ID sensor error 3
For 2 s during the ID sensor pattern
check, the ID sensor pattern edge
voltage is not 2.5V or the pattern edge
is not detected within 800 ms.

ID sensor error 4
One of the following ID sensor output
voltages is detected at ID sensor
initialization.
• Vsg < 4.0V when the maximum
PWM input (255) is applied to the ID
sensor.
• Vsg ≥ 4.0V when the minimum
PWM input (0) is applied to the ID
sensor.
