DescriptionINFOID:0000000003856765
ECM receives two vehicle speed signals via the CAN communication line. One is sent from “ABS actuator and
electric unit (control unit)” via combination meter, and the other is from TCM (Transmission control module).
ECM uses these signals for engine control.

Engine speed will not

due to the fuel cutMalfunction indicator
circuitWhen there is an open circuit on MI circuit, the ECM cannot warn the
driver by illuminating MI when there is malfunction on engine control
system.
Therefore, when electrical controlled throttle and part of ECM related
diagnoses are continuously detected as NG for 5 trips, ECM warns the
driver that engine control system malfunctions and MI circuit is open by
means of operating the fail-safe function.
The fail-safe function also operates when above diagnoses except MI
circuit are detected and demands the driver to repair the malfunction.EC-346

How to Set SRT CodeINFOID:0000000003856873
To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. Each
diagnosis may require a long period of actual driving under various conditions.
WITH CONSULT-III
Perform corresponding DTC Confirmation Procedure one by one based on Performance Priority in the table
on “SRT Item”.
