Monitor Status: Notes

The Monitor Status (mode 6) allows the OBD scan tool to display the monitor result, test value and test limit (malfunction criterion). A problem in this component can be found by comparing the test value and test limit. This procedure is described under CHECKING MONITOR STATUS ).

• TID (Test Identification Data) is assigned to each emission-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 scan tools.
