GENERAL INFORMATION AND DIAGNOSIS
FOR SMART KEY FOB SYSTEMS AND START/STOP BUTTONS
This bulletin provides information related to the Smart Key Systems on vehicles equipped with
A/T (automatic transaxle) and Start/Stop Buttons (SSB). On these types of vehicles, the engine
will only start if the right conditions are met and in combination with the inhibitor switch signal,
the stop lamp switch signal and the shift lever position. In most instances, when attempting to
start the engine without the brake pedal being depressed, the engine will not start as no signal
is being received from the stop lamp switch. Frequently, stop lamp switch replacements are
performed in the field without proper diagnosis, therefore, in order to prevent unnecessary
replacement of stop lamp switch and other components, refer to the basic operation of the
Start/Stop Button, Smart Key Fob and the Shift Lock system, as outlined below.
 NOTICE
The Smart Key Fob may fail to operate correctly when in close proximity to other
devices (i.e. cellphones, etc.) which use Radio Frequency (RF) and Low Frequency
(LF) for transmission. Always keep the Smart Key FOB away from possible sources
of radio interference.

Smart key programming procedure
1.
Connect the power supply cable to the GDS.
 NOTICE
If attempting to perform the upgrade with the power supply cable disconnected
from the GDS, be sure to check that the GDS is fully charged before upgrade. If
the GDS is not fully charged, failure to perform the upgrade may occur. Therefore,
it is strongly recommended that the power supply connector be connected to the
GDS.
2.
Connect the USB cable between the VCI and the GDS.
 NOTICE
When performing the ECM upgrade using the GDS, wireless communication
between the VCI and GDS is not available. Therefore, be sure to connect the USB
cable between the VCI and the GDS.
3.
Connect the Main 16-pin DLC cable (GHDM – 241000) to the VCI.
4.
Connect the Main 16-pin DLC cable
(GHDM – 241000) to the OBD-II
connector, located under the driver's
side of the instrument panel.
5.
Select ENGINE and click OK.

Start/Stop Button Basic Operation
1.
Power ON / Engine ON

To start the engine, press the Start/Stop Button with the Smart Key Fob in the cabin,
while depressing the brake pedal and with the shift lever in ‘P’ or ‘N’.
(Hybrid vehicles : ‘P’ only)

Whenever the Start/Stop Button is pressed with the Smart Key Fob in the cabin
without depressing the brake pedal, the Start/Stop button LED status will be changed
in the following sequence: OFF → ACC (Orange) → IGN ON (Green) → OFF.

2.
Power OFF / Engine OFF
 Shut the Engine OFF only when the vehicle is stopped completely. However, the
power will completely cut off only in ‘P’ to prevent the steering column from locking.

If the brake fuse is blown or the stop lamp switch is inoperative, press the Start/Stop
Button for 10 seconds, or more, to start the engine.
Depressing the Brake Pedal at Start-up
1.
Be sure to press the SSB after fully depressing the brake pedal to operate the stop lamp
switch. The amount of brake pedal effort may vary depending on the amount of vacuum
present in the brake booster chamber. If the vacuum is exhausted, more brake pedal
effort is needed to operate the stop lamp switch. NOTE: The engine will not start if the
SSB is pressed prior to stop lamp switch operation.
