Today, I received a 08-year-old Ford Focus, and the owner described that sometimes it can be started and sometimes it can't, and the anti-theft lights keep flashing when it can't be started.
This malfunction is a common problem, and Fox suffers from this kind of malfunction.
Because this car is instrument anti-theft, anti-theft data is stored in the instrument. If the instrument is virtually connected, the vehicle will not start.
The solution is actually very simple, remove the instrument and solder the pins behind the instrument plug to solve this fault.
Since we have talked about this model, let's talk about the anti-theft data analysis of this car and the method of handwriting start. If the key is lost or the instrument is replaced, the device cannot enter the anti-theft system, and the key cannot be matched, we can read the anti-theft data in the instrument, and then use the method of writing to start the car to start.
First of all, Fox's anti-theft system is integrated into the meter, and the anti-theft data is stored in the CPU of the meter, which needs to be read with a programmer wiring.
Read out the anti-theft data, but also know where the important anti-theft data is.
We are engaged in anti-theft, we must learn the analysis of data, know where the synchronization data, key key, key ID and password are, whether the data is encrypted, the anti-theft data of some models will be verified, and we have to crack its verification algorithm and so on. These can only be mastered through continuous learning and exploration.
Without further ado, here's how to analyze the data of the Ford Focus instrument anti-theft and write the start by hand.
