Usage Features:

Remote Start Activation:
- 3x OEM Lock: Pressing the Lock button on the OEM remote three times consecutively will remote start the vehicle. Pressing it three times again can shut down the remote starter if the OEM remote remains active while the engine is running.
- RF System (with XL202): Connects to an optional XL202 RF system for remote control.
- SmartStart: Integrates with Directed SmartStart for control via a smartphone application, offering features like Lock/Arm, Unlock/Disarm, Remote Car Starter, Trunk Release, Panic, AUX Channels, GPS tracking, SmartSchedule, vehicle status, roadside assistance, and parked car finder.
Pit Stop/Idle Mode: Allows the vehicle to remain running while the driver exits with the key. Activated by putting the vehicle in Park and pressing the Remote Start button.
Vehicle Takeover: After remote start, the driver can enter the vehicle, insert the key, turn it to the ON position, depress the brake pedal, and put the car in gear to drive off.
Key2GO: Facilitates immobilizer bypass programming with only one key, by generating a duplicate of the original key's encryption via server interaction.
Module Programming:
- 2 Keys Required: Involves connecting harnesses, inserting and removing two different master keys in sequence.
- 1 Key Required (Key2GO): Involves connecting harnesses, inserting the key, turning ignition ON/OFF twice, then removing the module to submit a Key2GO request via computer.
- Convenience Only (Skip Transponder): Involves connecting harnesses, pressing the programming button five times, turning ignition ON, and then OFF.
LED Diagnostics: Provides visual feedback through LED flashes (solid red, green, orange, red & orange, red flashes) to indicate programming status, errors, active commands, and shutdown codes.

Maintenance Features:

Soft Reset: Erases only the programming steps performed, without affecting the flashed firmware and settings. Performed by connecting harnesses, pressing and holding the programming button, and releasing after the LED turns solid orange.
Hard Reset: Reverts the flashed firmware back to its default factory settings. This may require reconfiguring RFTD and D2D options. Performed by connecting harnesses, pressing and holding the programming button, and releasing after the LED flashes orange and red.
Troubleshooting: The manual provides detailed LED diagnostics and troubleshooting tables for module programming, error codes, active ground when running status, commands, shutdown codes, and RSR error codes, guiding installers through common issues.
Firmware Updates: The module can be updated via DirectLink or the Directechs Mobile app, ensuring access to the latest features and vehicle compatibilities.

Installation Considerations:

Intended for installation by a professional installer only to prevent damage to the vehicle's electrical system.
RSR installations are not compatible with manual transmission vehicles.
All connectors are displayed from the wire side, except for the OBDII diagnostic connector.
Specific wiring connections are detailed for the Data 14-pin blue connector (H1) and Output 12-pin red connector (H2), Input 10-pin black connector (H3), D2D 4-pin white connector (H4), and RF 2-pin white connector (H5).
SmartStart and XL202 modules must be connected in a specific order, and the DB3 module must be disconnected from power before connecting SmartStart to prevent damage.
SmartStart Revision A requires cutting the Brown or Blue loop, while Revision B requires connecting the Gray wire to ground.
XL202 requires using the D2D Crossover (XOVER) cable provided with XL202, not the one in the DB3 package.
