Supercharger Bypass Actuator Circuit Open

on 2017 Maserati Levante 3.0L V6 Twin Turbo · AWD

What this code means

The supercharger bypass actuator that controls airflow around the supercharger for efficiency is not responding due to an open circuit.

Symptoms

  • Check Engine Light
  • Supercharger always pumping air (no bypass)
  • Higher parasitic load on engine
  • Reduced fuel economy at cruise
  • Supercharger whine present at all times

Common causes

  • Bypass actuator motor open circuit
  • Wiring harness disconnected
  • Connector pin backed out
  • Actuator failed internally
  • PCM driver circuit blown

Diagnostic steps

  1. Test bypass actuator motor resistance
  2. Check wiring continuity to actuator
  3. Inspect connector for backed-out pins
  4. Command actuator via scan tool
  5. Measure PCM output voltage at actuator

Repair notes

Replace supercharger bypass actuator or repair wiring. Verify bypass operates correctly at low load conditions.
