COMPATIBILITY

LAND ROVER DISCOVERY 4 / DISCOVERY IV / LR4 L319 – 2010–2016

Suitable for selected Discovery 4 L319 vehicles equipped with the corresponding electrically adjustable front seat.

Potential applications include:

• Discovery 4 2.7 TDV6 – 276DT

• Discovery 4 3.0 TDV6 – 306DT

• Discovery 4 3.0 SDV6 – 306DT

• Discovery 4 3.0 Petrol – selected markets

• Discovery 4 4.0 V6 Petrol – selected markets

• Discovery 4 5.0 V8 Petrol – 508PN

• LR4 North American specification vehicles

Potential trim applications include selected:

• GS

• XS

• SE

• HSE

• HSE Luxury

• Landmark

• Other electric-seat equipped specifications

Engine size is not the primary compatibility factor for this component.

Compatibility depends mainly on the:

• Seat side

• Electric seat specification

• Memory/non-memory configuration

• Number of adjustment functions

• Lumbar equipment

• Adjustable bolster equipment

• Electrical connector

• Switch configuration

• Production/VIN range

2010 DISCOVERY 4 APPLICATION

Land Rover’s factory parts information confirms several driver-seat electrical configurations from the beginning of Discovery 4 L319 production.

These include:

• Electric Front Seat Adjustment – Driver Memory

• Electric Front Seat Adjustment – Driver Memory with Articulated Driver Seat Bolster

• Electric Front Seat Adjustment – Non-Memory

• Driver Power Lumbar Support

This means two 2010 Discovery 4 vehicles can use different seat electrical components even though they are the same model and year.

DRIVER / RIGHT / O/S INFORMATION

This particular switch was removed from the:

DRIVER FRONT SEAT

On a UK RHD Discovery 4:

Front Right = Driver / O/S

For an LHD Discovery 4 / LR4:

Front Left = Driver

Therefore, international buyers should compare the physical seat side, switch configuration and original part number, rather than relying solely on the word “Driver”.

TECHNICAL INFORMATION

The seat adjustment switch acts as the driver’s input control for the powered front-seat mechanism.

When the driver operates one of the controls, the seat electrical system commands the corresponding motor to move the appropriate part of the seat.

Depending on specification, the electric seat can provide:

• Forward / backward adjustment

• Seat height adjustment

• Seat cushion tilt adjustment

• Backrest recline adjustment

• Lumbar adjustment

• Bolster adjustment on equipped vehicles

• Memory-related seat positioning on equipped vehicles

Land Rover documentation specifically identifies backrest, height, cushion tilt and fore/aft adjustment as functions of the Discovery 4 electric front-seat system.

ELECTRIC DRIVER SEAT SYSTEM

The complete system can incorporate:

• Driver seat adjustment switch

• Seat wiring harness

• Individual electric adjustment motors

• Seat drive cables

• Seat adjustment mechanisms

• Driver Seat Module / memory electronics

• Seat position information

• Lumbar components

• Bolster adjustment components

• Vehicle electrical network

Higher-specification Discovery 4 vehicles can additionally have a driver’s seat memory function.

The memory system allows stored seat positions to be recalled and can operate in conjunction with other driver-position settings depending on vehicle equipment.

MEMORY SEAT INFORMATION

On vehicles fitted with driver’s memory, stored seat positions can be recalled using the vehicle’s memory controls.

The seat adjustment switch and seat electronics work together with the individual electric motors to position the seat.

Therefore, when replacing a switch on a memory-equipped vehicle, the replacement should correspond to the original seat specification.

COMMON SYMPTOMS OF A FAULTY SEAT SWITCH

• Driver seat does not adjust

• One adjustment direction not working

• Seat moves in one direction but not the opposite direction

• Backrest adjustment not responding

• Height adjustment not responding

• Cushion tilt not working

• Fore/aft adjustment not working

• Switch operates intermittently

• Switch feels loose

• Broken adjustment button

• Internal electrical contact failure

• Damaged electrical connector

• Switch physically damaged

• Replacement required following seat repair

IMPORTANT DIAGNOSTIC INFORMATION

A non-working electric seat does not automatically mean the adjustment switch is faulty.

Before replacing the switch, check:

• Seat fuses

• Power supply

• Ground connections

• Seat wiring harness

• Switch connector

• Individual seat motors

• Drive cables

• Seat control/memory module

• Mechanical seat mechanisms

• Seat rails

• Stored diagnostic faults where applicable

If only one adjustment function has failed, the problem could be the corresponding:

• Switch contact

• Motor

• Wiring

• Drive cable

• Gearbox

• Mechanical adjuster

Further diagnosis is recommended before replacing components.

SEAT MOTOR CONTROL

The switch operates the seat’s individual adjustment mechanisms.

Depending on specification, the seat can contain separate motors for functions such as:

• Fore/aft movement

• Height adjustment

• Cushion angle/tilt

• Backrest adjustment

The switch therefore needs to have the correct internal electrical configuration for the seat in which it is installed.

DRIVER SEAT MEMORY MODULE

Memory-equipped Discovery 4 vehicles use additional electronics to manage stored seat positions.

For reference, LR025958 is documented as an 8-way driver seat memory control unit for:

• Discovery 4 – 2010–2016

• Range Rover L322 – 2010–2012

• Range Rover Sport L320 – 2010–2013

This demonstrates the wider shared JLR seat-control architecture, but LR025958 is the memory control module, not the adjustment switch being sold here.

ADDITIONAL JLR COMPATIBILITY

Related electric seat switch and control systems are found on:

• Discovery 3 L319

• Discovery 4 L319

• Range Rover Sport L320

• Range Rover L322

However, the seat adjustment switch should not automatically be considered interchangeable across these models without matching the exact engineering/OE number.

Differences can include:

• Left/right configuration

• Memory/non-memory seat

• Number of adjustment functions

• Lumbar controls

• Bolster controls

• Connector arrangement

• Production year

• Software/electrical architecture

For this reason, Discovery 4 L319 remains the primary confirmed application until the exact number from the switch is known.

INSTALLATION

Designed to mount within the corresponding front-seat control/trim assembly.

Before installation compare:

• Original part number

• Electrical connector

• Connector pin arrangement

• Number of adjustment controls

• Switch shape

• Mounting points

• Seat side

• Memory/non-memory specification

• Lumbar/bolster equipment

Care should be taken when removing the surrounding plastic seat trim because the retaining tabs can become brittle with age.

After installation, test every available seat adjustment function through its normal operating range.

PROGRAMMING / CODING

For a like-for-like replacement of the physical seat adjustment switch, programming or coding should not normally be required.

The switch primarily provides adjustment commands to the existing seat electrical/control system.

However, replacement of the driver seat memory/control module is a separate procedure and may require diagnostic configuration depending on the component and vehicle.

IMPORTANT COMPATIBILITY NOTE

Land Rover used different driver-seat configurations on the Discovery 4.

Before ordering, please compare:

• Part number on original switch

• Driver/right-seat application for UK RHD vehicle

• Electrical connector

• Number of pins

• Switch/button arrangement

• Mounting points

• Memory/non-memory specification

• Lumbar equipment

• Bolster equipment

• Vehicle production year/VIN where necessary

Do not purchase solely because your vehicle is a 2010–2016 Discovery 4.

Matching the original switch number and physical/electrical configuration is the safest method of confirming compatibility.
