Because the temperature sensor wire runs from the exterior mirror through the door shell and into the cabin, it passes through a flexible rubber boot at the door hinge. Moisture ingress inside this multi-pin connector can rust the terminals, fracturing the data path. 3. CAN Bus Network Interference Modern Renault vehicles rely heavily on a multiplex
