RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT DEF RELAY


    1. A01RF4X

      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 DEF relay.

  2. INSPECT HWD NO. 1 RELAY


    1. A01REH4

      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.

  3. INSPECT HWD NO. 2 RELAY


    1. A01REH4

      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.

  4. INSPECT HWD NO. 3 RELAY


    1. A01RF4X

      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.
