OBD Pending DTCs
Pending DTCs are DTCs that have only set during one drive cycle and may not have set the MIL yet. These DTCs can be identified using the retrieve pending DTCs feature. Additionally, they are found in the vehicle specific mode retrieve/clear continuous memory DTCs from the instant the DTC is set.
This function only reports pending concerns that have occurred during the present or previous drive cycle, but does not indicate single concerns that happened on any 2 previous drive cycles.
