LIN error on all components.
Check the LIN cable harness. If one of the units on the LIN-bus is faulty it can affect the other units further down the same communication line. The LIN-units are split into three lines from C8061, one to the sun sensor, one to the humidity sensor via C24, and one to multiple units via C8046. From C8046 the units are arranged: air intake/recirc control motor, air dist/defrost. motor, mix air/temp flap motor, panel/floor flap dist. motor, 2nd recirc/AQS motor and AQS-sensor.
What you'll see
No driver-visible symptom recorded.
System reaction
The LIN actuators/sensors will not function.
Diagnostic depth
The climate control system (17) has detected a LIN communication error with the actuator. The test is performed continuously when the supply to the LIN nodes is active.
There may be an internal error in the actuators/sensors or an error in the cable harness.
