P317A Nissan Code - Traction Motor Inverter Pulse Width Modulation OFF Request
Quick Answer
The P317A code for Nissan vehicles indicates a "Traction Motor Inverter Pulse Width Modulation OFF Request." In hybrid and electric vehicles, the traction motor inverter plays a crucial role in converting the direct current (DC) from the battery into alternating current (AC) to power the electric motor. Common causes include Faulty traction motor inverter, Wiring or connection issues in the PWM circuit, Software glitches or programming errors. 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.
