Calibration · Diagnostic intelligence

DTC diagnostics & solutions

A diagnostic trouble code is a starting point, not a parts diagnosis. The workflow preserves the code, description, vehicle context and requested action so the calibrator can review the fault precisely.

WHAT THIS WORKFLOW PROVIDES

Controlled from identification to delivery.

3,700+ searchable codes
DF-to-P alias support
Exact code list on every request
Clear diagnostic context
Compliance requirement

Emissions and safety-related diagnostics must never be used to conceal an unresolved road-vehicle fault.

Why the original file matters

ECU family alone is not enough to identify a safe calibration target. Hardware number, software number, update state, reading method and file integrity all matter. AllChip OS keeps the original read and automatic identity result beside the selected vehicle profile so a mismatch is visible before work begins.

What to send

Upload the unedited original read whenever possible. Add identification files, ECU labels, diagnostic codes, hardware changes, fuel grade and the customer’s technical target. Clear input creates a faster engineering decision and a more traceable result.

After delivery

The result remains attached to the operation with its timestamp, status, engineer note and revision history. If further validation is needed, the workshop can send logs or supporting files without losing the original context.

FREQUENTLY ASKED

Before you submit.

Does clearing a DTC repair the vehicle?+

No. A code should be diagnosed and the underlying fault repaired. Code-related calibration is only considered when technically and legally appropriate.
