ABS and ESP Warning Lights On Together – Common Causes Explained

Seeing ABS and ESP warning lights on together is a common issue in modern vehicles. These systems are closely linked and often rely on shared sensors and control modules.

Common Causes
• Wheel speed sensor faults
• ABS control module communication errors
• Voltage issues after battery replacement
• Steering angle sensor data problems

Symptoms You May Experience
• Stability control disabled
• ABS function unavailable
• Warning lights appearing after starting or driving

Why Both Lights Appear
ABS and ESP systems constantly exchange data. If one system detects unreliable information, both warnings may appear as a safety precaution.
Early diagnosis helps determine whether the issue is sensor-related or module-related.
