Targeted DTC management — Cars / Vans
Processes only the diagnostic trouble codes explicitly supplied after the root cause has been identified. This product is prepared for Cars / Vans and is processed against the exact uploaded ECU or TCU file.
What the service includes
- verification of requested DTC numbers
- targeted software-specific diagnostic change
- confirmation that unrelated diagnostics remain intact
How the order is processed
- Upload the source file. Use the product form and provide complete vehicle, engine, ECU, read-tool and read-method information.
- Identification and verification. We check file integrity, ECU family, available SW/HW identifiers and compatibility with the requested service.
- File-specific work. Only the agreed function is processed. An ambiguous or unsupported variant is held for manual review instead of receiving an unrelated generic solution.
- Delivery and validation. The completed file is returned through the order workflow. Program it with suitable equipment, clear obsolete faults and validate the vehicle with diagnostics and logs.
Required information
List every exact DTC code and provide diagnosis plus the related hardware change.
Technical requirement: Always retain a verified backup of the original read. A partial, corrupt or incorrectly identified file may require a new read before processing.
Responsible use and limits: DTC management must never replace fault finding or hide a safety-critical defect. Additional codes require a separate confirmed scope. The purchaser is responsible for the vehicle condition, lawful use, correct programming procedure and final validation.
Turnaround: Standard processing is normally completed within the service hours shown on the website when the file and technical information are complete. Unusual software variants or manual calibration may require additional confirmation.
