Incorrect decoding of the letters of the auction sheet, for example, confusion between the code XX (panel replacement) and W (restoration), often leads to the purchase of a car with hidden major body repairs. Unlike the usual European standards, the Japanese defect marking system uses alphanumeric designations that are applied directly to a schematic image of the car. Understanding these symbols allows the buyer to instantly assess the actual technical and visual status of the vehicle without relying solely on the overall auction score.
Each symbol on the diagram carries specific information about the nature of the damage: the letter indicates the type of defect, and the number indicates the degree of its severity or size. Ignoring these marks when analyzing a lot can result in unpleasant surprises during customs clearance or subsequent use. A professional approach requires a careful examination of every square on the body, since even a scratch that seems insignificant at first glance can hide a deeper problem.
Japanese auctions do not hide the real condition of the car, unlike many domestic sites, so the ability to read their “language” is the key to a good deal.
Labeling principles and assessment structure
The Japanese rating system is based on a detailed examination by an expert of each body element. The basis for the analysis is a schematic view of the car from the front, rear and side, where the codes are located. Numbers from 1 to 3 (sometimes 4) indicate the degree of damage, where 1 is a barely noticeable defect, and 3 requires serious intervention or replacement. The letter designations classify the very nature of the problem, whether it is mechanical stress, corrosion or repair work.
It is important to distinguish between a general condition rating (Grade), which is given in the form of a number and a letter (for example, 4 or A), and a detailed map of defects. The overall rating may be high if the defects are minor and not noticeable, but the body map will show the exact number. Auction sheet is a legal document, and the auction is responsible for providing false information, so the data there is as honest as possible.
- 🚗 Letter codes indicate the type of defect (scratches, dents, rust).
- 📏 Digital indexes indicate the size or depth of damage.
- 🔍 Schematic layout symbols exactly corresponds to the location of the defect on the body.
Indications of external damage to the body
The largest number of symbols on the diagram usually refer to external panels. Code U (Umi) means dent. If you see next to the door U2, this is a medium sized dent that will likely require straightening and painting. More serious damage is indicated as UU - This is a large dent or impact, often implying the difficulty of restoring the geometry of the part.
Scratches are marked with a letter W (may appear as S in some classifiers, but W is more common for superficial damage) or A (for large abrasions). However, you should be careful: the letter W can also mean "Wave" or repair, so context is important. For scratches, gradation is most often used: W1 - barely noticeable scratch, W2 - a scratch that can be felt with a fingernail, W3 - deep scratch to metal.
⚠️ Attention: There are multiple marks U or UU on one panel may indicate careless operation or parking incidents, which requires a thorough check of the paintwork with a thickness gauge.
Particular attention should be paid to the code XX. This symbol indicates that the body panel has been completely replaced. If it's on the wing XX, which means the original element is not there. This is not always bad (for example, when replacing after a minor accident), but it requires checking the quality of assembly and painting. Double designation XXX This is rare and indicates the replacement of several adjacent panels or complex body repairs.
Corrosion and paint problems
For Japanese cars, especially older ones, the condition of the metal is a critical parameter. Letter R (Rust) indicates the presence of rust. The degree of corrosion development is indicated by a number: R1 - surface oxidation or incipient rust, R2 - noticeable corrosion that requires cleaning, R3 — through corrosion or holes. There is also the designation Rr, which means rust repair is a thing of the past.
Problems with varnish and paint stand out separately. Code C (Corrosion) is sometimes used as a synonym for rust, but more often refers to the corrosion of specific elements, such as fasteners. Symbol P (Paint) or P2 indicates that the part has been repainted. If it's worth it just P, this may mean local coloring or polishing. Complete repainting of the body is designated as W (meaning Whole) or special marks in the text part of the sheet.
Hidden corrosion
Rust is often hidden under plastic covers or in chipped areas. If you see R1 or R2, be sure to check for hidden cavities.
Cracks on the body or bumpers are marked with a letter X. X1 - small crack, X2 - more serious damage. For plastic items such as bumpers, cracks may be repaired but will be fairly noted on the auction listing. Glass with cracks is marked as G (Glass) with the corresponding number, which is a direct indication of the need to replace the glass.
Defects in interior, glass and optics
The state of the interior is described by separate codes, which are often found in a text description or on a separate interior diagram. Letter AC (Aroma Cigarette) indicates the presence of the smell of tobacco, which is a serious disadvantage for the Japanese market and greatly reduces the price. Code AS (Aroma Something) may refer to other foreign odors, such as animal or damp.
Tears and abrasions on the seats are marked with a letter B (Break) or T (Tear). B1 - a small tear that can be sewn up, B3 - serious damage to the upholstery. Stains on the ceiling or seats are indicated as S (Stain). The cleanliness of the interior directly affects the final cost of the lot, since the Japanese are very demanding about hygiene in the car.
| Code | Decoding | Recommendation |
|---|---|---|
| AC | Smell of cigarettes | Requires dry cleaning, ozonation |
| S | Stain (Salvage/Stain) | Penetration depth check |
| G | glass crack | Element replacement is required |
| H | Damage to optics | Polishing or replacing headlights |
Optics and glass are checked for chips and cracks. Code H indicates damage to the Headlight. H1 - small chip, H2 - crack. Window tinting is designated as FT (Film). If the tint does not meet the standards of the country of import, this must be taken into account as additional costs for removing the film.
Technical marks and repair history
The technical condition of the units is also reflected in the sheet, although in less detail than the body. Code J (Joint) indicates a replacement part, but is more often used for body parts. Leak marks are important for the engine and transmission. Oil leak may be written in text or indicated with special icons depending on the auction.
Of particular interest is the record of past repairs. If the car has been in an accident, but has been properly restored, it can receive an assessment R (Repair history) in the overall rating column. This does not mean that the car is bad, but its price will be lower than an analogue without a repair history. Deciphering the letters of the auction sheet in this case helps to understand the scale of the past accident.
☑️ Checking the technical part
The chassis is checked for play and wear. The text field may contain information about replacing shock absorbers or levers. If the remarks column indicates Low tire, this means that the remaining tread height of the tires is minimal, and they will have to be changed immediately after purchase.
Common mistakes when decrypting yourself
Beginners often confuse similar symbols or do not attach importance to numbers. For example, U1 and U3 - these are defects that are fundamentally different in terms of labor intensity to eliminate. It is also a mistake to think that the presence of defects automatically makes the car “broken.” Small W1 or U1 There are 90% of used cars and are the result of natural use.
Another common mistake is ignoring text comments. The letter codes on the diagram are only part of the information. In a text block Remarks may contain important information: for example, that navigation does not work, or there is only one key. These nuances are not visible on the body diagram, but affect the price and comfort.
⚠️ Attention: Do not try to evaluate a car only by its overall rating (Grade 4, 4.5). Always look at the defect map, since Grade is the average opinion of an expert, and the map shows the real picture.
Main conclusion: There are no ideal used cars; it is important to correctly assess the ratio of price and volume of required investments, based on defect codes.
Final assessment and decision making
Correct decoding of the letters of the auction sheet allows you to form an objective opinion about the lot even before its purchase. Summarizing the body data (U, W, XX), salon (S, AC) and technology, you can calculate the approximate cost of restoration. If the price of the lot, including repairs, is lower than the market price, the transaction is considered profitable.
The use of translators and code books is mandatory when first getting acquainted with Japanese auctions. Over time, the basic notations are remembered, and the analysis process takes a matter of minutes. Remember that the auction sheet is your main tool for protecting against buying a “pig in a poke.”
What does the R rating mean on the auction sheet?
Evaluation R (or RA, RB) indicates that the vehicle has a body repair history. This could be replacing a bumper after a minor accident or serious restoration after an accident. Cars with an R rating are usually cheaper than their counterparts without a repair history, but require a more thorough check of the body geometry.
What is the difference between U2 and UU?
U2 indicates a medium-sized dent that can usually be corrected by straightening. UU (or U3) means a large dent, often with creases in the metal, that may require panel replacement or complex body repairs. UU is always more serious than U2.
Can the auction sheet be trusted?
Yes, Japanese auctions value their reputation. Experts undergo strict certification. However, the human factor cannot be excluded: the expert may not notice a hidden defect or assess the degree of damage subjectively. Therefore, the sheet is an excellent guide, but a personal inspection or the services of an independent expert upon receipt of the car will not be superfluous.
