Don't ignore this dash warning — ABS light explained
Jun 27, 2025 5:26 pm
Hi ,
Has your ABS light ever come on while driving and left you wondering what it means — or worse, how much it’s going to cost to repair?
The Anti-lock Braking System (ABS) is critical to your vehicle’s safety, and when the warning light appears, it’s not something to ignore. But don’t worry — most causes are simple to identify with the right tools.
Common Reasons Your ABS Light Is On:
1️⃣ Faulty wheel speed sensors
These sensors monitor the number of rotations of each wheel — if one fails, the system can't respond properly during braking.
2️⃣ Low brake fluid
Your ABS system needs adequate hydraulic pressure to function. A low reservoir can trigger the warning.
3️⃣ Malfunctioning ABS control module
This is the brain of the system. If it fails, the ABS light will stay on, and the system may be disabled.
The ABS light can turn on for various reasons, and it can be hard to find the cause without a little help.
How can you tell what the right reason is? Before you start checking every sensor on your car, scan it with a scanner like the YOUCANIC Full-System Scanner.
Not only can the YOUCANIC scanner read and clear fault codes in the ABS system, but it can also scan your SRS/airbag system and your Electronic Control Unit (ECU)!
