Seat Driver Memory Position Error

Causes
- Faulty seat position (height/recline/track) sensor
- Defective driver memory module or seat control module
- Broken or intermittent wiring or connector (power, ground, signal)
- Corroded or poor ground at seat or module
- Failed memory switch or control input
- Loss of vehicle bus communication (CAN/LIN) to seat module
Symptoms
- Seat memory fails to store or recall driver position
- Seat moves to incorrect position when memory is activated
- No movement when memory button pressed
- Intermittent operation of memory position
- Possible dash message or indicator related to seat memory
- Other seat functions (adjustments) may operate normally or erratically
What to check
- Retrieve freeze frame and module data — note conditions when code set
- Visual inspection of seat connectors (base), wiring harness and grounds
- Check fuses and power/ground at seat control module
- Operate memory switches while monitoring actuator and sensor signals
- Scan for additional codes from seat module, BCM, or network for communication faults
- Check for recent battery disconnects, module replacements, or software updates
Signal parameters
- Seat position sensor voltage/range (typically 0–5 V for potentiometer or digital counts for encoder)
- Actuator motor current draw (amps) during movement
- Memory switch input states (digital on/off)
- Module supply voltage (ignition and battery feed)
- Module ground resistance
- CAN/LIN message presence and IDs for seat module
Diagnostic algorithm
- With a scan tool, read all related modules and note freeze frame, occurrence count, and any related codes (seat module, BCM, network).
- Verify battery voltage is within specification. Check relevant fuses and power feeds to seat control module.
- Inspect harness and connectors at seat base and seat control module for corrosion, damaged wires, or loose pins; repair as needed.
- Check ground continuity from seat module to chassis. Clean and tighten ground connections.
- With seat in a known position, actuate memory recall and record position sensor values and actuator current. Compare to expected ranges.
- Test memory switches for correct continuity and function. Replace switch if intermittent or open.
- If communication errors present, verify CAN/LIN bus integrity (termination, voltages) and check for other modules introducing bus faults.
- If sensors or actuators fail bench or in-vehicle tests, replace the faulty component and retest.
- If module software or calibration suspected (after module replacement or battery loss), perform required reprogramming or calibration procedure per manufacturer data.
- Clear codes and perform multiple cycles of store/recall to verify repair. Monitor for code return.
Likely causes
- Open or short in seat position sensor harness near the seat (most common)
- Module internal fault preventing EEPROM read/write
- Intermittent connector at seat base (moisture, corrosion)
- Faulty seat actuator causing position feedback mismatch
- Voltage supply problems (blown fuse, weak battery, poor ignition feed)
Fault status
Status
Seat memory module detected invalid or inconsistent position data when attempting to store or recall driver seat position. Event logged and DTC set.
Repair difficulty: Medium
Diagnostic time: 0.5-2 hours
