         If the result is not as specified, replace the integration relay.

   4. Install the integration relay Click here.

3. INSPECT NO. 1 IGNITION RELAY (IG1)

   
   

   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 relay.

4. INSPECT NO. 2 IGNITION RELAY (IG2)

   
   

   1. Remove the integration relay Click here.

   2. 

      *1	Fuse Side
      *2	Connector Side

      Check 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.

   3. Check 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 1A-1 - 1A-4 1C-1 - 1A-4 Battery voltage applied to terminals 1A-2 and 1A-3 Below 1 Ω 1A-1 - 1A-4

         If the result is not as specified, replace the integration relay.

   4. Install the integration relay Click here.

5. INSPECT CIRCUIT OPENING RELAY (C/OPN)

   Note

   The circuit opening relay is built into the main body ECU (instrument panel junction block).

   
   

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

      

      Text in Illustration

      *1	Component without harness connected (Main Body ECU)
