C15A9 Code - Lock Holder Deviation Detection
Quick Answer
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. Common causes include Faulty Steering Actuator, Steering Actuator harness is open or shorted, Steering Actuator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
