Monitor Result

Refer to detailed information (See READINESS MONITOR DRIVE PATTERN ).

The test value and test limit information are described as shown in THERMOSTAT UNIT CONVERSION . Check the monitor result and test values after performing the monitor drive pattern (Refer to "Confirmation Monitor").

TID (Test Identification Data) is assigned to each emissions-related component.
TLT (Test Limit Type):
If TLT is 0, the component is malfunctioning when the test value is higher than the test limit.

If TLT is 1, the component is malfunctioning when the test value is lower than the test limit.
CID (Component Identification Data) is assigned to each test value.
Unit Conversion is used to calculate the test value indicated on generic OBD II scan tools.
