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.
Software Downloading
The control modules used as slave nodes on Volvo's LIN buses are supplied preconfigured and with that programmed for a specific behavior.
Volvo does not use software downloading via LIN. However a new configuration file for a LIN bus can be downloaded to the master node that controls communication on a LIN bus, on condition that the master mode is connected to the vehicle's CAN network.
Accordingly, new slave nodes can be added to an existing LIN bus.
