TCM diagnostic mode

Description

Self Diagnostic Result

Retrieve DTC from ECU and display diagnostic items.

Data Monitor

Monitor the input/output signal of the control unit in real time.

CAN Diagnosis

The condition of CAN communication can be indicated by a topology.

CAN Diagnosis Support Monitor

It monitors the status of CAN communication.

DTC & SRT Confirmation

The status of system monitoring tests and the self-diagnosis status/result can be confirmed.

Function Test*

This mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For engines, more 
practical tests regarding sensors/switches and/or actuators are available.

Ecu Identification

Display the ECU identification number (part number etc.) of the selected system.
