Diagnostic Instructions

This information needs to be used in conjunction with the monitor descriptions and data setting information. This gives the background on entry conditions and test limits.
Not all scan tools work the same way when outputting Mode 6 test data. Some report the raw values, some just report pass or fail.
Bit 7 of the Component ID identifies if a passing value must exceed the threshold and many scan tools take this into account when reporting mode 6 information. For example, the Bank 1 Sensor 1 response rate minimum check maybe reported with a component ID of 1, but the scan tool will in this instance show or interpret a test value that is below the threshold as failing and a value that exceeds the threshold as passing.
