P317A Code - Traction Motor Inverter Pulse Width Modulation OFF Request
Quick Answer
The Diagnostic Trouble Code (DTC) will be set when the Hybrid Powertrain Control Module (HPCM)detects a self-diagnosis signal from the traction motor inverter requesting the Pulse Width Modulation (PWM) to be turned off. Common causes include Faulty Traction Motor Inverter, Traction Motor Inverter harness is open or shorted, Traction Motor Inverter 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.
