| OEM terminology across ranges & model years | If a part is called one thing in the predecessor and another after the facelift, the spare-parts catalogue, workshop manual and owner's handbook contradict one another — and the mechanic cannot find the part. | We maintain the OEM nomenclature as a binding terminology database per vehicle programme and enforce every designation across ranges and model years — not by linguistic feel. |
| Part & spare-part numbers (SKU) | Item, spare-part and order numbers must never be translated or "corrected". A single altered digit simply orders the wrong part. | Numbers, codes and variables are locked as protected segments in the CAT tool and checked for completeness in the final review. |
| Functional safety & standards (ISO 26262, VDA) | Terms such as ASIL classification, "safety goal" or "fault-tolerant time interval" carry a defined meaning in control-unit and test documents. A free translation breaks the evidence chain. | Specialists with an E/E and standards background render ISO 26262 and VDA terminology exactly and reconcile it with your specifications and datasheets. |
| Diagnostic trouble codes (DTC) & plain text | DTC codes (per ISO 15031-6 / SAE J2012) are fixed; only the plain text is translated. Touch the code or make the text ambiguous, and the diagnostic device points nowhere. | Codes stay unchanged; we translate fault texts against a curated diagnostic glossary and reconcile them with the plain texts in the control unit. |
| Infotainment / HMI strings with character limits | A display text that is 30–40% longer in German is truncated in the cockpit — "driver assistance deactivated" does not fit the field for "ACC off". | We translate UI strings against the character / pixel limit per field, shorten while preserving meaning, and deliver working resource files with no broken placeholders. |
| Units & electrical / on-board-network terms | Torque, pressure, voltage and separators are market-dependent: "1,000 V" means one thing in Germany, a thousand in the US. With high voltage that is not a typo but a safety error. | Units and separators are localised, conversions applied only on instruction and flagged; electrical and on-board-network terms follow the standardised designation. |
| Warning & safety notices (high-voltage / e-drive) | With HV systems the level of obligation decides — "must not" is not "should not". A weakened warning is a product-liability risk. | Warnings are rendered word-for-word, signal words drawn from a fixed word list, the modality preserved exactly — checked under the four-eyes principle. |
