Subject
2009 OPTIMA/RONDO WITH 2.4L AND DTC P2610
DESCRIPTION
Select 2009 model year vehicles are equipped with logic in the ECM to power-down the unit after 90 days of storage time. The diagnosis DTC P2610 may lead you to believe there is an internal error in the PCM. However extended vehicle storage will cause this DTC; once the ignition key is turned OFF the timer starts and will store a pending DTC after 45.5 days are reached and at 90 days the MIL will turn ON.
This will not necessitate PCM replacement. To repair this concern, disconnect the negative battery cable for 10 seconds and reconnect the battery cable or remove the 10 amp ECU fuse in the engine compartment.
To prevent this from happening during long-term storage times, start the engine every 30 days and check condition of battery per Kia warranty policy.
Storage Days:
45.5 days = P2610 Pending code
90 Days = P2610 Malfunction Indicator Lamp On
