Think of it as the master switch panel for how the ECU talks to the outside world. You'll use it when you first set up the ECU, when you add a CAN device like a dash or keypad, and when something that should be talking to the ECU has gone quiet.
Three things to check here:
- Is the link enabled? A CAN bus or Wi-Fi that's switched off here won't work, however well the rest is set up.
- Anything in red? NSP highlights errors in red. Fix those before you go hunting in the wiring.
- Wi-Fi settings: click the Wi-Fi name to jump straight to its settings page.
For the detail behind each link, see Haltech CAN system, vehicle CAN system and Wi-Fi. Need a screenshot of this page? Ask us and we'll send it over with advice for your build.
