This function minimizes the loss of the ECT functions when a malfunction occurs in each sensor or solenoid.

Check mode has a higher sensitivity to malfunctions and can detect malfunctions that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect. In check mode, DTCs are stored with 1 trip detection logic.

DTCs which are stored in the ECM can be output to the GTS.

The GTS can display pending DTCs and current DTCs. Some DTCs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending DTC.

When troubleshooting On-Board Diagnostic (OBD II) vehicles, the vehicle must be connected to the OBD II scan tool (complying with SAE J1987). Various data output from the vehicle ECM can then be read.

Using an oscilloscope, check waveform 1.
