Description of On-Board Diagnostics

DIAGNOSIS SYSTEM




ECM controls the function of immobilizer on this vehicle. Data of the immobilizer or DTC can be read form DLC3 of the vehicle. When a trouble occurs on immobilizer, MIL does not light on but DTC inspection is performed. Therefore when there seems to be a trouble on immobilizer, use hand-held tester or SST to check and troubleshoot it.
