•
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 and is used to
set the system to the neutral position.
•
The Data Link Connector 2 (DLC-2), which groups together all the connectors used for malfunction diagnosis
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 data monitor and simulation functions, providing enhanced malfunction
diagnosis and improved serviceability.
