Warning! Safety first

following safety warnings must be observed at all times:

  • Due to the complexity of this system, installation of this product must only be performed by an authorized Directed dealer.
  • When properly installed, this system can start the vehicle via a command signal from the remote control. Therefore, never operate the system in an area that does not have adequate ventilation.

The following precautions are the sole responsibility of the user; however, authorized Directed dealers should:

  • Never use a test light or logic probe when installing this unit. Always use a multimeter.
  • Never operate the system in an enclosed or partially enclosed area without ventilation (such as a garage).
  • When parking in an enclosed or partially enclosed area or when having the vehicle serviced, the remote start system must be disabled using the installed toggle switch. It is the user’s sole responsibility to properly handle and keep out of reach from children all remote controls to ensure that the system does not unintentionally remote start the vehicle.
  • USER MUST INSTALL A CARBON MONOXIDE DETECTOR IN OR ABOUT THE LIVING AREA ADJACENT TO THE VEHICLE. ALL DOORS LEADING FROM ADJACENT LIVING AREAS TO THE ENCLOSED OR PARTIALLY ENCLOSED VEHICLE STORAGE AREA MUST REMAIN CLOSED AT ALL TIMES.

Use of this product in a manner contrary to its intended mode of operation may result in property damage, personal injury, or death. Except when performing the Safety Check outlined in this installation guide, (1) Never remotely start the vehicle with the vehicle in gear, and (2) Never remotely start the vehicle with the keys in the ignition. The user is responsible for having the neutral safety feature of the vehicle periodically checked, wherein the vehicle must not remotely start while the car is in gear.

This testing should be performed by an authorized Directed dealer in accordance with the Safety Check outlined in this product installation guide. If the vehicle starts in gear, cease remote start operation immediately and consult with the user to fix the problem immediately.

OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN GEAR IS CONTRARY TO ITS INTENDED MODE OF OPERATION. OPERATING THE REMOTE START SYSTEM UNDER THESE CONDITIONS MAY RESULT IN PROPERTY DAMAGE OR PERSONAL INJURY. IMMEDIATELY CEASE THE USE OF THE UNIT AND REPAIR OR DISCONNECT THE INSTALLED REMOTE START MODULE. DIRECTED WILL NOT BE HELD RESPONSIBLE OR PAY FOR INSTALLATION OR REINSTALLATION COSTS.

Remote starters for manual transmission pose significant risks if not properly installed and operated. When testing to ensure the installation is working properly, only remote start the vehicle in neutral gear, on a flat surface, and with a functional, fully engaged parking brake. Do not allow anyone to stand in front of or behind the vehicle. This product should not be installed in any convertible vehicles, soft or hard top with a manual transmission. Installation in such vehicles may pose certain risks.

Pre-installation and application warnings

Firmware notes: This section highlights important information for this specific firmware and will assist in pricing accordingly, as well as bringing awareness to any operational or vehicle limitations.

  • Important! RSR installations are NOT compatible with vehicles equipped with a manual transmission.
  • Remote Start Ready (RSR) is 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.
  • Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
  • Important! This firmware does NOT support Immobilizer bypass. One (1) programmed OEM key must be wired into the vehicle to complete the installation of a remote starter.
  • Refer to “Vehicle connections” following the wiring diagram.

  3. Release the programming button. The LED turns ON solid red.

Feature programming

To enter the 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 the 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 the 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 a 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.

Feature and option list

It is recommended to configure all the features and options listed below using the configuration tool found on the module flashing page at www.directechs.com. The web offers more options; however, manual configuration of the features is possible using the information on this page.
