RELAY ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT NO. 1 INTEGRATION RELAY (IG2)

   1. Measure the resistance of the IG2 fuse.

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

         Standard Resistance

         Tester Connection	Condition	Specified Condition
         IG2 Fuse	Always	Below 1 Ω

         If the result is not as specified, replace the IG2 fuse.

   2. 

      Measure the resistance of the IG2 relay.

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

         Standard Resistance

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

         Table 1. Text in Illustration

         *a	Component without harness connected (No. 1 Integration Relay)

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

2. INSPECT NO. 1 INTEGRATION RELAY (FUEL PUMP)

   1. Measure the resistance of the FUEL PUMP fuse.

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

         Standard Resistance

         Tester Connection	Condition	Specified Condition
         FUEL PUMP Fuse	Always	Below 1 Ω

         If the result is not as specified, replace the FUEL PUMP fuse.

   2. 

      Measure the resistance of the FUEL PUMP relay.

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

         Standard Resistance

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

         Table 2. Text in Illustration

         *a	Component without harness connected (No. 1 Integration Relay)

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

3. INSPECT EFI MAIN RELAY (EFI MAIN)

   

   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
      3 - 5	Battery voltage applied to terminals 1 and 2	Below 1 Ω

      If the result is not as specified, replace the EFI MAIN relay.

4. INSPECT FUEL FILTER RELAY (FUEL FILTER)

   

   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
      3 - 5	Battery voltage applied to terminals 1 and 2	Below 1 Ω

      If the result is not as specified, replace the FUEL FILTER relay.
