Question
How to test faulty automotive LIN bus master node in body control systems?
Answer
Monitor LIN bus communication and test master node signal output.
Explain
A faulty LIN bus master node disables body control functions (e.g., door locks, wipers). CHEPQ tools monitor LIN bus traffic (9600 baud) and test master node signal output—replacing the master node restores body system functionality.
