   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.
   • In rare cases, the monitor may have passed even with a DTC set and MIL illuminated. The monitor possibly detect malfunction on a previous trip, and then passed on the most recent trip. This would indicate an intermittent problem that may be the cause of the DTC.
