1. INSPECT SEAT HEATER SWITCH


E106727E02

  1. Disconnect the L40 switch connector.

  1. Measure the resistance of the switch.

    Standard resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    1 - 6
    		Front LH side seat heater switch OFF (volume 0)
    		10 kΩ or higher
    1 - 6
    		Front LH side seat heater switch ON (volume 1)
    		Approx. 2.4 kΩ
    1 - 6
    		Front LH side seat heater switch ON (volume 3)
    		Approx. 0.4 kΩ
    2 - 11
    		Front RH side seat heater switch OFF (volume 0)
    		10 kΩ or higher
    2 - 11
    		Front RH side seat heater switch ON (volume 1)
    		Approx. 2.4 kΩ
    2 - 11
    		Front RH side seat heater switch ON (volume 3)
    		Approx. 0.4 kΩ

    HINT:
    As the dial is being turned, the resistance changes gradually.

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

  1. Connect the battery's positive (+) lead to terminal 4 (ILL+) and the negative (-) lead to terminal 12 (E).

  1. Check the indicator light.

    OK:
    Condition
    		Specified Condition
    Front LH side seat heater switch ON
    		Front LH side seat heater indicator light illuminates
    Front RH side seat heater switch ON
    		Front RH side seat heater indicator light illuminates

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