Wiring Diagram - Bilstein DampTronic SYSTEM -
Fail-safe
Bilstein DampTronic system- When detecting any malfunction in each component of the system, it enters the fail-safe status (the Bilstein DampTronic system control is deactivated).
- At the same time when the system enters the control stop status, it becomes the equivalent status to R mode (fixed damping status).
- Even if the set-up switch (suspension) is operated in the fail-safe status, no lamp illuminates in R mode or COMFORT mode.
DTC Inspection Priority Chart
When multiple DTCs are detected simultaneously, check one by one depending on the following priority list.
