Installing a Viper remote start system in your Silverado can significantly enhance convenience and security, allowing you to start your truck remotely and pre-heat or pre-cool the cabin. However, some Silverado models have factory anti-theft systems that might interfere with aftermarket remote starters. This guide focuses on installing a Viper remote start while bypassing the factory disable, offering a detailed walkthrough for a successful and secure installation. This guide assumes a basic understanding of automotive electronics and wiring. If you're uncomfortable working with car electronics, it's best to seek professional installation.
Understanding Factory Disables and Bypassing Them
Many modern vehicles, including Silverados, employ various security measures to prevent unauthorized starting. These can range from simple immobilizers requiring a specific key to more sophisticated systems that monitor various vehicle sensors. A Viper remote starter installation often requires bypassing these systems to ensure seamless functionality. This isn't about disabling your factory security entirely, but rather creating a pathway for the remote starter to communicate with the vehicle's systems without triggering the anti-theft mechanisms.
What Happens When the Factory Disable Intervenes?
When a factory disable is active and not properly bypassed during a remote start installation, you might experience issues such as:
- Remote start failure: The truck simply won't start using the remote.
- Intermittent operation: The remote start might work sometimes and fail at other times.
- Security light activation: Your truck's security light might illuminate, indicating a problem.
- Alarm triggering: The vehicle alarm may activate unexpectedly.
How to Install a Viper Remote Start in Your Silverado Without Disabling Security Features
Note: Specific wiring diagrams and bypass modules vary depending on your Silverado's year and model. Always consult your Viper remote start kit's instructions and a wiring diagram specific to your vehicle. Incorrect wiring can damage your vehicle's electrical system.
The installation process generally involves these key steps:
-
Gather Your Tools and Materials: You'll need the Viper remote start kit, wiring harness, bypass module (if required), wire strippers, crimpers, soldering iron (optional), electrical tape, zip ties, and a multimeter.
-
Disconnect the Battery: Always disconnect the negative battery terminal before starting any electrical work on your vehicle. This is crucial for safety.
-
Locate the Necessary Wiring Connections: This is the most critical and potentially challenging step. You'll need to locate the wires for the ignition, starter, accessory power, and potentially others depending on the Viper system’s features (e.g., door lock control). Use your vehicle's wiring diagram and the Viper installation manual to correctly identify these wires.
-
Install the Bypass Module (If Necessary): Many Viper systems require a bypass module to communicate with your vehicle's immobilizer system. Follow the instructions provided with the bypass module and connect it according to the wiring diagram. This module typically intercepts and replicates the signals necessary for the vehicle to start without triggering the security system.
-
Connect the Viper Wiring Harness: Carefully connect the Viper wiring harness to the appropriate wires in your Silverado, following the wiring diagram provided in your Viper kit and vehicle's wiring diagram. Double and triple check all connections to ensure accuracy.
-
Secure all Wiring: Once all connections are made, neatly secure the wires using zip ties and electrical tape. Avoid any loose wires that could potentially short or create problems down the road.
-
Program the Remote: Follow the Viper system's instructions to program your new remotes. This often involves a series of button presses on the remote and the vehicle's ignition switch.
-
Test the System: Reconnect the battery and test the remote start functionality. Make sure the truck starts and runs smoothly without triggering the alarm or security lights.
-
Reconnect the Battery: Once everything works correctly, reconnect the negative battery terminal.
Troubleshooting Common Installation Issues
- Remote start doesn't work: Double-check all wiring connections, ensure the bypass module is correctly installed and programmed, and verify the correct programming of the remote.
- Alarm triggers: This often indicates an incorrect wiring connection or a problem with the bypass module. Re-check your wiring carefully.
- Intermittent operation: This could be due to loose wiring, a faulty connection, or a problem with the bypass module.
Frequently Asked Questions (FAQs)
Will installing a Viper remote start void my warranty?
Modifying your vehicle's electrical system might void certain aspects of your warranty. Check your warranty terms and conditions, and consider discussing the installation with your dealer beforehand. A professional installation can sometimes help mitigate warranty concerns.
What type of Viper remote start system should I get for my Silverado?
The best Viper system will depend on your specific Silverado model and your desired features. Consider factors like range, additional features (like trunk release), and compatibility. Consult Viper's website or a qualified installer for recommendations.
Can I install this myself, or should I hire a professional?
While technically possible to install a Viper remote start yourself, it requires electrical expertise and attention to detail. If you're unsure, hiring a professional installer is recommended to prevent damage to your vehicle.
How much does it typically cost to have a Viper remote start professionally installed?
The cost of professional installation varies depending on location, the complexity of the system, and the installer's labor rates. It's advisable to get quotes from several installers before making a decision.
Remember, always refer to the specific instructions provided with your Viper remote start kit and your vehicle's wiring diagram. Safety should be your top priority during the installation process. If you're unsure about any step, seek professional help.
