using a special Indigo Remote license. A connection to a remote access point is then established. The Remote Access Point can be downloaded free of charge from the Vector homepage at this link.

Remote Diagnostics & Flashing - Enormous Time Savings at Webasto

The demand for Webasto battery systems is growing steadily. The Field Application Engineers (FAE) are faced with the challenge of meeting a support demand that is growing by 50-100% annually. This cannot be easily compensated for by expanding the FAE team in terms of personnel. 

Enormous time savings with Vector´s remote diagnostic tools Indigo and vFlash: Without remote diagnostic tools, about 90% of the customer meetings took place on-site. Today the ratio is reversed, about 85% of the meetings take place remotely. As a result, instead of 1-2 customer issues per week, up to 10 customer issues are now processed per FAE.

Indigo - Interactive Remote Diagnostics

With Indigo Remote starting version 4.0 and higher, Indigo supports interactive remote diagnostics. An expert on a PC conducts a remote diagnostic session with a special ID or password. Communication takes place via a secure Vector Remote Server. On the vehicle side it is sufficient to start the access point and forward the access data to the expert. No changes to the vehicle are necessary and the software for the access point can be downloaded here free of charge according to your contact details. This means that Indigo is immediately ready for use in case of need.

As an alternative to the PC and network interface for vehicle access, the Intelligent Diagnostic Device VN8810 is also available. The compact device from Vector has an integrated interface (CAN(FD), K-Line, Ethernet) and can easily be equipped with the Indigo Access Point Compact via the Vector Platform Manager.

The Indigo Access Point software (PC) and Indigo Access Point Compact (VN8810) required for local access to the vehicle are part of the Indigo delivery. Both can be quickly installed without admin rights.

With Indigo Remote, diagnostic data, test sequences and security algorithms remain in a secure environment - all control, interpretation and evaluation takes place on the expert computer. Together with end-to-end encryption via the Indigo Remote Server, high data security is guaranteed.

A number of technical measures ensure high bandwidth and low latency so that the full scope of diagnostics can be used efficiently. This makes it possible to access vehicles worldwide with very short response times - even when transferring large amounts of data.

Indigo Remote can be used anywhere whenever an expert needs direct access to a distant vehicle or ECU for remote diagnostics.

General areas of application include:

  • Remote diagnostics of integration components: When starting up integration components, Indigo Remote enables developers to help remotely at short notice in the event of problems. Development partners can immediately identify the problem using remote diagnostics and take the appropriate action.
  • Vehicles on test runs: During a test drive, a vehicle exhibits unusual behavior only under very specific conditions. A precise examination by an expert or system developer is needed. In very few cases, this expert is on site and can use vehicle diagnostics to read out important vehicle data and control actuators for testing purposes. With Indigo Remote, the expert can now access the vehicle directly, despite being very far from the site.
  • Vehicles in offshore production plants: Indigo Remote offers short-term support from remote developers for problems with the vehicle, system or ECU. Thus, both OEMs and suppliers can use remote diagnostics to diagnose their systems quickly and securely during start-up phase in a production plant.
  • Customer vehicles in the service shop: At service shops, there are sometimes situations that require consultation with an expert. For those, Indigo Remote offers prompt help from “vehicle doctors” or developers from the headquarters if an unexpectedly complex problem arises. This makes it possible to provide customers fast and cost-efficient repairs.
