A powered seat may still move even when its memory function no longer recalls the correct position. Describe the movement controls and memory buttons separately when reporting the fault: this helps distinguish a lost setting from an electrical or position-control problem.
What the component does
HELLA describes memory seat modules that store and coordinate personal settings such as seat, mirror and steering-wheel position. The exact functions depend on the vehicle equipment. Its seat-control systems can use CAN or LIN communication, so the seat module may form part of a wider comfort network rather than operating entirely alone.
Information that helps an assessment
Record which seat is affected, whether every direction works, whether each stored profile behaves differently and whether mirrors or steering-wheel recall are also affected. Include recent seat removal, battery disconnection, water ingress or software work. Supply the seat module label and diagnostic report if a workshop has already accessed them. Do not unplug under-seat connectors: other wiring there may serve restraint equipment.
Before ordering or removing a unit
A fault message identifies a system to investigate; it does not prove that its control unit needs replacement. Record the complete scan report and component identification before codes are cleared or parts are ordered. Repair suitability depends on the exact unit and the findings from diagnosis.
