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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E138-7 (ECU) - F76-7 (BLSW) Always Below 1 Ω
      E138-7 (ECU) or F76-7 (BLSW) - Body ground Always 10 kΩ or higher
    4. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E138-1 (IG) - Body ground Engine switch on (IG) 11 to 14 V
      E138-1 (IG) - Body ground Engine switch off Below 1 V
