CONSULT Function

APPLICABLE ITEM 

Mode Function
All DTC Reading Display all DTCs or diagnostic items that all ECUs are recording and judging.
CAN Diagnosis This mode displays a network diagnosis result about CAN by diagram.
CAN Diagnosis Support Monitor It monitors the status of CAN communication.
Self Diagnostic Results The ECU self diagnostic results are displayed.
Data Monitor The ECU input/output data is displayed in real time.
ECU Identification The ECU part number is displayed.

SELF DIAGNOSTIC RESULTS 

Display Item List 

Refer to DTC Index .

How to Read DTC 

DTC is displayed on "Self Diagnostic results" of CONSULT. When DTC is currently detected, "CRNT" is displayed. If "PAST" is displayed, it shows a malfunction occurred in the past. The trip number of drive without malfunction of concerned DTC can be confirmed with "IGN counter" inside "FFD".

How to Erase DTC 

NOTE: SYMBOL If the ignition switch is left ON after repair, turn OFF the ignition switch and wait for 10 seconds or more. Then, turn the ignition ON again. (Engine stop)
  1. Touch "SHIFT" of CONSULT.
  2. Touch "Self Diagnostic Result".
  3. Touch "Erase". (DTC memorized in electric shift control module is erased.)

Freeze Frame Data (FFD) 

The following vehicle status is recorded when DTC is detected and is displayed on CONSULT.

Monitored item Displayed contents
ODO/TRIP METER Displays the mileage at the time the malfunction is detected.
