For Dodge Charger enthusiasts looking to unlock their vehicle’s full potential with HP Tuners, installing the Smart Access OBD2 cable is a crucial first step. This guide will walk you through the process of locating and bypassing the security module in 2018 and newer Dodge Chargers. Unlike the Challenger, the Charger’s security module is positioned in a distinct location, often causing confusion for those new to tuning these models.
This tutorial provides a clear, step-by-step approach to installing your HP Tuners smart access cable, ensuring you can successfully read your stock PCM/TCM files, make tuning adjustments, and flash new tunes using HP Tuners VCM Suite. By following these instructions, you’ll gain the access needed to fine-tune your Charger’s performance.
Important Safety Precaution: Disconnect the Battery Before Starting!
Step 1: Accessing the Security Module Location
Begin by removing the driver’s side dash panel. This will reveal two 7mm screws that secure the lower dash panel beneath the steering column. You will need a 7mm socket and a trim removal tool for this step.
Step 2: Exposing the Security Module
Using the trim tool, carefully unclip the lower dash section located under the steering column. The security module is situated behind the yellow connector, directly above the OBD2 port. This is the key area where you’ll be connecting your Hp Tuners Obd2 Cable.
Step 3: Identifying the Security Module
You’ll recognize the security module by its QR code labels. This module is what the HP Tuners smart access cable will bypass, allowing for tuning access.
Step 4: Unplugging the Security Module Connector
Locate the top connector harness on the security module and unplug it. This is where you will attach the heat-shrinked end of your Smart Access cable.
Step 5: Connecting the HP Tuners Smart Access Cable
Plug the connector of the Smart Access cable into the top port of the security module where you just unplugged the original harness. This completes the physical installation of the bypass cable.
Step 6: Connecting Your HP Tuners Device and Reading Your PCM/TCM Files
With the Smart Access cable now installed, you can connect your HP Tuners MPVI2 (or other compatible device) to the OBD2 port. Use VCM Suite to read your stock tune files from the ECU and TCU. This process typically takes around 10 minutes.
Final Steps and Important Tip
Before reading your stock tune file, ensure you resync your HP Tuners interface within VCM Suite. This option is located in the “Help” dropdown menu of the software.
By following these steps, you’ve successfully installed your HP Tuners OBD2 Smart Access cable, allowing you to tune your 2018+ Dodge Charger. Enjoy the enhanced performance capabilities!
