    1. E145141E06

      Disconnect the connector from the heater switch assembly.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester connection

      Condition

      Specified condition

      4 (IG) - 1 (IN)

      Heater switch ON

      Below 1 Ω

      4 (IG) - 1 (IN)

      Heater switch OFF

      10 kΩ or higher

      If the result is not as specified, replace the heater switch assembly.

    3. Check that the heater switch assembly operation indicator comes on.

      1. Connect the positive (+) lead from the battery to terminal 1 (IN) and the negative (-) lead to terminal 5 (E), and check that the operation indicator comes on.
