Causes
- Open or short in wiring harness to the lumbar actuator
- Corroded/damaged seat connector or pin
- Failed lumbar motor/air pump/actuator
- Faulty seat control module or module software error
- Blown fuse or poor power/ground supply to the seat
- Mechanical obstruction or seized actuator
Symptoms
- Lumbar support on one side of the seat will not move or adjust
- Intermittent lumbar operation or only partial movement
- Audible motor noise without movement or clicking
- Seat system fault stored and related body module warnings
- One-side seating comfort differences (one side stiff)
What to check
- Read and record DTCs and freeze frame data with a diagnostic scanner; note related body/seat codes
- Attempt lumbar adjustment while watching live data to confirm failure and reproducibility
- Visually inspect seat connectors, wiring at seat base and hinge for damage, corrosion or moisture
- Check relevant fuses and power/ground at seat module and actuator connector
- Perform wiggle test of wiring while operating lumbar to reproduce fault
- Measure supply voltage and ground at the lumbar actuator connector when commanded
Signal parameters
- Supply voltage at actuator connector when commanded: ~11–14 V (vehicle battery voltage)
- Ground continuity to chassis:
- Actuator current draw while running: typically in the range of 0.2–5 A (vehicle-specific)
- Actuator resistance at rest: consult vehicle repair manual (varies by actuator type)
- CAN/seat-module message showing lumbar command and feedback (if applicable)
Diagnostic algorithm
- Retrieve all stored codes and related data with a Land Rover-compatible scan tool. Note any additional seat or body network codes.
- With ignition on, attempt to operate the lumbar while watching live data. Confirm which side and whether command is issued from the module.
- Visually inspect the seat harness, connector and pins at the seat base and hinge for corrosion, bent pins or water damage. Repair damaged wiring/connectors.
- Check relevant fuses and verify power and ground at the actuator connector. Repair any power/ground faults.
- Measure actuator resistance with connector disconnected. Compare to specification. If out of spec, bench-test or replace the actuator.
- If voltage and ground are present and actuator is good, check seat control module outputs and CAN messages. Reflash or replace module only after confirming wiring and actuator are good.
- Repair or replace failed components (connector repair, actuator, wiring harness, seat module) as required.
- After repairs, clear codes and perform full function test, cycle lumbar through range, and re-scan to confirm no recurrence.
Likely causes
- Broken or bent pin in the lumbar connector
- Lumbar actuator failure (motor or pump)
- Intermittent connection due to wiring chafe at seat hinge
- Poor ground at seat module or connector
- Faulty seat control module software or module failure
Fault status
Status
Seat lumbar circuit fault detected on seat side. Electrical or functional diagnostic required. Fault stored in body/seat control module.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
