Diagnostic Information and Procedures
Self-Diagnosis Function for Headlight Auto Leveling SystemS6RW0D9204014
The headlight leveling control module has self-diagnosis function to monitor the system components and circuits while
the headlight auto leveling system is at work. When the headlight leveling control module detects an abnormality in the
system, the headlight leveling warning light in the combination meter turns ON. However, the headlight leveling control
module does not have a function to indicate location of such abnormality.
