Can one pass the annual inspection if the high-mounted brake light doesn't work
Youdaoplaceholder0 If the high-position brake light does not light up, it cannot pass the annual inspection , because the annual inspection requires all brake lights to be working properly; otherwise, it cannot pass the safety inspection.
Reasons and basis
The high-mounted brake light is an important component of the vehicle's safety system. Its functions include:
Youdaoplaceholder0 Enhance warning effect : Located at the upper part of the rear of the vehicle, it can shorten the braking distance of the vehicle behind (4.9 to 7.4 meters at a speed of 88km/h), reducing the risk of rear-end collisions.
The regulation mandates that : annual inspection shall be based on the "Technical Conditions for the operation Safety of motor Vehicles", and all brake lights (including high-altitude lights) must be inspected. If it does not light up, it will be judged as not meeting safety standards.
Repair suggestions
To ensure passing the annual inspection and guarantee driving safety:
Youdaoplaceholder0 Timely maintenance : Check fuses, switches or bulbs, and give priority to LED light sources (fast response and long lifespan).
Youdaoplaceholder0 Professional inspection : Before the annual inspection, have the lighting system tested at a regular repair shop to avoid non-compliance due to partial non-lighting.
The solution to the fault of the high-mounted brake light should be checked step by step according to the type of fault (such as no light or constant light), . The core steps include checking the bulb, brake light switch, circuit, fuse and control module . Common problems (such as bulb damage) should be dealt with first. If it is difficult to solve by oneself, professional help should be sought to ensure driving safety.
Cause of failure and solution steps
The malfunction of the high-mounted brake light is usually manifested as no light or constant light. The main causes and solutions are as follows:
Youdaoplaceholder0 bulb failure (most common cause) :
Operation steps: Turn off the vehicle power → Open the trunk and remove the lampshade → Take out the old bulb (avoid touching the glass) → Install a new bulb and test it.
Youdaoplaceholder0 brake light switch failure :
The switch is located near the brake pedal. If there is poor internal contact or damage, it needs to be replaced.
Test method: Gently press the brake pedal to feel the resistance, or use a multimeter to check the power supply of the circuit (if neither of the two wires is powered, it may be a fuse problem; if only one wire is powered, the switch is faulty).
Youdaoplaceholder0 Circuit or fuse problem :
Check if the circuit is damaged, aged or short-circuited, and repair the connection points or replace the circuit.
When the fuse blows, replace it with a fuse of the same specification (usually 10A or 15A). If it melts again after replacement, it indicates a short circuit in the circuit and requires professional maintenance.
Youdaoplaceholder0 control module failure (high-end model) :
Faults in the vehicle body computer or control module may cause fault codes, which require professional equipment for diagnosis or reset.
Precautions
Youdaoplaceholder0 Safety first : Turn off the power and disconnect the battery before operation to avoid the risk of electric shock.
Youdaoplaceholder0 self-inspection scope : bulbs, switches and fuses can be handled by oneself; It is recommended to send for repair if there are any issues with the line or module.
Youdaoplaceholder0 Timely repair : Brake light malfunctions affect driving safety. Once discovered, they should be dealt with immediately.
"Check the high-mounted brake light" is a warning message displayed on the vehicle's dashboard, indicating that the high-mounted brake light (also known as the third brake light) may be faulty or failed and needs to be repaired promptly to ensure driving safety. Youdaoplaceholder0 This prompt originates from the vehicle 's self-check system and is usually triggered by a damaged bulb, wiring issue or sensor failure. If left untreated, it may increase the risk of rear-end collisions.
Definition and Location
The High brake lights are the third brake lights installed at the upper part of the rear of the vehicle, on the top of the rear windshield or at the center line of the rear end. They serve as auxiliary devices for the brake lights on the left and right sides and are used to enhance the visibility of braking signals.
Check the causes and suggestions
Youdaoplaceholder0 Fault trigger : The dashboard prompt is usually caused by damaged LED light source, short circuit or sensor abnormality, and professional diagnosis is required.
Youdaoplaceholder0 Handling suggestion : immediately go to a 4S store or professional repair point for inspection. Avoid disassembling it by yourself. Give priority to using LED light sources (fast response, long lifespan, and 87% power saving), and conduct regular checks to ensure normal functionality.
