Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Terminating resistor
A = Master node
B = Slave node
C = Transmitter/receiver
LIN is terminated to the battery voltage on each node via a pull-up resistance
The master node is terminated with 1 kΞ© and the slave nodes with 30 kΞ©.
The termination resistance forms a parallel circuit and the resistance to the battery voltage depends on the number of connected nodes. The resistance to ground should be infinite or at least extremely large if no communications are in progress.
