Code C15A4 Lexus Description

When the Variable Gear Ratio Steering (VGRS) system is normal, the steering actuator conducts current from the steering control ECU to the steering actuator solenoid to release the lock mechanism, enabling motor operation. The steering actuator does not operate under any of the following conditions:
- The engine switch is off.
- The motor in the actuator is locked by the lock mechanism to prevent rotation (fail-safe function).
- The system is being protected from overheating (fail-safe function).
If the steering control ECU detects a malfunction in the steering actuator lock mechanism or a motor rotation angle error, it will store this Diagnostic Trouble Code (DTC).
