Setup and Installation
The Viper 3103V 1-Way Security System requires professional installation. Due to the complexity of vehicle electrical systems and the critical nature of security features, it is highly recommended that installation be performed by a certified Viper dealer or an experienced automotive electronics technician. Improper installation can lead to system malfunction, vehicle damage, or voiding of the product warranty.
Key Installation Steps (Overview for Technician)
- Mounting the Main Control Unit: Securely mount the alarm brain in a hidden, dry location within the vehicle.
- Wiring Connections: Connect power, ground, ignition, and accessory wires according to the detailed wiring diagram provided with the product.
- Siren Installation: Mount the siren in the engine bay, away from heat and water, with the horn facing downwards to prevent water collection.
- Impact Sensor Placement: Install the impact sensor on a solid surface within the vehicle, adjusting sensitivity as needed after installation.
- Starter Interrupt: Integrate the starter interrupt relay into the vehicle's starter circuit to prevent unauthorized engine starting.
- Door Lock/Unlock Integration: Connect to the vehicle's central locking system for keyless entry functionality.
- Parking Light Flashing: Connect to the vehicle's parking light circuit for visual confirmation of system status.
Operating Instructions
Your Viper 3103V system is operated using the two 1-way remote controls provided. Familiarize yourself with the buttons and their functions.

Image: The two 1-way remote controls for the Viper 3103V security system. Each remote features buttons for arm/disarm (lock/unlock icon), auxiliary functions (star/AUX), and a panic/car locator button.
Arming the Security System (Locking Doors)
Press the Lock/Arm button (usually depicted with a padlock icon) on your remote control. The system will arm, and your vehicle's doors will lock. The parking lights will flash once, and the siren will chirp once to confirm arming.
Disarming the Security System (Unlocking Doors)
Press the Unlock/Disarm button (usually depicted with an unlocked padlock icon) on your remote control. The system will disarm, and your vehicle's doors will unlock. The parking lights will flash twice, and the siren will chirp twice to confirm disarming.
Panic Feature / Car Locator
To activate the panic feature or locate your vehicle in a crowded parking lot, press and hold the Panic/Car Locator button (often marked with a speaker or car icon, or combined with another button) on your remote control for approximately 3 seconds. The siren will sound, and the parking lights will flash. To turn off the panic mode, press any button on the remote control.
Impact Sensor
The integrated impact sensor detects impacts to your vehicle. A light impact will trigger a warning chirp from the siren. A heavier impact will trigger the full alarm, causing the siren to sound continuously and the parking lights to flash. The sensitivity of the impact sensor can be adjusted by your installer.
Starter Interrupt
When the security system is armed, the starter interrupt feature prevents the vehicle's engine from starting, providing an additional layer of theft protection.
Maintenance
The Viper 3103V security system is designed for minimal maintenance.
- Remote Control Batteries: Replace the batteries in your remote controls when the range decreases significantly or the LED indicator on the remote becomes dim. Refer to the remote control's specific instructions for battery type and replacement procedure.
- Cleaning: Keep the remote controls clean and dry. Avoid exposing the main control unit or siren to excessive moisture or extreme temperatures.
- System Checks: Periodically test the system's arming, disarming, and panic functions to ensure proper operation.
