2017 Infiniti Q60 Base, AWDFACTORY OEM SERVICE PROCEDURE
Direct Adaptive Steering: Fail-Safe
- If a malfunction occurs in the system, the fail-safe function stops the system (mode 3), activates the fail-safe mode (mode 1 or mode 2) or activates the protection mode. When the system enters mode 1, mode 2 or mode 3, the power steering warning lamp illuminates to inform the driver that the turning force is heavy in effect.
- Since three control modules monitor malfunctions mutually, DTC code varies from control module to control module.
- For details of protection function, refer to PROTECTION FUNCTION .
