Diagnosis Description
FUNCTION
| Diagnostic test mode | Function |
|---|---|
| Self Diagnostic Result | Self-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame data can be read and erased quickly.* |
| Data Monitor | Input/Output data in the ECM can be read. |
| Work support | This mode enables a technician to adjust some devices faster and more accurately by following the indications on the CONSULT unit. |
| Active Test | Diagnostic Test Mode in which CONSULT drives some actuators apart from the ECMs and also shifts some parameters in a specified range. |
| ECU Identification | ECM part number can be read. |
| DTC Work Support | The status of system monitoring tests and the self-diagnosis status/results can be confirmed. |
*: The following emission-related diagnostic information is cleared when the ECM memory is erased.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
SELF DIAGNOSTIC RESULT MODE
Self Diagnostic Item
Regarding items of DTC and 1st trip DTC, Refer to DTC Index .
How to Read DTC and 1st Trip DTC
DTCs and 1st trip DTCs related to the malfunction are displayed in "Self-diag results".
- When ECM detects a 1st trip DTC, "1t" is displayed for "TIME".
- When ECM has detected a current DTC, "0" is displayed for "TIME".
- If "TIME" is neither "0" nor "1t", the DTC occurred in the past and ECM shows the number of times the vehicle has been driven since the last detection of the DTC.

SRT and P-DTC MODE
SRT STATUS Mode
- For items whose SRT codes are set, "CMPLT" is displayed on the CONSULT screen; for items whose SRT codes are not set, "INCMP" is displayed.
- "SRT STATUS" provides the presence or absence of permanent DTCs stored in ECM memory.
PERMANENT DTC STATUS Mode
How to Display Permanent DTC Status
- Turn ignition switch OFF and wait at 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at 10 seconds.
- Turn ignition switch ON.
- Select "PERMANENT DTC STATUS" in "DTC and SRT CONFIRMATION" mode with CONSULT.NOTE: Permanent DTCs stored in ECM memory are displayed on the CONSULT screen to show if a driving pattern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).CAUTION:
Since the "PERMANENT DTC STATUS" screen displays the previous trip information, repeat the following twice to update the information: "Ignition switch OFF", "Wait for more than 10 seconds" and "Ignition switch ON".
SRT WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to set the SRT while monitoring the SRT status.
PERMANENT DTC WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to complete the driving pattern that is required for erasing permanent DTC.
