Reading Diagnostic Trouble Codes

NOTE: This is the only information provided by the manufacturer for reading trouble codes for this system.

SELF-DIAGNOSIS
The ECM monitor the input/output signals (some signals at all times and the others under specified conditions). When the ECM detects an irregularity, it memorize the diagnostic trouble code, and outputs the signal to the self-diagnosis output terminal. The diagnosis results can be read out by the Generic Scan Tool (GST). Diagnostic trouble code (DTC) will remain in the ECM as long as battery power is maintained. The diagnostic trouble code will however, be erased when the battery negative terminal or the engine control module (ECM) connector is disconnected or erased by the Generic Scan Tool.

NOTE: HYUNDAI does not provide a procedure to retrieve diagnostic trouble codes without a scan tool.
