REAL TIME DIAGNOSIS IN DATA MONITOR MODE (RECORDING VEHICLE DATA) Description: Notes

CONSULT-II has two kinds of triggers and they can be selected by touching "SETTING" in "DATA MONITOR" mode.

  1. "AUTO TRIG" (Automatic trigger):
    • The malfunction will be identified on the CONSULT-II screen in real time.

      In other words, DTC/1st trip DTC and malfunction item will be displayed if the malfunction is detected by ECM.

      At the moment a malfunction is detected by ECM, "MONITOR" in "DATA MONITOR" screen is changed to "Recording Data ... xx%" as shown in the figure, and the data after the malfunction detection is recorded. Then when the percentage reached 100%, "REAL-TIME DIAG" screen is displayed. If "STOP" is touched on the screen during "Recording Data ... xx%", "REAL-TIME DIAG" screen is also displayed.

      The recording time after the malfunction detection and the recording speed can be changed by "TRIGGER POINT" and "Recording Speed". Refer to CONSULT-II Operation Manual.

  2. "MANU TRIG" (Manual trigger):
    • DTC/1st trip DTC and malfunction item will not be displayed automatically on CONSULT-II screen even though a malfunction is detected by ECM.

      DATA MONITOR can be performed continuously even though a malfunction is detected.
