RELAY ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT NO. 1 COOLING FAN RELAY (FAN NO. 1)

   1. 

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

      Standard Resistance

      Tester Connection	Condition	Specified Condition
      3 - 5	Battery voltage not applied to terminals 1 and 2	10 kΩ or higher
      	Battery voltage applied to terminals 1 and 2	Below 1 Ω

      If the result is not as specified, replace the No. 1 cooling fan relay.

2. INSPECT NO. 2 COOLING FAN RELAY (FAN NO. 2)

   1. 

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

      Standard Resistance

      Tester Connection	Condition	Specified Condition
      3 - 4	Battery voltage not applied between terminals 1 and 2	Below 1 Ω
      	Battery voltage applied between terminals 1 and 2	10 kΩ or higher
      3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
      	Battery voltage applied between terminals 1 and 2	Below 1 Ω

      If the result is not as specified, replace the No. 2 cooling fan relay.

3. INSPECT NO. 3 COOLING FAN RELAY (FAN NO. 3)

   1. 

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

      Standard Resistance

      Tester Connection	Condition	Specified Condition
      3 - 5	Battery voltage not applied to terminals 1 and 2	10 kΩ or higher
      	Battery voltage applied to terminals 1 and 2	Below 1 Ω

      If the result is not as specified, replace the No. 3 cooling fan relay.
