LAND ROVER B — Body

Switch for the seat height

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

Causes

  • Faulty seat height switch (internal contacts worn or stuck)
  • Open or short in wiring harness to switch
  • Corroded, bent or loose connector pins at switch or seat control module
  • Poor ground or power supply to the switch or seat module
  • Water ingress or contamination at switch or connectors
  • Faulty seat control module/software or CAN/BUS communication fault

Symptoms

  • Seat height will not adjust or adjusts intermittently
  • One-direction operation (up or down only) or non-responsive switch
  • DTC stored and illuminated warning/message may appear in instrument cluster or vehicle message system
  • Other seat functions may be affected if shared wiring or module fault present
  • Possible clicking or no motor activity when switching

What to check

  • Retrieve freeze-frame and full fault code list with a scan tool; note any related seat or body module codes
  • Visual inspection of seat switch, harness, connectors and surrounding area for damage, corrosion or water ingress
  • Check relevant fuses and fusible links for the seat system
  • Operate the switch while observing connector and harness for movement or intermittent behaviour (wiggle test)
  • Check for other symptoms or faulty seats (left/right) to narrow wiring vs module

Signal parameters

  • Supply voltage at switch (key ON): approx. battery voltage (~12 V) present on supply pin
  • Ground continuity from switch to chassis ground
  • Switch output: either on/off voltage (near 0 V or battery voltage) or variable/resistive signal depending on design
  • Seat control module input message on vehicle bus (CAN/LIN) for some models — verify communication present
  • Typical switch current very low; motor current much higher (measure at motor if needed)

Diagnostic algorithm

  1. Connect a diagnostic scan tool, read and record B1B95 and any related codes, view live data while operating the seat height switch.
  2. Perform visual inspection: remove trim as needed, inspect switch assembly, wiring harness and connectors for corrosion, broken wires, water intrusion or damage.
  3. Check fuses and power supplies related to seat circuits; restore any blown/loose fuses and retest.
  4. Backprobe the switch connector with ignition ON and operate the switch: verify supply voltage, ground and output signal change. Note whether output is steady, intermittent or absent.
  5. Wiggle harness and connector during operation to check for intermittent connection faults.
  6. If switch output is absent or erratic, remove switch and bench-test or measure continuity across switch contacts; replace switch if faulty.
  7. If switch tests good, trace wiring between switch and seat control module for opens/shorts/poor pins; repair wiring or pins as required.
  8. If wiring checks good, verify communication to seat control module (CAN/LIN) and test module ground/power. Replace or reprogram module only after confirming wiring and switch are good.
  9. Clear codes and verify repair by cycling seat function and confirming code does not return.
  10. After repair, perform final functional test and ensure no other related DTCs are present.

Likely causes

  • Failed/dirty/contaminated seat height switch
  • Damaged wiring or connector at the seat switch (pin corrosion, broken wires)
  • Poor ground or supply to the seat module/switch
  • Water ingress into switch/connector

Fault status

⚠️ Status
B1B95 - Switch for the seat height: Circuit fault detected (open/short/intermittent or no communication). Check switch, wiring and seat control module.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
