Sending Diagnostic Data (Mode 01)

PID data monitor

•  The PID data monitor items are shown below.

PID data monitor table

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)

―  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.

Status Byte for DTC

•  The status byte is the two-digit code (two digits after hyphen (-)) after the DTC.

am3uun00002230

Sending Emission-related Malfunction Code (DTC) (Mode 03)

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

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.
