What it means
A receiving module detected implausible data from seat control module D. Seat position, memory recall or heating/ventilation values fail plausibility checks and are rejected.
How it works
Seat control module D sends seat position and supported memory or comfort-function data over the vehicle network. This code sets when a receiving module finds data from module D implausible; which seat and functions that means depends on the vehicle's configuration.
Common causes
Most likely first.
- Module internal fault or sensor input drift
- Software version mismatch after replacement
- Gateway module routing CAN messages incorrectly
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Scan every module and record freeze-frame details to identify the reporting module and related seat or network faults.
- Determine which seat and functions are assigned to module D and check their operation, including adjustment, memory, heating, or ventilation if equipped.
- Inspect module D's connectors and accessible seat wiring for corrosion, loose pins, damage, or pinching as the seat moves.
- Check the module's power and ground under the manufacturer's procedure, since a poor supply can make seat data unreliable.
- Compare live seat position and status values with actual operation, then verify network communication and module configuration using vehicle-specific service information.
Common fixes
- Secure or clean a loose or corroded connector at seat control module D.
- Repair damaged or pinched wiring or restore the module's power or ground connection.
- Correct software or configuration if the fault followed module replacement or programming.
- Replace seat control module D if its connections, supply, and configuration are correct but it continues to send implausible data.
Can I keep driving?
Driving is generally possible if the affected seat is fixed securely in a safe position. Avoid driving if the seat can shift or will not lock.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
