Description of On-Board Diagnostics
2000 Kia Sephia LS Sedan L4-1.8LSECTION Description of On-Board Diagnostics
The ABS control unit starts self-diagnostic functions after the ignition is switched ON. The ABS control unit detects failure for each circuit and component by comparing condition of the system with limited condition set inside the ABS control unit. The ABS control unit stores the failure code and then outputs the four-digit malfunction code to the diagnostic scan tool (Kia pro power scan tool) when the ABS diagnostic connector is connected.
