3. 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 5.
- If there is no continuity, replace the solenoid.

4. Check the pull-in coil for continuity between the S terminal and the M terminal. There should be continuity.

- If there is continuity, the solenoid is OK.
- If there is no continuity, replace the solenoid.

5. Install the wire and the connector in the reverse order of removal.

6. Do the battery terminal reconnection procedure Procedures.
