RELAY ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT STARTER RELAY (ST)

   
   

   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 relay.

2. INSPECT NO. 1 GLOW RELAY (GLOW 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 relay.

3. INSPECT NO. 2 GLOW RELAY (GLOW NO. 2)

   
   

   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 starter relay.

4. INSPECT MAIN BODY ECU (ACC RELAY)

   Tech Tips

   Before performing the relay inspections for the relay of the main body ECU, inspect the ECU-ACC NO. 1 fuse.

   
   

   1. Measure the resistance of the ACC relay circuit.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 2G-1 - 2H-9 Battery voltage not applied between 2J-18 and 2J-1 10 kΩ or higher Battery voltage applied between 2J-18 and 2J-1 Below 1 Ω
