INTAKE SHUTTER SOLENOID VALVE INSPECTION [MZR-CD (RF Turbo)]

BME011618740206

  Note

  • Perform the following inspection only when directed.
  • The inspection includes both intake shutter solenoid valve (half) and intake shutter solenoid valve (full).

1. Inspect airflow between the ports under the following conditions.

  • If not as specified, replace the intake shutter solenoid valve.
  • If as specified, carry out the "Circuit open/Short Inspection".

## Intake Shutter Solenoid Valve (Half) Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Inspect the following wiring harness for open or short (continuity check).

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the harness.
  - Intake shutter solenoid valve (half) terminal A (harness-side) and PCM control relay terminal C (harness-side)
  - Intake shutter solenoid valve (half) terminal B (harness-side) and PCM terminal 74

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - Intake shutter solenoid valve (half) terminal B (harness-side) and GND
  - Intake shutter solenoid valve (half) terminal B (harness-side) and power supply

## Intake Shutter Solenoid Valve (Full) Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2. Inspect the following wiring harness for open or short (continuity check).

### Open circuit

  • If there is no continuity, the circuit is open. Repair or replace the harness.
  - Intake shutter solenoid valve (full) terminal A (harness-side) and PCM control relay terminal C (harness-side)
  - Intake shutter solenoid valve (full) terminal B (harness-side) and PCM terminal 100

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - Intake shutter solenoid valve (full) terminal B (harness-side) and GND
  - Intake shutter solenoid valve (full) terminal B (harness-side) and power supply
