Targeted diagnostic trouble code handling with explicit code selection.
Professional service scope
The exact DTC list stays with the order so unrelated diagnostic functions are not intentionally changed.
Complete code formatting and the underlying diagnosis help distinguish a valid request from symptom masking.
DTC work must not be used to bypass safety-critical systems, required diagnosis or legal obligations.
Targeted management of explicitly requested diagnostic trouble codes in a supported ECU or TCU file. It is designed for controlled workshop workflows where the underlying fault has already been identified and the requested codes are known.
The selected DTCs are stored with the order and passed through the same verified file-identification process. Only requested, supported codes are considered; unrelated diagnostic functions are not intentionally removed.
The uploaded binary and software identifiers determine compatibility.
Unverified matches are never presented as an automatic solution.
Unsupported files can continue through the central support workflow.
Enter the complete code format, for example P0401 or manufacturer-specific equivalents, and describe the diagnosis. Supply the original file and avoid using a previously modified binary unless that history is clearly declared.
DTC management is not a substitute for diagnosis and cannot guarantee removal of dashboard messages controlled by another module. Safety-critical systems and legal obligations must not be bypassed.
