LIN error on all components.
â–¶ How to fix
Check the LIN cable harness.
What you'll see
The climate control system will not be able to control flap actuators or fans in the rear climate systems
System reaction
The LIN actuators will not function.
Diagnostic depth
Detection
The climate control system (E138) has detected a LIN communication error with the actuators. The test is performed continuously when the supply to the LIN nodes is active.
Possible cause
There may be an internal error in the actuators or an error in the cable harness.
