SHIFT SOLENOID B INSPECTION [AY6A-EL, AY6AX-EL]

id0517k3299700

  Warning
  • Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air.

  Caution
  • Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
  • Do not damage the terminals.

On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

4. Measure the resistance between coupler component terminal B2 and GND.

  • If there is any malfunction, inspect the coupler component for continuity. (See COUPLER COMPONENT INSPECTION [AY6A-EL, AY6AX-EL].)
  • If coupler component has no malfunction, perform the “Off-Vehicle Inspection“. (See Off-Vehicle Inspection.)

Operation inspection

  Caution
  • Do not apply battery positive voltage to terminals for more than 3 s.

  Note
  • Because the operation sound of the shift solenoid B is small, perform inspection in a quiet place.

1. Connect the shift solenoid B terminal B to the battery positive terminal, connect the battery negative terminal to solenoid body.

  Caution
  • Do not apply impact to shift solenoid B.
  • Do not damage the terminals.

2. Verify that operating sound is heard from the shift solenoid B.

  • If there is any malfunction, replace the shift solenoid B.

Airflow inspection

1. Connect the shift solenoid B terminal B to the battery positive terminal, connect the battery negative terminal to solenoid body.

  Caution
  • Do not apply impact to shift solenoid B.
  • Do not damage the terminals.

2. Blow compressed air to inspect the condition of the airflow shown in the figure.
