Meaning of fuel system loop status
•  The following information is displayed on the tester
―  Feedback stops: ECT is lower than the determined feedback zone
―  Feedback operating: A/F sensor, HO2S being used for feedback is normal
―  Feedback stops: Open loop due to driving condition
―  Feedback stops: Open loop due to detected system fault
―  Feedback operating: Malfunction occurred in HO2S system


Sending Freeze Frame Data (Mode 02)

Freeze frame data
•  The freeze frame data consists of data for vehicle and engine control system operation conditions when malfunctions in the engine control system are detected and stored in the PCM.
•  Freeze frame data is stored at the instant the malfunction indicator lamp illuminates, and only a part of the DTC data is stored.
•  For the freeze frame data, if there are several malfunctions in the engine control system, the data for the malfunction which occurred initially is stored. Thereafter, if a misfire or fuel injection control malfunction occurs, data from the misfire or fuel injection control malfunction is written over the initially stored data. However, if the initially stored freeze frame data is a misfire or fuel injection control malfunction, it is not overwritten.
Snapshot data
•  The snap shot data stores the currently detected DTC data.
•  The recording timing for the freeze frame data/snap shot data differs depending on the number of DTC drive cycles.
―  For a DTC with a drive cycle number 1, only the malfunction determination data is recorded.
―  For a DTC with a drive cycle number 2, both the malfunction determination and undetermined data is recorded.

Sending Continuous Monitoring System Test Results (pending code) (Mode 07)

•  These appear when a problem is detected in a monitored system.

1-drive cycle type

•  If any problems are detected in the first drive cycle, pending codes will be stored in the PCM memory, as well as DTCs.
•  After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.


2-drive cycle type

•  The code for a failed system is stored in the PCM memory in the first drive cycle. If the PCM determines that the system returned to normal or the problem was mistakenly detected, and deletes the pending code. If the problem is found in the second drive cycle too, the PCM determines that the system has failed, and stores the pending codes, and the DTCs.
•  After pending codes are stored, if the PCM determines that the system is normal in any future drive cycle, the PCM deletes the pending codes.
