Checking Monitor Status
CHECKING MONITOR STATUSHINT: "MONITOR RESULT" indicates normal or malfunction of each component and system when judgment has done.
1. HOW TO READ DATA
a. Connect the hand-held tester to the DLC 3.
b. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / MONITOR INFO / MONITOR RESULT The Test ID will appear at the beginning of each line, followed by INCMP, PASS, or FAIL.
HINT:
- INCMP: Stands for "incomplete".The judgement has not been done yet.
- PASS: Normal is detected.
- FAIL: A malfunction has been detected.
c. Select a Test ID that you want from the list and press the "ENTER" button. You will see the following screen:
1. VAL (TEST VALUE) [Test Data] [Unit]
2. LMT (TEST LIMIT) [Test Limit] [Unit]
3. TLT [Test Limit Type]
d. By pressing the "HELP" button, you can see more information.
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 might detect malfunction on a previous trip, and then passed on the most recent trip. This would indicate an intermittent problem may be the cause of the DTC.
