U0547: Invalid Data Received From Seat Control Module E

What it means

A receiving module detected implausible data from seat control module E. Seat position, memory recall or heating/ventilation values fail plausibility checks and are rejected.

How it works

Seat control module E manages the seat functions assigned to it, such as position, memory recall, or heating and ventilation. Other modules check its reported states for plausibility; this code sets when data from module E fails those checks and is rejected.

Common causes

Most likely first.

1. Module internal fault or sensor input drift
2. Software version mismatch after replacement
3. 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

1. Scan all modules and save freeze-frame and communication details to identify which recipient logged U0547 and whether position, memory, heating, or ventilation data from module E was rejected.
2. Check live data for module E while operating the affected seat functions, and compare reported position or operating state with the seat's actual movement and response.
3. Inspect the seat controls, connectors, and wiring to module E for damage, loose pins, or corrosion, taking care around under-seat wiring.
4. Check service history for a seat-module or seat-component replacement or software update that may have left module E incorrectly configured.
5. Use network diagnostics to check CAN communication and gateway routing for module E, then test its position and comfort-function inputs according to the manufacturer's procedures.

Common fixes

• Reconnect loose seat-module connectors and repair damaged or corroded wiring.
• Correct module E configuration after a seat or module replacement.
• Repair or replace a faulty seat-position sensor or comfort-function input if testing identifies it.
• Repair or replace the affected seat actuator or heating or ventilation component if it is causing invalid data.
• Repair or replace seat control module E if its reports remain implausible with valid inputs.

Can I keep driving?

The seat functions assigned to module E, including position adjustment or memory, may be unavailable or unreliable. Set the seat securely before driving and avoid adjusting it while the vehicle is moving.
