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

         Standard Voltage
         Tester Connection Switch Condition Specified Condition A49-1 (B) - A49-3 (GND) Always 11 to 14 V A49-2 (L) - A49-3 (GND) Ignition switch ON (IG) 11 to 14 V A49-2 (L) - A49-3 (GND) Ignition switch off 0 V

         If the result is not as specified, repair or replace the wire harness.

   3. Check the resistance.

      
      

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

         Standard Resistance
         Tester Connection Switch Condition Specified Condition A49-3 (GND) - Body ground Always Below 1 Ω

   5. Check the voltage.

      
      

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

         Standard Voltage
         Tester Connection Switch Condition Specified Condition A49-2 (L) - A49-3 (GND) Ignition switch off, brake pedal not depressed Below 1 V A49-2 (L) - A49-3 (GND) Ignition switch off, brake pedal depressed 11 to 14 V

         If the result is not as specified, replace the stop light switch assembly.
