Introduction
DB3 is an all-in-one door lock and override module. This guide supports the installation of a DB3 in Remote
Start Ready (RSR) mode. This solution may offer up to three (3) configuration options to control your system: 3x
OEM Lock Remote Start Activation (if applicable, refer to the “Vehicle function compatibilities” below), RF System
or SmartStart (all sold separately).
Warning!
This module can only be flashed and configured using DirectLink at www.directechs.com or using the Directechs
Mobile application for smartphones. Refer to “Connecting the module” for more information.

well as bringing awareness to any operational or vehicle limitations.

Firmware notes
Remote Start Ready (RSR): A function that enables the interface module to remote start the vehicle completely on its own.
Consequently, there is no need for an aftermarket or an OEM remote starter in order to start the vehicle from a distance.
SmartStart Compatible: SmartStart is equipped with D2D, which means it can be connected to an interface module and used in
Remote Start Ready (RSR) mode without the use of a remote starter. See "Module programming" for more information.
Manual Transmission: RSR installations are not compatible with vehicles equipped with a manual transmission.
Visual Confirmations: Are made via the hazard lights instead of the parking lights. Therefore, shutdown error flashes do not apply.
Climate Controls: Audi climate controls are key memory sensitive, meaning the last key used to operate the vehicle will determine the
setting for the climate controls. In order to make changes to environment control settings, the following procedure is necessary:
• Remote start the vehicle.
• Make your climate control adjustments, ensuring not to use the AUTO mode on the control head as this makes the Audi adjust its
HVAC settings based on external factors such as engine temperature.
• When the adjustments are complete, turn off the vehicle starter, either by remote or footbrake. This will ensure the climate controls
function as the customer desires them too.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
Refer to the "Vehicle connections" following the installation diagram.
Footnotes
[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory hood pin or if
not supported in data.
[2] Key Release circuits: There are two possible types of Key Release circuits. Perform the Key Release Voltage Test explained in
the wiring diagram to determine which Key Release installation Type is required. For Key Wrap instructions, refer to "Immobilizer
Interface."
[3] Key Wrap: For Key Wrap instructions, refer to "Immobilizer Interface".

Connecting the module
Important!
Make all the required connections to the vehicle, as described in this guide, and double check to ensure everything is correct prior
to moving onto programming.
Note: Before connecting either the XL202 or SmartStart module to DB3, it is important to ensure that the proper feature and
function programming is selected using DirectLink (version 4.5 or higher). Visit www.directechs.com to download the latest version
of the application.
Warning! To take advantage of advanced features, you must use DirectLink 4.5 (and higher) or the Directechs Mobile application.
Flashing a module using your computer:
1. Connect the interface module to your computer using the XKLoader2.
2. Go to www.directechs.com using Internet Explorer, and select the Flash Module button.
3. Follow the instructions to select your vehicle, installation type, and configure your options.
4. Once you have configured the firmware options, click on the FLASH button.
Flashing a module using your smartphone or tablet:
1. Connect the interface module to your XKLoader3.
2. Launch the Directechs Mobile app on your smartphone or tablet.
3. Select FLASH YOUR MODULE and follow the on screen instructions.
When the flashing operation is successful, you can proceed with the instructions below.
SmartStart installation
The DB3 module must be disconnected from any power source before SmartStart can
be connected to it. Failing to do so could damage DB3.
1. To ensure that the D2D communication between SmartStart and DB3 works properly,
connect the Gray wire to a ground source (Rev B SmartStart), and cut the Brown or
Blue loop (Rev A SmartStart).
2. Do NOT connect the 2-pin harness (on SmartStart). Power and ground will be
provided by the DB3 D2D connector.
3. Connect SmartStart to DB3 using the D2D port.

LED Description Troubleshooting
Flashes red x 1 CAN2 not detected.
Check the CAN2 Orange/Green and Orange/Brown wire connections. Wake up the data bus
by turning the ignition on and try again. If your installation does not require this connection, skip
this step by pressing the programming button 5 times.
Flashes red x 1 J1850 not detected. Check the J1850 wire connection. Wake up the data bus by turning the ignition on and try
again.
Flashes red x 2 CAN1 not detected.

Feature programming
To enter feature programming routine:
1. Turn the ignition ON, then OFF.
2. Within 5 seconds, press and hold the programming button until the LED turns ON orange (after 3 seconds).
3. Release the Programming button.
4. The LED will flash green once slowly to indicate the feature number is 1. After a short delay, the LED flashes red rapidly to
indicate the current option of feature 1 (e.g. 1 x green followed by 1 x red indicates feature 1 is set to option 1). The flashing
sequence will repeat until a new command is entered.
Changing feature options:
1. Press the lock/arm or unlock/disarm button on aftermarket transmitter to change the option of the selected feature. When
installing the DB3 in RSR using 3x OEM Lock Remote Start Activation only, there is no aftermarket transmitter on which to press
lock/unlock to change the options of the selected feature. Tapping the green or blue lock/unlock wires on the black 10-pin
harness to ground will change the option for the selected feature.
2. The LED flashes red rapidly the number of times equal to the current option number. After a short delay, the LED flashes green
slowly the number of times to indicate the current feature. The flashing sequence will repeat until a new command is entered.
Accessing another feature:
1. Press and release the programming button a number of times to advance from the current feature to the next desired feature.
2. The LED flashes green slowly the number of times equal to the feature number. After a short delay, the LED flashes red rapidly
to indicate the current option of the current feature. The flashing sequence will repeat until a new command is entered.
When the maximum number of features or options is reached, the LED will start flashing again from the first feature or option.
Exiting feature programming:
To exit feature programming, press and hold the programming button for 3 seconds or ensure there is no activity on the interface
for 30 seconds. The LED will turn ON orange for 2 seconds to confirm the end of the programming sequence.
