DIAGNOSIS SYSTEM (ECM)
CONSULT Function
INFOID:0000000010289666
FUNCTION
*: The following emission-related diagnostic information is cleared when the ECM memory is erased.
• Diagnostic trouble codes
SELF-DIAGNOSTIC MODE
Self Diagnostic Item
Regarding items detected in “SELF-DIAG RESULTS” mode, refer to —
How to erase DTC
• If power is continuously in the ON position after a DTC is detected, turn power switch OFF before turning
power switch to the ON position again, and then erase DTC.
• Check the all self-diagnostic screen to confirm there are no DTCs in other ECUs.
Freeze Frame Data and 1st Trip Freeze Frame Data
The Freeze Frame Data shows the state of the vehicle at the time a DTC is detected and is useful in re-creat-
ing the circumstances that caused the malfunction.
NOTE:
The following table includes information (items) in applicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
Diagnostic test mode
Function
Self-diagnostic results
Self-diagnostic results such as DTC 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 and homologation number can be read.
Configuration
This function is used to store vehicle specifications to ECM after ECM replacement.
