Cooling Fan Relay -- On-Vehicle Inspection



1. INSPECT COOLING FAN RELAY


Lexus Is250, Is220D. Gse20 Ale20

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    3 - 5
    		10 MΩ or higher
    3 - 5
    		Below 1 Ω
    (when battery voltage is applied to terminals 1 and 2)
    Measure the resistance according to the value(s) in the table below.


2. INSPECT NO. 2 COOLING FAN RELAY


Lexus Is250, Is220D. Gse20 Ale20

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    3 - 4
    		Below 1 Ω
    3 - 5
    		10 MΩ or higher
    3 - 5
    		Below 1 Ω
    (when battery voltage is applied to terminals 1 and 2)
    If the result is not as specified, replace the No.2 cooling fan relay.


3. INSPECT NO. 3 COOLING FAN RELAY


Lexus Is250, Is220D. Gse20 Ale20

  1. Inspect the resistance of the relay.

    Standard resistance:
    Tester Connection
    		Specified Condition
    3 - 5
    		10 MΩ or higher
    3 - 5
    		Below 1 Ω
    (when battery voltage is applied to terminals 1 and 2)
    If the result is not as specified, replace the No.3 cooling fan relay.
