DC/AC Converter Control Module Control Circuit Range/Performance
The control circuit for the DC/AC converter (used in plug-in hybrid and EV traction systems to convert DC battery voltage to 3-phase AC for the motor) reports a performance issue. This is part of the high-voltage drivetrain.
Affected components
- Inverter
- Traction motor
Common causes
- High likelihood: Inverter internal fault
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
