Firmware notes
OEM Remote Starter: Before programming your module, you must first check if your vehicle is equipped with an OEM remote
starter and disable it. If the vehicle is equipped with an OEM remote starter, whether Active or Inactive, it MUST be temporarily
disabled or permanently disconnected depending on the vehicle. Please refer to the “OEM remote starter information” section of the
guide for additional details. Also, to remote start the engine, all doors must be closed.
Note: In some cases, the module will program to the vehicle even if equipped with an OEM starter, but will prevent the aftermarket
remote start from functioning properly.
Remote Start: All doors must be closed and locked to remote start the vehicle.
Motorized Hatch: If available, the Motorized Hatch feature needs to be enabled using the configuration tool found on the module
flashing page on www.directechs.com.
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] Tach wire: Optional connection required on some remote starters, which do not support a tach signal in D2D.
[3] Pit Stop/Idle mode: This connection is only required for Pit Stop/Idle mode in manual transmission vehicles or Ready mode for
vehicles with hybrid engines.
[4] SLP: See "Locating Steering Lock Connector in Vehicle" in Vehicle wiring reference chart.

OEM remote starter information
If the vehicle has an active OEM remote starter, it will program into convenience only (no immobilizer bypass). This is is to allow aftermarket
security to be installed while keeping the factory remote starter active. If you wish for the interface to control the remote start sequence, perform
one of the following action:
How to determine if a vehicle is equipped with an OEM remote starter?
If the vehicle is equipped with an Add-On Lexus/Toyota OEM remote starter: Some Lexus/Toyota vehicles may have an Add-
On OEM remote starter. If the OEM unit is installed, whether Active or Inactive, it MUST be permanently disconnected, as both modules cannot
coexist. Refer to "Physical OEM remote start locations" in the chart below and always physically inspect and disconnect any OEM remote starter
before programming any Directed products.

If the vehicle is equipped with a BCM Enabled Lexus/Toyota OEM remote starter: The vehicle does not have a physical remote
starter and only one module can be programed at a time. In this case, temporarily disable the OEM remote start system using the following
process:
1. Remove the fuse powering the OEM Remote Starter. See "OEM remote start fuse location"
2. Perform a "Soft reset" or "Hard reset".
3. Perform the "Module programming".
4. After programming is successful, re-insert the fuse powering the OEM Remote Starter.

Module programming
Refer to “LED diagnostics and troubleshooting” for more information and for troubleshooting purposes.
IMPORTANT!Before programming your module, you must first check if your vehicle is equipped with an OEM remote starter
and disable it. If the vehicle is equipped with an OEM remote starter, whether Active or Inactive, it must be temporarily
disabled or permanently disconnected depending on the vehicle. Please refer to the "OEM remote starter information" section
of the guide for additional details.
Note:In some cases, the module will program to the vehicle even if equipped with an OEM starter, but will prevent the
aftermarket remote start from functioning properly.
For Convenience-Only programming, see next section.
1Ensure vehicle is in a safe location, and cannot move forward during programming. For vehicles
equipped with a manual transmission, make sure the gearshift lever is in the neutral position.
2
The harnesses must be connected in this exact order:

Connect the 14-pin.1.
Connect the 12-pin.2.
Connect the 10-pin.3.
When the LED turns on solid red, proceed with the next step.
3Press the Push-to-Start (PTS) button twice (2x) to turn the ignition ON.
The LED turns on solid orange.
4
Press the PTS button once more to turn the ignition OFF, then twice to turn it back ON.
The LED turns ON solid green for 3 seconds then shuts OFF.
If the module flashes orange, your vehicle is equipped with a factory remote starter. See "Pre-
installation and application warnings".
5Press the PTS button once more to turn the ignition OFF.
You have successfully completed the module programming sequence.

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.
