Operation inspection

CAUTION:

Do not apply voltage to a solenoid valve for 3 s or more to prevent damaging it.

NOTE:

Perform the inspection in a quiet place because the operation sound of solenoid valve may be difficult to hear.

Disconnect the coupler component connector.
1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [MZR 2.5] .)
2. Disconnect the negative battery cable.
3. Disconnect the coupler component connector.
  
  Fig 1: Identifying Coupler Component
Apply the battery voltage between the GND and each terminal of A and B and verify the solenoid valve operation sound.

- If the operation sound cannot be verified, inspect the solenoid valve continuity.
- If there is any malfunction in the coupler component, inspect the solenoid valve individually. (See PART INSPECTION .)
