Drive Motor B Inverter Performance
The drive motor B inverter does not deliver the expected power conversion. Switching loss elevated, gate driver fault, or capacitor degraded.
Affected components
- Drive motor b inverter
- Hybrid control module
Common causes
- High likelihood: IGBT switching characteristic degraded
- Medium likelihood: DC-link capacitor aged
Possible symptoms
- EV/hybrid system warning light on
- Reduced motor power or torque
- Possible limp mode or vehicle shutdown
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
