C1620 on Hyundai
Active Yaw / Stability Control System Fault
C1620 on Hyundai vehicles indicates active yaw / stability control system fault. Au7o has documented this code across 1 Hyundai model — most commonly on Veloster. C1620 is a manufacturer-specific chassis code (documented on Mitsubishi) associated with the Active Yaw Control / stability control system. That system manages torque distribution and braking inputs to keep the vehicle stable during cornering and on slippery surfaces. When the module detects a fault in this circuit or a related sensor, it disables active yaw/stability control and illuminates the ABS and stability warning lights. Exact meaning varies by maker, so verify against the factory service manual. Typical repair costs on Hyundai range from $200 to $1,800, depending on the specific model and root cause.
Common Causes of C1620
- •Faulty yaw rate sensor
- •Fault in the active yaw control hydraulic/actuator unit
- •Damaged wiring or connectors in the system
- •Related wheel speed or steering angle sensor fault
- •Low system voltage or poor ground
- •Stability control module fault

- Forward Collision-Avoidance / Driver Assistance False Warnings and Camera-Radar Malfunctions2019-2021
Owners have documented intermittent failures of the forward collision warning, lane-keeping, and related ADAS functions, including dashboard messages that the front camera or safety systems are unavailable. Some complaints involve false alerts in clear weather, while others describe the systems disabling themselves after startup or while driving. These issues are often linked to camera alignment, sensor contamination, software logic, or wiring/connectivity problems rather than a mechanical brake fault.
