LAND ROVER B — Body

Extension pad seat motor sensor

Brand: LAND ROVER
Type: B — Body
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Damaged or failed extension pad position sensor (potentiometer/Hall sensor)
  • Open/short or high resistance in sensor wiring or connector
  • Corroded/loose connector at the seat motor or control module
  • Faulty extension pad motor with internal sensor failure
  • Mechanical binding or obstruction preventing full travel
  • Faulty seat control/module or software anomaly

Symptoms

  • Extension pad (thigh support) does not move or only moves intermittently
  • Seat position memory may fail to set or recall extension pad position
  • Visible/ audible abnormal motor behavior (stalling, clicking)
  • Interior message or stored fault codes related to seat module

What to check

  • Read all stored DTCs and freeze frame data from seat/separate modules; note any related seat codes
  • Perform a visual inspection of the seat underside and wiring harness for damage, pinch points, or corrosion
  • Check connectors at the motor and seat control module for corrosion, water, or loose pins
  • Attempt to operate extension pad from each control position and from a diagnostic scanner (command motor)
  • Measure supply voltage (battery +) and ground at the motor harness while commanding the motor
  • Check sensor output voltage/resistance at the sensor connector while moving the pad (compare to expected signal)

Signal parameters

  • Sensor type: typically potentiometer or Hall-effect position sensor (variable voltage output)
  • Reference voltage: ~5 V reference expected to sensor (varies by manufacturer)
  • Sensor output: varies across travel, typically ~0.5–4.5 V (should change smoothly without jumps)
  • Motor drive: 12 V supply and switched ground when commanded (current draw increases under load)
  • Resistance: if sensor is potentiometer, total resistance often in kΩ range; check manufacturer spec

Diagnostic algorithm

  1. Retrieve and record DTCs and module data; note whether B1063 is current or historic and any related codes.
  2. Inspect: visually check the seat frame, motor, sensor connector, and wiring for physical damage, corrosion, or water ingress.
  3. Verify power/ground: with appropriate safety and immobilizer conditions, measure battery voltage at the motor supply pin and confirm good ground while commanding the motor from a diagnostic tool.
  4. Command test: use a diagnostic scanner to run the seat extension motor and observe behavior, listen for noise, and check for movement.
  5. Sensor output check: backprobe the sensor signal and reference pins while moving the extension pad. Confirm reference voltage present and that signal varies smoothly within expected range (no dropouts or sudden jumps).
  6. Continuity/resistance: with ignition off, measure continuity/resistance of wiring between motor/sensor and seat control module; look for intermittent connections by wiggling harness while observing readings.
  7. Mechanical check: verify extension pad moves freely by hand; remove trim as needed to inspect linkage and motor mounting for binding or foreign objects.
  8. Isolate component: if wiring and power/ground are good but sensor signal is bad, isolate/replace the motor assembly or sensor per service procedures.
  9. Software/Module: if all hardware checks good, check for module software updates or perform module reset/learn procedures as per manufacturer guidance.
  10. After repair or replacement, clear codes and perform full function test and memory learn/seat calibration if required.

Likely causes

  • Connector corrosion or loose terminal at the seat motor or seat module
  • Damaged sensor wiring (pinched at seat frame or torn in door sill area)
  • Failed extension pad position sensor (common with motor assembly wear)

Fault status

⚠️ Status
Seat extension pad motor sensor circuit — invalid/erratic or out-of-range signal detected (requires inspection of sensor, wiring, motor, and seat module).
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
