How many Mazda 6, CX-5, CX-9, or other models have a “SCBS inspection required” light on the dashboard? We are temporarily disabling the driver assistance and safety systems. The dashboard also displays a light.
There may be headaches and difficulties associated with this matter, so do not take it lightly. Mazda’s dashboard has an easy-to-understand method for clearing SCBS warnings.
Here you will find instructions on how to resolve the smart city brake support (SCBS) error without consulting a mechanic at the dealership. The error message will disappear from the dashboard if you carefully follow the instructions.
Here are some possible causes and solutions to the process.
What Is SCBS?
In order to understand SCBS, we must first understand its operation. In Mazda vehicles, it enhances the safety system with an advanced safety feature. As a result, the brakes are automatically applied to ensure that low-speed collisions are prevented and minimized.
An SCBS system can detect vehicles, cyclists, and pedestrians moving between speeds of war and 80 kilometers per hour using a camera mounted on the windshield.
If the Mazda 6 detects a collision with a high-risk factor, the smart city brake support system will prime the brakes to enhance braking performance. It will automatically apply the brakes after you do not apply them, even if you do not apply them.
Why does the warning light “SCBS Inspection Required” appear?
There is a problem in the SCBS system requiring quick repair or replacement. The “SCBS inspection required” warning light indicates that a repair or change needs to be made. There is either a malfunction or a sensor turn-off issue causing the SCBS system to stop working correctly, hence this warning light.
Warning light “SCBS Service Required” causes
SCBS malfunctions on the dashboard can be caused by a number of reasons, as follows:
- Sensor malfunctioning or disabled
- An emblem sensor on the front grille is faulty
- Electrical problems
- Battery voltage is low
- Software issues
Sensor failure or malfunction
Clean, damaged, malfunctioning, or snow-covered laser sensors and windscreen cameras are the most common causes of safety and driver support systems turning off. The SCBS system is controlled when sudden braking occurs due to laser sensors monitoring vehicles and pedestrians on the road.
An emblem sensor on the front grille is faulty
Mazda vehicles are protected against obstacles by the grille emblem sensor and pedestrians from collisions. There is a possibility that an SCBS inspection will be required because of a faulty or damaged grille emblem.
Electrical Problems
The connection between the computer and Mazda SCBS components can be disrupted by wiring or electrical problems like faulty dashboard bulbs and fuses.
SCBS components, such as emblem sensors and windscreen laser sensors, will receive incorrect signals as a result of this interruption, resulting in an error message.
Battery voltage is low
Using the battery, the SCBS can analyze vehicles on the road by providing sufficient electric current to its sensors. Battery voltage issues can prevent SCBS sensors from functioning as they should, resulting in messages not being displayed.
Software Issues
Software may have bugs, code errors, or other defects, but the other components may work properly.
Service Required Error in SCBS Solutions
Smart city brake support service might be fixed by these valuable solutions.
- Sensors cleaning
- Inspection of physical damage
- Checking electrical components
- Battery replacement
- Mechanical inspection
- System reset
Sensors need cleaning
Cleaning all the sensors should be your first step, since sometimes these sensors are not faulty, but instead blocked by snow and fail to function. I’ll tell you how to do it in three easy steps
- Get out of your Mazda and turn off the engine.
- Cleaning the laser sensor on the windshield is the second step.
- Lastly, take an opportunity to clean the grille emblem sensor at the bottom of the grille.
The SCBS inspection required light will disappear from the dashboard as soon as you start the engine.
Note: Make sure your sensor is always protected by wiping away snow, dirt, and debris. It can damage the sensor and cause more problems if you use a brush or a complicated tool.
You can do tasks efficiently by watching the following video.
Inspection of physical damage
You should inspect any physical damage and look for signs of wear and tear if the error message still appears after cleaning all the sensors. The sensor must be replaced if it is found to be defective during inspection. There are several critical problems that can be caused by using a defective component.
Checking electrical components
Look for signs of wear and damage on electrical components such as fuses and dashboard bulbs. Replace faulty fuses or bulbs as soon as possible. If you are concerned about electrical connections or wiring, you should inspect them for damage.
Battery Replacement
The battery should be fully charged and functioning properly after it has been analyzed for its condition.
The SCBS unit in the Mazda vehicle may trigger the SCBS inspection required warning light if the battery is weak, low voltage, or too old, so it is imperative that you replace it immediately.
System Reset
The issue may be resolved by resetting the system without the need to dig deep into the structure. The task of resetting your computer can be done efficiently by yourself. The engine of your Mazda should be turned off for a few minutes, and you should wait for about half an hour before you start the engine again. The smart city brake support (SCBS) light can be fixed with this simple reset.
Mechanical Inspection
You should take your Mazda vehicle to the nearest dealership or expert mechanic shop if the message still appears after trying all the above solutions.
Their specialized tools, such as error code scanners, will help them to pinpoint the exact location of the problem. Upon identifying the problems, the certified technician will resolve them.
