2012 Kia Optima L4-2.4LFACTORY OEM SERVICE PROCEDURE
Remote Starting System - Won't Work On First Attempt
NUMBER: 034
GROUP: Electrical
DATE: January 2012
MODEL: 2011/12MY Sorento (XM), Optima (TF/QF)
SUBJECT: REMOTE START SYSTEM DNA MODULE SOFTWARE UPGRADE
This bulletin provides information relating to some 20111/2012MY Sorento (XM) and Optima (TF/QF) vehicles that are equipped with the remote start option (Sorento P/N U8560 1U001/2 and Optima P/N 2T056 ADU00) as supplied from Job #1 to October 6, 2011. In some of these vehicles the Remote Start System may not always start the vehicle on the first attempt and when the start attempt fails the security system gets triggered. Once the security system is disarmed/unlocked a second attempt is required to start the vehicle. This bulletin provides a repair for this concern by replacing the DNA module in the Remote Start System with an updated version. (Remote Start Systems installed after October 6, 2011 use a new kit [Sorento P/N U8560 1U003 and Optima P/N 2T056 ADU01] that already incorporates this update).
Service Procedure:
1. Refer to the vehicle specific "Remote Engine Start" installation instructions to remove and isolate the negative battery cable from the battery and to access the Remote Start Control Module. Observe the DNA card service part number listed on the case top. If the part number is U8562 00011 for a Sorento or U8562 00012 for an Optima the DNA card will need to be replaced with updated software to correct the concern.
