C1564 on Kia
Vehicle Speed Data Invalid
C1564 on Kia vehicles indicates vehicle speed data invalid. Au7o has documented this code across 1 Kia model — most commonly on K5. C1564 is a manufacturer-specific chassis code (documented on Mitsubishi) set when the module receives abnormal or implausible vehicle-speed signal data. The system compares the incoming speed information for consistency, and repeated invalid values cause it to flag the fault and disable functions that depend on accurate speed. Effects can include disabled stability/traction features and related warning lights. Because this is a manufacturer code, confirm the exact definition against the factory manual.
Common Causes of C1564
- •Faulty wheel/vehicle speed sensor
- •Implausible or noisy speed signal on the network
- •Damaged wiring or connectors
- •Communication fault between modules
- •Low system voltage or poor ground
- •Control module fault

Kia K5(1 issue)
- ADAS Sensor Calibration Faults (Lane Keep, Forward Collision)2021-2025
The Advanced Driver Assistance Systems on the K5 — including Lane Keep Assist, Forward Collision Avoidance, and Blind Spot Monitoring — intermittently throw calibration faults and disable themselves. The forward-facing camera behind the windshield and radar sensor in the front bumper are sensitive to windshield contamination, extreme temperatures, and minor front-end impacts. After a windshield replacement, the ADAS sensors require recalibration that many glass shops skip or perform incorrectly.
