Diagnosis System
DIAGNOSIS SYSTEMThe ECM controls the immobilizer function of the vehicle.
The data of the immobilizer or 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 or SST to check and troubleshoot it.
