Checking Monitor Status

CHECKING MONITOR STATUS

HINT: "MONITOR RESULT" indicates normal or malfunction of each component and system when judgment has done.

a. HOW TO READ DATA (using the hand-held tester)




1. Connect the hand-held tester to the DLC3.
2. Enter the following menus: "MONITOR RESULT" from "DIAGNOSIS / ENHANCED OBD II / MONITOR INFO / MONITOR RESULT" the Test ID will appear at the beginning of each line, following by INCMP, PASS or FAIL.

HINT:
- INCMP: Stands for "incomplete" the diagnosis is incomplete.
- PASS: The component or system is operating normally.
- FAIL: A malfunction has been detected.




3. Select a Test ID that you want from the list and press the "ENTER" button. You will see the following screen:
- VAL (TEST VALUE) [Test Data] [Unit]
- LMT (TEST LIMIT) [Test Limit] [Unit]
- TLT [Test Limit Type]

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 (167°F)).
- 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 may have failed on a previous trip, and then passed on the most recent trip. This would indicated an intermittent problem may be the cause of the DTC.
