This bulletin provides information related to an ECM software update of some Genesis Coupe 2.0L vehicles to address either of the following conditions:
^ Malfunction indicator lamp illuminated with DIG P0605 (Internal Control Module ROM Error) stored in the ECM. Vehicle may have been operating in the reduced power limp home mode.
^ Slow RPM drop when releasing the throttle during gear shifts or on deceleration from high engine speed
APPLICABLE VEHICLES:
Model: 2010 GENESIS COUPE (BK) 2.0L vehicles.
Affected vehicle production date range: Start of Production - July 10, 2009
NOTE:
To verify the vehicle is affected, check the version of the vehicle's control unit ROM ID with reference to the ROM ID Information Table before attempting to update the control unit software.
ROM ID INFORMATION TABLE:
^ After the ECM UPDATE, clear any DTC(s) from the control units which communicate with each other by CAN-bus, such as ESC, ACU, TPMS and the Smart key system. (The ECM is an immobilizer type if the vehicle has the Smart key system.)
SERVICE PROCEDURE:
GDS SYSTEM AND ECM UPDATE PRECAUTIONS:
CAUTION:
Please assure the following prior to the ECM update:
^ Make sure the vehicle's battery has reasonable charge. If the vehicle has been in storage, run the engine to assure an adequate battery state of charge for reliable update results. The ECM Update procedure contains a check to assure that battery voltage is above 12 volts to allow the procedure to occur.
^ The USB cable must be used for ECM Update between the GDS and VCI the procedure will not work in VCI wireless mode.
^ Make sure the GDS laptop battery indicator icon in the lower right tray has 20% or more charge remaining. If necessary, charge the laptop battery with the AC adaptor cable. We recommend GDS being attached to A/C during reprograms.
^ Turn off all lamps (do not leave head lamp switch in auto mode) and all accessories (including heater, A/C, blower, radio, seat warmer, defroster, etc.) to prevent battery discharge during the update.
^ Perform update with the ignition switch in the ON position.
^ Be careful not to disconnect any cables connected to the vehicle or scan tool during the update.
^ Do not start the engine during update.
^ Do not turn off the ignition switch during update.
^ Make sure the GDS system has the latest internet update.
