I learned about a "test mode" for the display, which can be used for diagnostics, without an obd reader.
I managed to get inside the test mode, but I am baffled by the data and am not sure what it means.
Visually it looks like this:
The line where it says "Part No BR51C" can be changed by pressing a button.
The particular part in question seems to be a spark plug. But what is this trying to tell me? Why is a random part number written?
Other lines contain the following information:
- dtcs none (I guess no error codes?)
- EE 01
- NROM 0117
- ROM 0117
- A14 00
- WI Code CD
- Port P -00
- and so on
Most of these things, except the part number, I can not find on google. What would you expect these lines to mean and why would a random part number be listed?
I checked some YouTube videos where other parts are displayed. Is it trying to tell me, that my spark plugs are gone (which I suspect anyway)?
