      HINT:

      • Monitor test results can be viewed in the MONITOR RESULT screen.
      • Monitor test results indicate the latest malfunction judgement result of this diagnostic.
      • TEST VALUE indicates the detection parameter value (Example: P0128 Thermostat Malfunction = Engine coolant temperature) at the time of malfunction (or normal) judgement is done.
      • TEST LIMIT indicates a threshold of malfunction judgement (Example: P0128 Thermostat Malfunction = 75°C).
      • When the monitor runs, the monitored Parameter's VALUE is recorded. The value is then compared to the TEST LIMIT to determine if the result is PASS or FAIL.
      • By comparing the Parameter VALUE to the TEST LIMIT, it is possible to determine the degree of failure.
