Capture the whole message and the circumstances
Photograph the full instrument screen, not just two letters or a translated chat message. Record the symbol, colour, exact wording, ignition or driving state, odometer and whether the message remains after normal starting. Keep the time and vehicle identity beside the observation. Ask the driver what happened immediately before it appeared, without suggesting an answer. A tyre change, battery event or repair may be useful history but does not establish causation. If the car shows a warning requiring immediate stopping under its manual, do not ask for another road test to create a more convincing video. Safety takes priority over documenting a purchase.
Use the manual for the actual vehicle
Confirm original market, model year, powertrain and instrument language before selecting the owner manual. Petrol T2 and an i-DM or C-DM candidate should not automatically share a warning interpretation. An online explanation for another Jetour model is not sufficient evidence. Obtain the applicable manual through the manufacturer or legitimate market support route, and keep the original wording with any translation. Where TP/TT remains ambiguous, leave its meaning unresolved rather than publishing a confident expansion of the letters. The T2 and Traveller version guide establishes the identity needed for this step before any warning-specific repair is priced.
Keep tyre checks separate from a diagnosis
If the identified message concerns tyres, first record the fitted tyre sizes, visible condition, pressure-label requirements and the actual cold-pressure measurement by an appropriate operator. Do not quote one internet pressure for every version and load. A pressure display and a physical gauge can answer different parts of the inspection, and neither rules out every wheel or sensor problem. The T2 tyre and TPMS guide covers the wider fitment check. Have damaged tyres or abnormal pressure addressed safely before driving; avoid repeated resets intended to hide a warning without confirming why it appeared.
Request a useful diagnostic record
For an unresolved warning, ask a qualified technician for the VIN-linked scan date, equipment used, affected module, exact codes and accompanying observations. Preserve the report before clearing anything. A fault code describes an observed condition within a system; it is not necessarily a complete parts-replacement instruction. Ask whether the relevant tests were completed, which finding supports the proposed remedy and what remains untested. Battery state and operating conditions may matter, so record them rather than treating all scans as directly comparable. The used T2 inspection checklist should retain the warning and diagnostic evidence under the same candidate record.
Require repair evidence and a relevant repeat check
A warning disappearing once does not prove a lasting remedy. Record the diagnosed cause, work completed, parts used where applicable and the conditions of the repeat check. The relevant confirmation may involve a normal operating cycle or a workshop procedure, not merely starting the car again. Never stage hazardous tests of brakes, assistance systems or overheating protection to reassure a buyer. If a repair requires calibration or programming, preserve that evidence too. The T2 sensor-calibration guide is useful where related repairs affect fitted assistance equipment, but its presence does not make every warning a sensor fault.
Decide with uncertainty visible
Compare the candidate only after the warning is explained or explicitly left unresolved. Distinguish a demonstrated repair cost from an untested symptom and record who owns the next diagnostic action. A discount does not turn a safety concern into an acceptable condition report. For a serious unresolved system issue, pausing or rejecting the vehicle may be more sensible than budgeting a guessed replacement part. The landed-cost guide can carry verified corrective work separately from the purchase price. Preserve the original message, scan and follow-up findings so an arriving workshop can understand what was observed before export.
Example: a message returns after a tyre change
Suppose the seller explains an abbreviated warning as normal after fitting wheels and offers to reset it immediately. Ask for the original message and the wheel, tyre and sensor record first. If the applicable manual and inspection support a simple procedure, have the work completed and documented. If fitment is wrong or the diagnostic finding remains unexplained, the reset has not resolved the buying question. Keep the car on hold while the responsible workshop identifies the issue. This sequence avoids both exaggerating a benign observation and treating an undiagnosed warning as harmless because it briefly disappears.

Buyer questions
Does TP/TT have one guaranteed meaning on every T2?
No universal interpretation is established here. Use the full message and applicable vehicle manual rather than expanding the letters by guesswork.
Does clearing the warning prove the car is repaired?
No. Preserve the diagnosis, completed work and relevant repeat-check evidence.
