On-Vehicle Inspection

  1. INSPECT STOP LIGHT CONTROL RELAY (BRK-LP) 
    1. Remove the stop light control BRK-LP relay.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      STANDARD RESISTANCE

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

      If the value is not as specified, replace the stop light control BRK-LP relay
