Magnetic Switch Operation Inspection

WARNING: This page is about a different variant/trim than selected.

Pull-out test 

NOTE:
  • Depending on the battery charge condition, the starter motor pinion may rotate while in an extended state. This is due to current flowing to the starter motor through the pull-in coil to turn the starter motor, and does not indicate an abnormality.
  1. Verify that the starter motor pinion is extended while battery positive voltage is connected to terminal S and the starter body is grounded.

    • If the starter motor pinion is not extended, repair or replace the starter.

Return test 

  1. Disconnect the motor wire from terminal M.
  2. Connect battery positive voltage to terminal M and ground the starter body.

    • If it does not return, repair or replace the starter.

Pinion Gap Inspection 

  1. Pull out the drive pinion with the battery positive voltage connected to terminal S and the starter body grounded.
