NOTE:
This TSB applies if the vehicle ROM ID is listed in the PREVIOUS column of the ROM ID Table below. The ROM ID in the NEW column was the
latest available ROM ID at the date of this TSB publication, however, you may select a later event number if one is shown in the GDS ECM update
list, even if it describes another issue. This would generate a more recent ROM ID than shown below, but would also include the update from this
TSB.
GDS SYSTEM AND ECM UPDATE PRECAUTIONS:
CAUTION:
Please verify the following items before performing the ECM update:
^
Make sure the vehicle's battery has reasonable charge. If the vehicle has been in storage, run the engine to ensure an adequate battery charge state
for reliable update results. The ECM Update procedure contains a check to verify 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 in the lower right tray icons has 50% or more charge (half bar on the battery symbol). Charge the
laptop battery with the AC adaptor cable if the charge is less than 50%.
^
Turn off all lamps (do not leave head lamp switch in auto mode) and all accessories (including heater, NC, 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.
NOTE:
Make sure you have performed the most recent GDS and VCI Internet Updates to ensure you have the latest available ECM Update events.
