U0562 indicates that the vehicle's control network has detected invalid or missing data from the Seat Control Switch Module B. This usually points to a communication problem between the module and the body control module (or related gateway).
The module may have internal failure causing it to send corrupted or no data on the communication bus.
Corrosion, chafed wires, or loose pins can corrupt the CAN/LIN signal, leading to invalid data detection.
Loss of voltage or poor ground can cause the module to reset or transmit garbled data.
If the BCM cannot properly receive or interpret messages, it may set U0562, though this is less common than a module fault.
Rarely, a corrupted software state can misinterpret valid data as invalid; usually resolved by reprogramming.
The powertrain control module is seldom the cause; replacement is rarely needed for this code.
No. The PCM is rarely at fault for this code; the issue is almost always in the seat control switch module B, its wiring, or power/ground.
Yes. If the fuse supplying power to module B is open, the module may lose power and send invalid data, triggering the code.
Usually not. The module is plug‑and‑play; however, if the vehicle stores calibration data, a dealer‑level reset may be recommended.
Clearing only removes the symptom; if the underlying fault remains, the code will return.
