Note:
The test results will be lost if the ignition switch is turned off.
The test value is usually not near the test limits. If the test value is near the test limits, the component is likely to malfunction in the near future.
Hint:
The monitor result might on rare occasions be pass even if the malfunction indicator lamp (mil) is illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused by an intermittent problem.
If you use a generic scan tool, multiply the test value by the scaling value listed below.
