Steering Angle Sub Control Module: Fail-Safe

WARNING: This page is about a different car, the 2016 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.

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 .
