An automated strategy to deactivate lane assist

Recommended Posts

The lane assist and other "safety" capabilities are not possible to be permanently removed; they immediately activate with every restart.

If the devices can be manipulated over the CAN bus, it should be quite simple to create the appropriate CAN messages using a compact microcontroller such as the Teensy 4.1 and an interface chip like the MCP2515.

Once I get the opportunity, I plan to scan the canbus to observe the messages created when each feature is activated or deactivated. By doing so, I will be able to connect to the can bus and send a message after every vehicle restart to disable the functions that are bothersome to me. I intended to include DIP switches to enable the selection of desired features or deactivate them. A compact dongle box that is powered by the diagnostic connector would be appropriate.

Although it may be deemed unattainable, I am determined to attempt it.

In the United Kingdom (and likely across Europe), if you were involved in a collision and the insurance investigator discovered it, your insurance coverage would be invalidated.

Insurers often seek justifications to evade making a payment, and while it may be challenging to detect alterations made to maps and codes, discovering an unaccounted-for box connected to cables would undoubtedly raise suspicions.

Unfortunately, the Mazda Lane Assist system is very ineffective and has already resulted in accidents.

Currently, my CX60 vehicle is equipped with an XBB auxiliary light that is activated or deactivated using a dongle connected to the CAM bus connection. The approach you provide would need me to decide between this option and the lane assist disabler. Unless you use a dongle that is compatible with both the connection and this particular dongle.
However, I would much appreciate the solution you provide 🙂
