For Dodge Charger Hellcat owners looking to unleash the full potential of their ride with HP Tuners, understanding the Smart Access Cable is crucial. This guide provides a step-by-step walkthrough on how to install the Smart Access Cable in your Hellcat Charger, specifically addressing the security module location which differs from Challenger models. If you’ve been searching for clear instructions to bypass the security module for tuning your high-performance Charger, you’re in the right place.
Before beginning, it’s important to understand why this cable is necessary. For 2018 and newer Charger and Challenger Hellcats, the Smart Access Cable acts as a permanent security bypass. This bypass is essential for reading your factory PCM/TCM files, applying tune modifications, and flashing new tunes using HP Tuners VCM Suite. Without it, accessing and modifying your Hellcat Charger’s performance parameters simply isn’t possible.
Step-by-Step Hellcat Charger Smart Access Cable Installation
Safety First: Disconnect the Battery! Always begin any automotive electrical work by disconnecting your vehicle’s battery to prevent shorts and ensure safety.
1. Accessing the Security Module Location
Unlike the Challenger, the Dodge Charger Hellcat’s security module is located on the driver’s side, beneath the dash, just above the OBD2 port. To gain access, you’ll first need to remove the driver-side dash end panel. This panel typically pops off with gentle prying.
2. Exposing the Lower Dash Fasteners
Once the side panel is removed, you’ll see two 7mm screws. These screws secure the lower dash panel beneath the steering column. Using a 7mm socket, remove these screws.
3. Unclipping the Lower Dash
With the screws removed, use a trim removal tool to carefully unclip the lower dash section under the steering column. The security module is situated behind a yellow connector, located above the OBD2 port.
4. Identifying the Security Module
You’ll now see the security module, often identifiable by QR code labels.
5. Disconnecting the Top Connector
Locate the top connector harness on the security module and unplug it. This is where the heat-shrinked end of the Smart Access cable will be connected.
6. Installing the Smart Access Cable
Plug the Smart Access Cable connector into the top port of the security module where you just disconnected the original harness.
7. Connecting HP Tuners and Reading Your Tune
With the Smart Access Cable installed, you can now connect your MPVI2 to the OBD2 port. Using VCM Suite, you can proceed to read your stock ECU and TCU tune files. This process usually takes around 10 minutes.
Final Steps and Important Reminders
Before reading your stock tune file, ensure you resync your interface within VCM Suite. This option is located in the “Help” dropdown menu. This ensures a smooth and successful tuning process for your Hellcat Charger Hp gains.
By following these steps, you’ve successfully installed the HP Tuners Smart Access Cable in your Dodge Charger Hellcat, paving the way to customize your car’s performance and maximize that legendary Hellcat horsepower.
