Product Information
Product Description
Bypass Cable – Required for 2018+ Ram Cummins Flashing
A bypass cable is required to unlock and flash 2018 and newer Ram Cummins trucks. Beginning in 2018, Ram implemented enhanced security protocols in the factory gateway module, which prevent direct communication between the ECM/TCM and aftermarket tuning devices.
The bypass cable temporarily reroutes communication around the factory security gateway, allowing supported tuning devices to safely read, write, and flash the ECM (and TCM where applicable).
Why the Bypass Cable Is Required
- Factory gateway blocks tuning access on 2018+ Ram Cummins
- Prevents flashing without an approved bypass solution
- Required for custom tuning, SOTF files, and transmission tuning
- Does not alter factory wiring permanently
Key Notes
- Required for initial flashing and future tune updates
- Plug-and-play design for straightforward installation
- Allows full communication between the tuning device and vehicle modules
- Must be installed before attempting to flash the truck
Compatibility
- 2018+ Ram Cummins 6.7L
- Works with supported tuning platforms and devices offered by Dyno Diesels
Installation
- Simple inline install at the gateway module
- Can be removed after flashing if desired (unless required for future updates)
- Follow all tuning and installation instructions carefully
Using the proper bypass cable ensures a safe, reliable flashing process and prevents communication errors during tuning.
