RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT DEF RELAY


    1. B0087PY

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

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

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

  2. INSPECT DEICER RELAY


    1. B0086MH

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

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

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

  3. INSPECT HWD NO. 1 RELAY


    1. B0089EW

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

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

      If the result is not as specified, replace the HWD NO. 1 relay.

  4. INSPECT HWD NO. 2 RELAY


    1. B0089EW

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

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

      If the result is not as specified, replace the HWD NO. 2 relay.

  5. INSPECT HWD NO. 3 RELAY


    1. B0086MH

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

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

      If the result is not as specified, replace the HWD NO. 3 relay.
