Annual vehicle inspection is a step that every car owner must face, but many car owners encounter the dilemma of "failed inspection" because their vehicles do not meet the standards. This article combines the hot topics on the Internet in the past 10 days to sort out high-frequency problems and practical solutions to help you pass the annual inspection efficiently.
1. Top 5 common reasons for vehicle failure in annual inspection
| Ranking | Unqualified items | Proportion | Typical performance |
|---|---|---|---|
| 1 | Exhaust gas emissions exceed standards | 38.7% | CO/HC value exceeds limit |
| 2 | Braking system failure | 22.5% | Unbalanced braking force/braking distance is too long |
| 3 | Lighting system issues | 15.3% | Insufficient brightness/illumination angle deviation |
| 4 | Abnormal tire wear | 12.8% | Pattern depth <1.6mm/cracks |
| 5 | Appearance modification violation | 10.7% | Illegal color change/addition of surround |
2. Solutions to sub-problems
1. Excessive exhaust emissions
•Short term emergency:Keep the engine at high temperature before testing (it is recommended to test after driving 10 kilometers)
•Mid-term maintenance:Replace the three-way catalytic converter (market price 800-3,000 yuan)
•Long-term maintenance:Clean the throttle every 5,000 kilometers and use regular gas station fuel.
2. Braking system failure
•Basic processing:Replace the brake pads (it is recommended to replace the front wheels every 40,000 kilometers)
•In-depth maintenance:Repair ABS pump (failure rate is about 7%)
•Detection skills:Press the brakes repeatedly to release the air before going online
3. The latest policy points in 2023
| Policy changes | Implementation time | Scope of influence |
|---|---|---|
| OBD detection enhanced | 2023.1.1 | Vehicles registered after 2011 |
| Tire inspection upgrade | 2023.6.1 | All models |
| Special inspection of new energy vehicles | 2023.9.1 | Pure electric/hybrid models |
4. A must-have annual inspection tool kit for car owners
•Self-check artifact:OBD-II detector (recommended brands: Launch, Carsmith)
•Emergency supplies:Brake oil moisture content test pen (<3% is qualified)
•Document preparation:Copy of compulsory traffic insurance, copy of vehicle owner’s ID card
5. Special reminder from experts
1. Make an appointment 30 days in advance to avoid the testing peak (the failure rate is reduced by 40%)
2. Modified vehicles need to be registered 10 working days in advance (the latest traffic control number 12123 can be processed online)
3. Failure to pass three re-inspections will require forced scrapping (according to the "Compulsory Scrapping Standards for Motor Vehicles")
Through system analysis, it can be seen that 90% of detection failure cases can be avoided through advance self-inspection. It is recommended that car owners establish a semi-annual pre-inspection mechanism and break down the annual inspection items into daily maintenance, which can not only ensure driving safety, but also easily pass the annual inspection.
