Description of On-Board Diagnostics

DIAGNOSIS SYSTEM




ECM controls the function of the immobilizer on this vehicle.

Data of the immobilizers Diagnostic Trouble Code (DTC) can be read in the Data Link Connector 3 (DLC3) of the vehicle. When a trouble occurs in the immobilizer, Malfunction Indicator Lamp (MIL) does not come on but DTC inspection is performed.

Therefore when there seems to be a trouble with immobilizer, use the hand-held tester to check and troubleshoot it.
