Define the buyer’s real question
Confirm fitted equipment by version, then test each available function safely; a clear dashboard cannot prove sensor alignment or destination support. If front glass was replaced, review the windscreen and ADAS repair evidence.
Record destination, intended registration, steering side, daily and long-distance route, passengers, luggage, charging access, accepted powertrain, new or used condition, budget and delivery point. A changed candidate or destination reopens affected checks.
Apply the model-specific test
List only the cameras, radar, ultrasonic sensors, warnings and assistance functions fitted to the identified version. Inspect mounting and surrounding repairs, scan relevant modules, calibrate where the approved procedure requires it and perform a controlled functional check without treating assistance as autonomous driving.
Connect sensor findings to the broader used UNI-Z inspection, then verify software and region behaviour and price any calibration or parts through the ownership-support plan.
Official context: Review the current Changan UNI-Z product page and match it to the selected vehicle.
Evidence specific to this decision
Record fitted functions, sensor condition, module faults, repair history, calibration evidence and the exact road or parking test performed.
Identify fitted assistance before testing it
UNI-Z equipment can vary by powertrain, production version and trim. Create a fitted-feature sheet from the selected car rather than copying a top-trim advertisement. Photograph camera areas, radar or sensor covers, parking sensors, windscreen zones and the relevant controls. Note replaced glass, bumper repairs, paint work, brackets, warning messages and diagnostic faults because a clean exterior does not prove that a sensor sits at the intended angle.
Separate passive safety equipment, warning functions, parking aids and driving assistance. Record whether a feature is absent, present but untested, tested normally or requires diagnosis. Translation and menu availability may affect operation overseas, while destination rules may restrict use. No assistance function removes the driver’s responsibility or establishes autonomous-driving capability.
| Check stage | Evidence |
|---|---|
| Static | Mounting, glass, bumper, lens and connector condition |
| Electronic | Module identity, current faults and calibration status |
| Controlled test | Function, conditions, warning behaviour and limitations |
| Handover | Settings, unresolved faults and buyer briefing |
Treat calibration as evidence, not a checkbox
A windscreen, bumper, alignment or suspension repair may change the calibration question even when no warning lamp remains. Preserve the repair scope, scan report, calibration method and result from a suitable service provider. During a road or parking test, use legal, controlled conditions and record exactly what was observed; do not provoke an emergency intervention. An intermittent, unavailable or unsupported function belongs on the cost and acceptance list before deposit.
Keep one VIN across the file
Inspection joins structure, paint, underbody, tyres, brakes, road behaviour, diagnostics and history to one VIN. PHEV candidates add battery enclosure, charging and high-voltage diagnostics; gasoline cars add cold-start and DCT tests.
Preserve original-language records beside translations. Connect photos, diagnostic output, charging or road tests, inspection, quotation and contract to the same VIN. Conflicts stop approval until resolved at source.
| Evidence | What to record |
|---|---|
| Identity | VIN, production plate, legal model, powertrain and version |
| Condition | Dated physical checks, history, diagnostics and test results |
| Compatibility | Destination consequence, limitation and responsible reviewer |
| Commercial | Seller, beneficiary, included work, validity and delivery term |
Inspection depth
Begin cold where applicable, then test low speed, cruise, acceleration, braking and uneven surfaces. Recheck leaks, warnings and diagnostics. iDD adds EV transitions and charging.
Record location, severity and repair consequence. Keep cosmetic, structural, mechanical, high-voltage and software issues separate.
Test an ordinary day and an adverse day
Use realistic passengers, luggage, weather, speed, gradients, traffic and energy availability. For iDD, include a failed charger and battery reserve. For gasoline, include local fuel, emissions and workshop constraints. A specification is context, not a guarantee of suitability.
Mark each conclusion green, amber or red with evidence date and owner. Amber needs a priced consequence or condition; red stops payment. Do not turn missing proof into a positive feature claim.
Preserve the approved vehicle to delivery
Carry VIN, version, condition and included work through quotation, contract, invoice, export records and loading media. Record odometer, fuel or charge state, keys, cables, accessories, faults and exterior condition at handover.
China-side work cannot promise destination tax, conformity, registration, charging access, software services, warranty, insurance or future reliability. Refresh local advice if vehicle, route or rules change.
Request a VIN-linked UNI-Z proposalDocuments that keep this decision usable
Create a candidate summary naming the VIN, production date, legal model, powertrain, version, odometer and seller. Attach original identity records, continuous dated media, inspection findings, diagnostic output, road-test notes and charging results where applicable. Each conclusion should identify its source, test condition, limitation, reviewer and expiry point.
Keep the commercial file separate but connected: dated quotation, included and excluded work, inspection conditions, contract entity, bank beneficiary, export responsibility, carrier acceptance and delivery boundary. The destination file records tax or duty advice, conformity, registration, insurance, energy access and workshop support. A changed input reopens the affected decision while preserving the audit trail.
Before loading, compare the approved summary with the physical vehicle and final documents. Record keys, cables, accessories, odometer, fuel or battery state, warnings and visible condition. This final comparison helps prevent a correct inspection being attached to the wrong car.
Buyer questions
Can a warning-free dashboard prove ADAS condition?
No. Check fitted equipment, sensor mounting, repair history, module faults, calibration evidence and controlled function tests.
Does every UNI-Z have the same assistance equipment?
Do not assume so. Production version, powertrain and trim can change fitted functions, so build the feature list from the identified car.
Should emergency functions be deliberately triggered?
No. Use safe, legal test procedures and qualified diagnostic or calibration evidence rather than provoking a hazardous intervention.
