Switch Assembly Operation

WARNING: This page is about a different car, the 2016 Subaru Outback and 2016 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Perform the inspection in a short period of time. (Within 3 to 5 seconds)
  1. Loosen the nut which holds the M terminal to the starter body.
    NOTE: This procedure is required to facilitate the harness removal from the M terminal.

  2. Connect the battery positive terminal to the switch assembly S terminal, and connect the battery negative terminal to the starter body. Then, if the pinion protrudes, it is normal.
    NOTE: The starter motor may rotate while the pinion protrudes. This occurs due to current that flows to the motor via pull-in coil. This is not a problem.

  3. Disconnect the harness from the M terminal. Check that the pinion is being protruded at this time.
    CAUTION: Hold the disconnected harness so that it does not contact the terminal or wiring.
  4. Disconnect the battery negative terminal from the starter body. Then, if the pinion returns to its original position, it is normal.
