Canbus and problems using an bluetooth OBD2 scanner.

This is the sticker on the ECU.

Benjamin Which scanner, with photos?

Benjamin

This is the OBD2 Scanner.

Benjamin

The issue with the OBD2 scanner only happens when Im using DUDU OS to connect. If I use Torque, or CarScanner, there are no issues whatsoever.

I can also mention that I think the head unit is connected to the canbus, because when I put the car in reverse, it does detect the reverse, and changes screen. The reverse camera are only connected to the head unit, not to the reverse light.

Benjamin

Small update. After taking pics of the scanner, I plugged it in and took the car for a drive, and now it worked. No problems with flashing warning lights.

But one question I have is, what info can I expect to get from the scanner? The original HU would show both instant and average fuel consumption. All Im getting from DUDU are battery woltage and coolant temperature. It does not show outside and inside temperature.

What about the canbus then? Are the DUDU7 compatible with the ECU in my car?

Usually they ask about the car you have when you order and send you the canbus box with the HU. You didn't get one?

Benjamin

Teklock Just the head unit and cables for connecting to the canbus, wich should be enough i guess. Just not sure if my car is supported.

You probably need to reach out to whoever sold you the HU and get your canbus box. You likely won't be able to do what you want via canbus with an OBDII scanner.
