Test Drive: After resetting the system, take your car for a test drive to ensure the ABS light remains off and that the braking system functions properly.

Is it OK to drive with ABS light on?

In general, you can still continue driving even if your car’s ABS light is on. This is because your car’s brakes still function as usual and can still slow your vehicle down. However, your car’s tires are at risk of getting locked under heavy braking and that limits your maneuverability in emergencies.


Driving with the ABS light on is not recommended, as it indicates a potential problem with your vehicle’s braking system. The ABS light illuminates when the system detects a fault, which could compromise your ability to brake safely, especially in emergency situations or adverse driving conditions.


While your vehicle may still be operable with the ABS light on, you’ll be relying solely on conventional braking mechanisms. This means your vehicle may be more prone to wheel lock-up during hard braking, leading to longer stopping distances and increased risk of loss of control.


Continuing to drive with the ABS light on also poses the risk of exacerbating the underlying issue, potentially causing further damage to the braking system and leading to more costly repairs down the line.

What causes ABS light on car?

The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.


Several factors can trigger the ABS light to illuminate on a car’s dashboard, indicating potential issues with the Anti-lock Braking System (ABS). Common causes include:


Low Brake Fluid: Insufficient brake fluid in the reservoir can lead to decreased hydraulic pressure, triggering the ABS light.


Faulty ABS Sensors: ABS sensors, located near each wheel, monitor wheel speed. Damage, corrosion, or sensor malfunctions can disrupt their operation and prompt the ABS light to turn on.


Wiring Issues: Damaged or corroded wiring connecting the ABS sensors to the vehicle’s computer system can interfere with signal transmission and cause the ABS light to illuminate.


ABS Module Problems: Issues within the ABS control module, such as electronic failures or internal malfunctions, can lead to ABS light activation.


Wheel Bearing Problems: Faulty wheel bearings can cause erratic wheel speed readings, triggering the ABS light.


Other Brake System Faults: Problems with components like the brake master cylinder, brake calipers, or brake pads can indirectly affect ABS function and activate the ABS light.

How do you check ABS light?

Without a scan tool capable of reading ABS codes, a visual inspection is the easiest thing to do when diagnosing an ABS light. ABS sensor wiring can be inspected from underneath a vehicle that is safely supported on ramps — you may not even need to take the wheels off.


Checking the ABS light involves a systematic process to identify potential issues with your car’s Anti-lock Braking System. Start by visually inspecting the dashboard to confirm if the ABS warning light is illuminated. If it is, the next step is to check the brake fluid level in the reservoir, ensuring it meets the recommended levels.


Proceed to inspect the ABS sensors, located near each wheel, for any visible damage or corrosion. Clean off any dirt or debris that may be obstructing these sensors. If the ABS light persists, consider using an OBD-II scanner to retrieve error codes stored in the vehicle’s computer system. Connect the scanner to the OBD-II port, typically located beneath the dashboard, and follow the instructions to retrieve ABS-related codes.

Can rain cause ABS light to come on?

Water in sensors, aquaplaning etc COULD cause ABS to get confused. Water in induction or sensors can cause limp mode. ABS and traction control lights both take signals from wheel rotation usually wheel too slow ABS and too fast traction control.

Rain itself typically doesn’t cause the ABS light to come on in most vehicles. However, driving in wet conditions can sometimes exacerbate pre-existing issues within the ABS system, leading to the illumination of the ABS light.


One common scenario is water intrusion into the ABS sensors or their wiring harnesses. If these components are already damaged or corroded, moisture from rain can further compromise their functionality, resulting in erratic sensor readings and triggering the ABS warning light.


Additionally, driving through deep puddles or flooded areas can potentially damage the ABS sensors or disrupt their connection to the vehicle’s electronic control unit (ECU), leading to ABS malfunctions.

What Colour is the ABS light?

There is an ABS light on a car dashboard in most vehicles equipped with this braking system. The light is typically yellow, orange, or amber, and it illuminates as part of a system check any time a car with ABS is turned on.


The Anti-lock Braking System (ABS) light typically illuminates in a distinct color to catch the driver’s attention and convey the urgency of addressing potential braking system issues. In most vehicles, the ABS light is displayed in a bright yellow or amber color on the dashboard. This color is chosen for its visibility and contrast against other dashboard indicators, making it easily noticeable even during daytime driving.


The choice of yellow or amber for the ABS light aligns with automotive industry standards, ensuring consistency across different vehicle makes and models. When the ABS light comes on, it serves as a warning signal to the driver that there may be a problem with the ABS system, such as a malfunctioning sensor or low brake fluid levels. Prompt attention to the ABS light is crucial for maintaining safe braking performance and preventing potential accidents on the road.

Can a flat tire cause ABS light?

When the tire went flat, the ABS detected an inappropriate speed for that wheel and illuminated the light to tell you “something’s wrong”. Once you have repaired the flat tire or installed a new tire of the correct size, the ABS light should eventually go out.


A flat tire itself typically doesn’t directly cause the ABS light to illuminate. However, if the flat tire leads to a significant difference in wheel speed compared to the other tires. It can trigger the ABS system to engage erroneously, which may result in the ABS light coming on.


The ABS relies on sensors at each wheel to monitor their individual speeds. If one wheel is spinning significantly slower or not at all due to a flat tire. The ABS may interpret this as wheel slippage or a potential loss of traction, prompting it to activate. This activation could trigger the ABS light to illuminate on the dashboard.

Why is the ABS light on but brakes work fine?

Firstly, understand that the ABS light being on DOES NOT mean that you don’t/won’t have brakes, but it means there’s a problem with the ABS portion/feature of the braking system. A very possible cause could be faulty wheel speed sensors and/or the connections involved with them.


When the ABS light is on but the brakes are working fine. It typically indicates a malfunction in the Anti-lock Braking System’s monitoring or control system rather than an immediate issue with the brakes themselves. The ABS light serves as a warning that the ABS system may not be functioning properly. Potentially compromising its ability to prevent wheel lockup during hard braking.
