   Standard resistance: 29 - 35 Ω. 

   If resistance value is not as specified, replace the solenoid.

3. Apply battery positive voltage between terminals. Check that operation.

If the solenoid does not operated, replace the solenoid noise can be heard from the solenoid.

1. Disconnect the solenoid connector.
2. Using an ohmmeter, measure resistance between terminals.

   Standard resistance: 12.5 - 16.5 Ω. 

   If resistance value is not as specified, replace the solenoid.

3. Apply battery positive voltage between terminals. Check that an operation noise can be heard from the solenoid.
