Code U0247 indicates that the vehicle's primary communication network has lost contact with the Seat Control Module F. This typically means the module is not responding to messages on the CAN or LIN bus, resulting in a loss of electronic seat functions.
Wires beneath the seat can become chafed, pinched, or broken due to the repeated movement of the seat.
Moisture or debris entering the connectors under the seat can cause poor electrical contact or signal interruption.
A blown fuse powering the Seat Control Module F will cause the module to shut down and stop communicating.
Internal hardware failure within the module itself can prevent it from sending or receiving network data.
A failure in the vehicle's central gateway module may prevent communication between different network segments.
A failure in the engine computer is highly unlikely to cause this specific code but is theoretically possible if the gateway is integrated.
No. It is extremely rare for the PCM to be the cause of a seat communication error; the fault is almost always located in the seat's own wiring or the seat module itself.
Because the seat slides forward and backward, the wires are subject to constant flexing and friction against the seat frame, leading to insulation wear and broken conductors.
Not necessarily. If the issue is a broken wire or a blown fuse, a new module will not resolve the communication failure.
