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.
