Diagnostics of these vehicles requires specialized equipment capable of working with dozens of control units, complex system tasks, calibrations, adaptations, and service modes. One such solution is the new LOKI PRO diagnostic kit, developed specifically for in-depth analysis of diagnostic data and restoration of Rivian vehicles.

Complexity of Modern Rivian Systems

Rivian’s architecture is built on many interacting control modules. Unlike traditional vehicles, nearly all systems—from the battery pack and electric motors to the suspension and driver-assistance systems—are managed by digital controllers connected via high-speed communication buses.
For a repair specialist, this means the following:● An error in one module may be caused by a failure in another.● Any incorrect operation can switch the vehicle into a protective or service mode.● Incompetent diagnostics can lead to function lockout or even prevent the vehicle from starting.Therefore, universal OBD scanners are not suitable here. Working with Rivian vehicles requires a specialized tool that supports a full range of functions at the level of dealer equipment—exactly what LOKI PRO provides.

LOKI PRO Capabilities for Rivian

LOKI PRO is a specialized diagnostic complex designed specifically for Rivian vehicles. The device combines custom hardware and advanced software developed to perform both standard and highly complex diagnostic tasks.

Key Functions of LOKI PRO:

1. Working with Diagnostic Trouble Codes (DTCs)The scanner allows users to:● read all trouble codes from every ECU in the vehicle;● access detailed descriptions of detected issues;● clear DTCs after repairs are completed.The key advantage of LOKI PRO is its ability to communicate with the full set of Rivian modules, including high-voltage systems, ADAS, battery management, and suspension control.
2. System Tasks, Calibrations, and AdaptationsThis functionality is especially important for modern EVs, as many service procedures require software activation.LOKI PRO enables:
● sensor and system calibrations,● adaptation of new components,● system initialization after repairs,● actuator testing,● resetting and configuring safety systems.For Rivian, where many functions are tightly tied to the vehicle’s software state, such operations are essential.

3. Simple Connection via OBD2 PortConnection to a Rivian vehicle is performed through the standard OBD2 port. This keeps the process simple and eliminates the need for additional adapters or direct access to individual control modules. It speeds up workflow and minimizes operator error.
4. ECU Unlinking from the VehicleOne of LOKI PRO’s unique features is the ability to “unlink” an ECU from a specific vehicle before removal. This is particularly useful when installing a module taken from another vehicle, for example one damaged in a severe accident and deemed non-repairable. technical maintenance actions. It is within Odin that the firmware and commands we discussed earlier are located. However, despite Odin being based on Python 3, direct connection to the vehicle yields no results - without proper authorization, the car's computer simply throws an error.

5. Live Data ReadingLive Data is a crucial tool for diagnostics, providing real-time monitoring of vehicle parameters. LOKI PRO displays streaming parameters from all Rivian systems, including:● high-voltage battery voltage and current,● module status and balancing,● temperature readings,● inverter load,● ADAS operation,● electric drive activity,● sensor and actuator status,● and more.
6. Vehicle Recovery After an AccidentRivian vehicles use numerous safety modules that may lock certain functions after a collision.LOKI PRO includes tools that allow users to:● properly reset crash states,● restore airbag system operation,● return the vehicle to full functionality after repairs.
7. Service Mode ActivationDuring maintenance, many Rivian systems require switching the vehicle into service mode. The scanner enables this for all major systems, including:● the high-voltage battery,● the electric platform,● the brake system,● the ADAS module.

Updates and Technical Support Subscription

When purchasing LOKI PRO, the user receives one year of free updates and full access to technical support, including assistance with complex diagnostic cases. After the first year, the subscription is renewed annually. This ensures that LOKI PRO remains up-to-date and compatible with the latest Rivian models and software versions.

Conclusion

Rivian vehicles are advanced, highly complex electric cars that require a professional approach to diagnostics. The new LOKI PRO scanner provides specialists with a complete set of tools for working with these vehicles at a dealer-level standard. From reading trouble codes and analyzing live data to performing adaptations, calibrations, accident recovery, and ECU unlinking—LOKI PRO ensures deep, accurate, and safe diagnostics of any Rivian system. This makes it an indispensable tool for service centers working with modern electric vehicles.
