Cause:
If this error light comes on and service icons appear on the dashboard, then to clear it, you need to check the operation of the electric motor of the valve lift adjustment mechanism. To reset the code, you must determine the cause of the open circuit. The engine started, the motor is running, and the PCM detected a high voltage present at the PCM for 3 minutes after the engine started. The high voltage test of the starter relay control circuit monitors the voltage signal sent by the ignition switch.
