While working on a new project, I needed an additional switch to control my device. The MX-5 2016 ST has a place holder for the switch, which in the RF model is used to control the roof closing/opening. I decided to use this place holder to add my own switch. On the Miata forum there was some discussion about the possibility of adding new switches, but no real implementation yet. Continue reading
After getting familiar with CAN bus usage in my MX-5, I decided to build a universal module, based on $10 Raspberry Pi Zero W microcomputer.
Thingiverse While I was working with CAN scanning, I accidentally drained my car battery to the point where I could not crank the engine. I decided to do a little research on battery capacity. Continue reading
While working on my projects, I did several attempts to depict Mazda CAN protocol, to find useful information. For example, getting the shift position for the “smart “mirror project and the fuel level for the fuel reminder. There are many products available for the OBD2 protocol. One good product is TouchScan with Mazda extension, which allows you to access every module in the car for diagnostic purposes. Using this tool, I figured out how to get access to the fuel gauge on the console, instead of using the sensor in the tank. However, while it is a very useful tool, it does not provide access to real-time information available on CAN bus as broadcasted messages. Continue reading
Mazda MX-5 2016 GT has advanced safety features, like Lane Departure Warning System (LDWS ) and adaptive High Beam Control (HBC).
Here is the Mazda document, showing how it works. This is the manual for Mazda 6, but MX-5 is identical.
I’m not sure about the value of having LDWS on a sport car, like MX-5. It often produces false alerts which is quite annoying. Disabling this feature by turning it off will show up as a yellow warning light, which is also annoying. I’ve not had a chance to test the HBC feature yet. So, I was thinking to turn this camera into a dash cam, by hacking it or even replacing the whole PCB. Continue reading
