GROUP:	Electrical

SERVICE INFORMATION

On some 2012MY Optima (QF) vehicles built before September 22, 2011 equipped with stability control, the Stability Control Warning lamp may temporarily illuminate while performing a Dynamic Test Drive during PDI inspection. This may be caused by improperly tensioned pin terminals for the Yaw Rate Sensor circuit. If you experience this concern while performing the dynamic inspection, then a replacement of 4 pin terminals (19, 20, 21 and 22 at the EM61 connector) may be necessary to resolve this concern.

Perform the proper diagnostic test procedures for DTC C1282 found on KGIS prior to attempting this repair. Connector EM61 can be located on the lower right trim panel area. See KGIS ETM for more in-depth detail if necessary.

NOTE: If a circuit pin terminal connection replacement is required (identified using a pin tension tool gauge), please contact Techline by opening a Web Techline case for Pin terminal connection replacements. Four (4) Pin terminal connections (wire with terminal) will be shipped to your dealer. (Splice/soldering technique will be needed to properly complete the repair).

The procedure below will ensure completion of repairs:

Access right lower trim panel, and remove all necessary trim for access.
Record radio presets, and then disconnect negative battery terminal.
Locate connector EM61 (Passenger in-panel junction box), and then unplug connector. Remove the black locking cover on the connector.
Pull up the yellow locking tab using a small screwdriver or pick.
Locate pins 19, 20, 21 and 22 (Red/Black/White/Yellow) on the female side.
Remove pins from connector EM61 (Yellow/White/Black/Red).
Cut the wires to a reasonable length (stagger technique) to ensure that you have enough room to efficiently solder the wires in a place where pressure will not be applied on the solder points.
After installing replacement pins in connector EM61, splice pins 19, 20, 21, and 22 using proper soldering technique.
If all 4 (new splice pins) are the same color; take care so as not to get them crossed/mismatched.

NOTE: Be sure to use shrink wrap tubing on all soldered wires.
After the 4 wires have been soldered, wrap wiring harness with electrical tape to protect newly soldered points.
Reconnect EM61 to Joint connector ensuring locking tabs are secured. Reinstall trim in reverse order. Reconnect battery and Clear DTC's using GDS.
