1. Check the hold-in coil for continuity between the S terminal and the armature housing (ground). There should be continuity.
   - If there is continuity, go to Step 2 .
   - If there is no continuity, replace the solenoid.

1. Check the pull-in coil for continuity between the S terminal and M terminal. There should be continuity.
   - If there is continuity, the solenoid is OK.
   - If there is no continuity, replace the solenoid.
