Portable OBD Port

Portable OBD Port with wires allows to connect GAT Coder to power and LAN internet

router.

Power requirements GAT Coder has internal battery which allows device to work autonomously for 30-45

minutes. Battery status is indicated in the top info line on LCD display. Whenever

battery level is under 50% connect GAT Coder to vehicle’s OBD port for charging.

Alternatively Portable OBD Port can be used for charging.

GAT Coder requires 12V-13.8V and at least 2A for charging of the internal battery.

Should simultaneous operation and charging of the GAT coder be required, the power

supply with at least 3.5A current and 12V-13.8V will be needed. Whenever GAT Coder is

connected to vehicle’s OBD port it can be both charged and operated simultaneously.

Device connection and start-up To turn ON the GAT Coder press Power button (top right button) shortly.

To turn OFF the GAT Coder press and hold Power button for at least 3 seconds.

After GAT Coder is turned “ON” it takes about 30-45 seconds for it to boot up. As soon

as boot process is finished main menu of GAT coder will appear on display.



Two different types of connection are supported by GAT Coder – Local wired connection

(CAN Bus Local) and Remote network connection (ENET or ICOM).

Local wired connection via CAN Bus – most frequently used connection whenever device is

connected via the OBD cable to a vehicle. This connection is always selected by default.

Simply connect OBD cable to vehicle and to GAT Coder, make sure that vehicle ignition

is ON and press CONNECT button on LCD of GAT Coder.

Device will start connection procedure with the vehicle. Progress bar at the bottom right

will show the percentage of completion of the process. All information during

connection will be shown on the primary information display part at the right side of

LCD display.



Should ENET or ICOM remote connection be required the device will need to be connected

to internet via local LAN (part of the OBD cable) or WiFi dongle. GAT Coder supports

connection over internet via port 6801, 6802 and 50160 to remotely connected vehicles.

At the vehicle side appropriate port should be opened and forwarded to the vehicle’s IP.

Choose desired connection (ICOM or ENET), type in IP address of the remote internet

host with vehicle’s port forwarded and type in port (default 6801). Press “Connect”

button once all information is entered. Device will attempt to connect remotely to the

vehicle. Once connection is established, vehicle information will appear in the Primary

Information Display.

If for any reason connection cannot be established the “Connect” button will become

RED and error information will be shown in Primary Information Display.

When connection is successfully established, the “Connect” button will change to

“Disconnect” and will become GREEN.

If “Disconnect” button is pressed, the current connection will be cancelled.

Menu Navigation On-screen menu has a tab structure. Each tab has a name associated with it. When a

particular tab is selected, the new tab page will be opened on display.



From left to right, the tabs are as follows:

Connect – Connectivity tasks.

SWID – Reading of the current FSC statuses of head unit

FSC – FSC code importation

Cert – Certificate importation

eFSC – Easy FSC (quick FSC) importation

FDL – FDL Coding of the ECU using scripts

ASAP – Assistance portal for FSC and scripts downloading and management

Tools – Additional tools for use with vehicle’s ECUs

DTC – Basic vehicle diagnostic and DTC code removal

Settings – Configuration tab

Vehicle SWT tasks (FSC, Certificates, eFSC)

SWID tab allows GAT Coder to read out current statuses of all FSC codes loaded in head

unit.



Pressing the button “Read” or “Re-Read” will trigger GAT to pull up current statuses of

head unit’s SWT and show them on the Information Display. SWID for each FSC as well

as its status and status of its Certificate will be shown.

In addition statuses of Root, Signatures and Software signatures certificates will be

shown on the Information Display together with head unit variant, activation type and

head unit bootloader code.

Additional technical information from head unit will be shown on Information Display.

FSC tab allows read, check and write of FSC codes into head unit.

Each available FSC code can be selected with the ‘radio button’ selector type. Selected

FSC code can be read and shown on the Information Display. FSC code can then be

saved on local storage inside of GAT by pressing ‘Save’ button.

When different FSC code needs to be loaded instead of currently selected one, the new

FSC code will need to be loaded up to Information Display first. This can be done by

pressing ‘Load’ button, selecting appropriate FSC code from local storage and loading it



onto to Information Display. Then the ‘Check’ button should be pressed to verify

currently loaded FSC code. Finally ‘Write’ button should be pressed to write FSC code

into head unit. This operation can be repeated for each individual FSC code, if needed.

FSC VIN of the head unit can be changed with ‘VIN Write’ button. VIN number (last 7

digits) must be entered into specific field to the left of the button.

Each time FSC code is read or loaded, information about FSC code will appear at the top

left corner. FSC Date will show original FSC code creation date (year/month/date); FSC

Type will show the creator (Dealer or Factory) and FSC VIN will show the VIN number of

the FSC code.

Cert tab allows read, check and write of the FSC codes certificates to head unit.

Cert tab is very similar to the FSC tab in the way it functions.

Each time certificate is read or loaded, the certificate status will appear at the top left

corner. Root will show the status of Root certificate (Accepted or Rejected); Sigs will

show the status of signature certificate (Accepted or Rejected) and Soft will show the

status of software signatures certificates (Accepted or Rejected).



Each certificate for FSC can be individually selected, read and written. Usually FSC

certificates are imported by the manufacturer and no further changes of these

certificates are required.

eFSC tab allows quick and direct FSC code importation without intermediate verification

procedure. This procedure is normally used when all FSC codes of head unit need to be

replaced by another set of FSC codes. FSC VIN of head unit will be automatically

changed to match the VIN of the newly-loaded FSC set.

After pressing ‘Import’ button, a pop-up screen will appear on the display where you

will be able to select an FSC code file from the internal GAT storage for importation.

As soon as selection is confirmed, GAT Coder will automatically import and verify the

FSC code. Result will be shown on Information Display. This procedure should be

repeated for each of FSC code in new set.

In case when certificate for a selected FSC code should also be replaced, the ‘Certificate’

checkbox should be checked before the ‘Import’ button is pressed.

Primary advantage of eFSC tab over FSC tab is simplicity of FSC code importation

procedure, which does not require any intermediate FSC code verification. Also the VIN

number for the FSC code is changed in the head unit automatically. Procedure is very

simple and can be described as: ‘select from local storage -> directly load to head unit’.



FDL Coding

FDL tab allows FDL coding for desired ECU with the use of pre-defined coding scripts.

Each script contains a list of commands for ECU configuration.

List of ECUs available for coding is shown at the left side of the screen. Once the ECU

from the list is selected, current software version of the ECU will appear on the

Information Display.

FDL Coding Procedure



1. Desired FDL script should be loaded from the local storage by pressing ‘Load Script’

button. After pressing “Load Script” button, a pop-up screen will appear on the

display where you will be able to select Desired FDL script.

It is important to pay attention to naming of the scripts. Usually script name starts

with vehicle series name following by ECU name and then following by actual script

name. For example script: F_CIC_VideoInMotion will activate Video in Motion

feature in CIC head unit in F series BMW only. You should always load appropriate

script for vehicle / head unit which is currently connected.

2. Select desired FDL script from local storage in the pop-up window and press OK.

Script will be loaded to the GAT Coder and button ‘Read FDL’ will become active. By

pressing this button the selected script will be parsed and current configuration of

ECU will be read and temporary stored by GAT coder.

Note that ECU for FDL coding is selected automatically by GAT Coder based on the

selected script.

After script verification is completed the “Apply Script” button will become active.

By pressing ‘Apply Script’ button the loaded script will be executed and will change

the ECU configuration temporary stored in GAT. Upon completion the button ‘Write

FDL’ will become active.



By pressing ‘Write FDL’ button GAT Coder will start coding process of selected ECU in

accordance with ECU’s configuration temporary stored in GAT. Once coding is

completed confirmation message will be shown.

In case of error during the coding the ‘Restore’ button will become active. Pressing

‘Restore’ button will restore the ECU back to its original configuration.

Warning! It is very important not to interrupt FDL coding process until it is completed.

Interruption or disconnection during FDL coding will cause damage to ECU and may

require its replacement or special low level re-coding/re-flashing.

ASAP

ASAP tab allows user to download FDL scripts, which were created in GAT Online system

as well as to download FSC codes and manage local FDL scripts and FSCs.

Button ‘Get’ will list all FDL scripts created at GAT online system by the user and

available for download. Select desired FDL script from the list at the left and press

‘Download’ button to copy it to local GAT storage.



‘Local FDL’ button will list all FDL scripts stored in GAT. To delete FDL script, select FDL

script from the list on the left, and press ‘Delete FDL’ button.

‘Local FSC’ button lists all FSC codes stored in GAT.

‘Get FSC’ button downloads FSC code for desired VIN number entered in VIN field.

Please note that the quantity of FSC codes you can download is limited by your

particular GAT device plan.

Tools

Tools tab contains additional service commands.

Direct commander sends some pre-defined commands directly to ECU.

ECU can be selected from drop down menu. Each ECU available in drop down menu is

shown in hex address representation and common name. Command can be selected



from the drop down menu. Button ‘ECU Direct’ will send selected command to selected

ECU. The result of command execution will appear in information display.

‘Ping ECU’ button sends standard ‘ping ident’ request to selected in drop down menu

ECU. Result of ping will appear in the information display

DTC

DTC tab is used for basic diagnostic trouble codes read and erase.

By pressing ‘Read DTC’ button GAT Coder will start reading all DTC trouble codes from

each ECU. This process can take a few minutes and depends on the quantity of DTC

codes stored in the system. Once DTC codes are read by GAT it is possible to view DTC

error codes on the Information Display by using scroll on the right side of the

Information Display. Each DTC error code will include its manufacturer’s standard

number and basic description (if available in the data base). In addition, mileage at

which DTC error occurred will also be shown (if available). All DTC error information

obtained from the vehicle will be stored on the local storage of GAT for further review, if

needed.



By pressing ‘Clear DTC’ button all DTC error codes stored in the vehicle for each ECU will

be deleted. DTC light in KOMBI cluster will be turned off.
