SUBJECT:
2.7L (MU) OPTIMA (MG) AND RONDO (UN) P0110 REPROGRAM
This service bulletin provides information related to the powertrain control module (PCM) upgrade for all 2.7L (Mu) powertrain control modules. This
PCM reprogramming is applicable to all 2006.5 - 2007 Optima (MG) models produced between 12/09/2005 - 06/05/2007 and 2007 Rondo (UN) models
produced between 09/06/2006 - 07/05/2007. Some vehicles with a 2.7L engine may experience a malfunction indicator lamp (MIL) illumination with
DTC P0110 (Intake Air Temperature Circuit Malfunction), even though no actual circuit malfunction exists. To correct this condition, the PCM should
be reprogrammed using the GDS download as described in this bulletin before attempting to repair this concern.
Note:
Global Diagnostic System (GDS) users should access the "Notice" function from the GDS Main Screen for instructions regarding ECU upgrade
events.
*NOTICE:
^
A fully charged battery is necessary before PCM upgrade can take place. DO NOT connect a battery charger to the vehicle during PCM upgrade.
Make sure the blower motor is "OFF" during PCM upgrade.
^
All PCM upgrades must be done with the ignition key in the "ON" position.
^
Be careful not to disconnect any cables connected to the vehicle or GDS during the PCM upgrade procedure.
^
DO NOT start the engine during PCM upgrade.
^
DO NOT turn the ignition key "OFF" or interrupt the power supply during PCM upgrade.
^
When the PCM upgrade is completed, turn the ignition key "OFF" and wait 20 seconds before starting the engine.
^
ONLY use approved PCM upgrade software designated for the correct model, year and engine size. Failure to do so may create other driveability
issues due to the use of the incorrect PCM calibration.
