I did some more checking I hope this helps.
OBD II Connectors
Kia vehicles typically have two Diagnostic
OBD II Connector - Conforms to standard SAE J1962, which defines requirements for the
connector location, design, terminal assignments and electrical interface
requirements. The connector has sixteen pins and is located in the passenger compartment on the driver's side of the dash under the knee
pad. Power to the Scan Tool is continuously provided by pin 16. The Kia Hi-Scan Pro Scan Tool DLC Cable 16 (P/N 09900-21100) will mate with this connector. For all Kia OBD II compliant vehicles, engine and transmission data are available at this connector. ABS, Traction Control System and SRS data are also available at this connector on some newer models, such as 2001 Optima (for earlier models like 2000 Sephia, this data must be retrieved from the Kia Diagnostic Connector underhood).
Kia 20-pin Diagnostic Connector - Most Kia
vehicles have this Kia-specific connector, which is located in the engine compartment.The Scan Tool requires DLC Cable Adapter (P/N 09900- 29020) to connect. OBD II engine and transmission data are available at this connector.
On some Kia vehicles, this connector provides the only access to ABS,Traction Control System and SRS data. On some vehicles, data from those systems are also available at the OBD II connector, but the underhood connector does have testing circuits and capabilities that the OBD II connector does not have. Relays, keyless
entry and the fuel pump circuit can also be accessed here.
The law also requires that the vehicle
manufacturer design the diagnostic system in
a manner that permits retrieval of OBD II data
in a standard format using any available
generic scan tool using one of four data
• SAE J1850 VPW
- (Used by GM, 10.4k Baud data transfer
• SAE J1830 PWM
- (Used by Ford, 41.7k Baud data
• ISO 9141-2 CARB
- (Used by most Kia, and other
and Asian, 10.4k Baud data transfer
• ISO 14230-4 KWP 2000
- (Used by 2001 Kia Optima V6,
19.2-115.2K Baud data transfer rate)
