•
The on-board diagnostic system consists of a malfunction detection system that detects abnormalities in input/
output signals when the ignition switch is at the ON position, a data monitor function that reads out specified
input/output signals and a simulation function that allows for override operation of output parts (such as
solenoid valves).
•
The data link connector 2 (DLC-2), which groups together all the connectors used for malfunction diagnosis
and detecting/repair into a single location, has been adopted, thereby improving serviceability. Diagnosis is
performed by connecting the WDS or equivalent to the DLC-2.
•
In addition to DTC read-out, the WDS or equivalent is used to clear DTCs using the display screen of the
diagnostic tester, and to access the PID/data monitor and simulation functions, providing enhanced
malfunction diagnosis and improved serviceability.
