Introducing the latest enhancement to the Alientech KESS3 toolkit: the DTC (Diagnostic Trouble Code) feature. This powerful new functionality is designed to streamline your tuning and diagnostic processes, providing enhanced efficiency and profitability for your business.

What is the DTC Feature?

The new DTC feature allows for the detection, interpretation, and resetting of error codes (SAE) stored in engine control units (ECUs) via the OBDII connection. SAE (Society of Automotive Engineers) error codes are standardized codes used to identify specific problems in vehicles, making this feature particularly useful for pre- and post-tuning diagnostics.

Key Benefits of the DTC Feature

1. Detection and Interpretation of Error Codes:

The DTC feature helps you quickly identify vehicle problems without needing additional devices. By centralising the diagnostic process, it reduces the time needed to pinpoint faults and increases work efficiency. When connected to the ECU, KESS3 retrieves a detailed list of present error codes, including their descriptions, allowing you to accurately diagnose issues.

2. Resetting of Error Codes:

After repairs, the DTC feature enables you to remove error codes from the ECU memory, ensuring the vehicle operates correctly. This is crucial for confirming that repairs have been properly executed and that the vehicle no longer shows fault signals, which improves customer satisfaction and reduces return visits.

3. Pre-Tuning and Post-Tuning Diagnostics:

The DTC feature allows you to assess the feasibility of modifications before tuning by displaying any existing errors that could affect the tuning process. After tuning, it checks for new errors to ensure that the modifications have not introduced problems. This process ensures that the vehicle is in perfect condition before and after each intervention, minimizing the risk of damage and malfunctions.

4. Special Functions:

The DTC feature includes specific options for certain vehicle models, such as steering alignment and differential lock/unlock. Supported models are visible within Alientech Suite, the KESS3 software, providing users with an extended range of diagnostic and customization functionalities.

How to Use the DTC Feature

Using the DTC feature with KESS3 is straightforward:

1. Connect to the Vehicle: Connect KESS3 to the vehicle via OBD and ensure an active internet connection to open the protocol for the test.
2. Select the Vehicle: Choose your vehicle from the list on Alientech Suite and select the “DTC” option.
3. Scan for DTCs: Start the code scan and wait for KESS3 to generate a list of any faults present in the ECU.
4. Clear the DTCs: Press the ‘Clear DTC’ button to reset the engine fault codes stored in the ECU memory.

Availability and Subscription

The DTC feature is available only to customers with an active KESS3 subscription and at least one activation (Car-LCV OBD, Car-LCV Bench/Boot, Bike OBD, Bike Bench/Boot). If your KESS3 has one of these activations, you will automatically receive the new feature. However, if the subscription expires, the DTC feature will cease to function and will be reactivated upon renewal of the subscription.
