Toyota Corolla Repair Manual: Inspection

1. Cooling fan relay

  1. Inspect the cooling fan relay continuity.
  1.  Using an ohmmeter, check that there is continuity between terminals 1 and 2.

    If there is no continuity, replace the relay.

  2.  Check that there is no continuity between terminals 3 and 5.

    If there is continuity, replace the relay.

  3.  Apply battery voltage across terminals 1 and 2.
  4.  Using an ohmmeter, check that there is continuity between terminals 3 and 5.

    If there is no continuity, replace the relay.
