- 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) judgment 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 with the TEST LIMIT to determine if the result is PASS or FAIL.
- By comparing the Parameter VALUE with the TEST LIMIT, it is possible to determine the degree of failure.
- In rare case, the monitor may have passed even with a DTC set and MIL illuminated. The monitor may have failed on a previous trip, and then passed on the most recent trip. This would indicate on intermittent problem may be the cause of the DTC.
