The 2022 Honda Accord's Lane Keeping Assist System (LKAS) provides steering assistance to help keep the vehicle centered in its lane. When LKAS won't engage—indicated by the system icon not illuminating or the steering assistance not activating—understanding the system's requirements helps identify the cause.
How LKAS Operates
Honda's LKAS uses the camera mounted behind the windshield to detect lane markings. When enabled and conditions are right, the system provides gentle steering torque to help maintain lane position. The LKAS icon illuminates green when active. The system is designed as an assist, not autonomous steering—it requires driver input and attention.
Requirements for LKAS Engagement
LKAS requires specific conditions to engage. Vehicle speed must be within the operating range (typically 45-90 mph). Lane markings must be clearly visible to the camera. The driver's hands must be on the steering wheel. The system must be enabled via the button on the steering wheel. All conditions must be met simultaneously.
Common Non-Engagement Causes
Several factors prevent LKAS from engaging. Speed outside the operating range is common—the system won't activate in city driving. Faded or missing lane markings prevent detection. Dirty windshield in the camera area blocks visibility. The system being accidentally disabled via the steering wheel button. Curves sharper than the system can handle cause temporary disengagement.
System Disabled vs. Not Engaging
Distinguishing between LKAS being disabled (turned off by button) and not engaging due to conditions helps diagnosis. Check the steering wheel LKAS button state and dashboard indicator to verify the system is enabled before troubleshooting non-engagement.
