id0302001001a6
• The on-board diagnostic function allows for detecting malfunctions in the input/output signals when the ignition key is at the ON position.
• The DLC-2, which combines the failure detection and detection maintenance connectors, has been adopted to improve serviceability. By connecting a WDS or equivalent to the DLC-2, malfunction diagnosis can be carried out.
• Using a WDS or equivalent DTCs can be retrieved or erased, depending on the screen display, thus improving serviceability.
