With the CanBus Multiplex Trainer, you can read the hexadecimal data used by your modules to communicate. You can also inject fake data to simulate a fault without compromising your vehicle's integrity, allowing you to learn about the CanBus communication network in depth. Here's how:
1. Generate a real fault by disconnecting a sensor from your car.
2. Identify which PID changed when the fault was generated and what data accompanies it.
3. Identify the bytes where the information changes, causing the fault.
4. In the software's interval section, write the data that caused the fault and send it, along with the associated fault code.
Now connect your scanner. You will see both the fault and the live data associated with it. This will give you a thorough understanding of how faults are generated, what data changes, and how the vehicle behaves when they occur.
Note: As an extra piece of information, this is the question-and-answer data pattern that a MAF sensor gives when it malfunctions:
Question:
0x7E0 0x03 0x22 0x12 0x09 0xFF 0xFF 0xFF 0xFF
Answer:
0x7E8 0x05 0x62 0x12 0x09 0x00 0x95 0x00 0x00
