RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT HEADLIGHT DIMMER RELAY


    1. A01V1SH

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied to terminal 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied to terminal 1 and 2 Below 1 Ω

      If the result is not as specified, replace the headlight dimmer relay.

  2. INSPECT HEADLIGHT RELAY


    1. A01UZWN

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied to terminal 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied to terminal 1 and 2 Below 1 Ω

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

  3. INSPECT FRONT FOG LIGHT RELAY


    1. A01V1SH

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied to terminal 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied to terminal 1 and 2 Below 1 Ω

      If the result is not as specified, replace the front fog light relay.

  4. INSPECT DAY TIME RUNNING LIGHT RELAY


    1. A01V1SH

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage not applied to terminal 1 and 2 10 kΩ or higher
      Auxiliary battery voltage applied to terminal 1 and 2 Below 1 Ω

      If the result is not as specified, replace the day time running light relay.

  5. INSPECT BACK UP LIGHT RELAY


    1. A01V1SH

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