COMPATIBILITY

Confirmed applications for the AH22-14C249-AA module family include:

• Land Rover Discovery 4 / LR4 L319 – approximately 2009–2013

• Range Rover Sport L320 – approximately 2009–2013

Discovery 4 applications include vehicles fitted with compatible electrically adjustable driver memory seats.

Depending on vehicle specification, applications can include:

• 2.7 TDV6 diesel

• 3.0 TDV6 diesel

• 3.0 SDV6 diesel

• 5.0 V8 petrol

Engine size itself does not determine compatibility. Seat specification, electrical equipment, module hardware/software version and vehicle configuration are more important.

TECHNICAL INFORMATION

The seat control module receives commands from the electric seat adjustment controls and manages operation of the relevant seat motors and memory functions.

Depending on vehicle specification, the seat system can control functions including:

• Seat forward / backward adjustment

• Seat height adjustment

• Seat base angle adjustment

• Backrest adjustment

• Driver seat memory functions

• Associated seat-position functions

• Communication with other vehicle comfort systems

The module forms part of the vehicle’s electronic network and communicates with other control systems.

MEMORY SEAT SYSTEM

AH22-14C249-AA is associated with the driver’s electric memory seat system.

The memory system allows stored seat positions to be recalled on appropriately equipped vehicles. Because Discovery 4 models were available with several different seat specifications, this module should not be assumed to fit every electrically adjustable seat.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

• Driver electric seat completely inoperative

• One or more seat adjustment functions not working

• Memory seat functions not operating correctly

• Seat motors work intermittently

• Stored seat positions cannot be recalled

• Communication fault with the seat control module

• Diagnostic fault codes relating to the driver seat module

• Water or electrical damage to the original ECU

• Replacement required following seat or wiring repair

IMPORTANT DIAGNOSTIC INFORMATION

A non-working electric seat does not necessarily mean the seat ECU has failed.

Before replacing the module, check:

• Seat fuses and power supply

• Earth connections

• Wiring underneath the seat

• Electrical connectors

• Seat adjustment switch

• Individual seat motors

• CAN communication

• Diagnostic fault codes

Wiring and connectors underneath electrically adjustable seats can also cause intermittent faults.

PROGRAMMING / CODING

A replacement seat module may require configuration/programming, depending on the donor module, vehicle specification and software level.

Where necessary, configuration should be performed using suitable Land Rover/JLR diagnostic equipment.

For this reason, we do not guarantee that a used module will be completely plug-and-play in every vehicle.

INSTALLATION

Disconnect the vehicle battery correctly before removing or disconnecting the front seat or its electronic components.

The front seat contains SRS/airbag-related wiring and components, so correct workshop procedures should be followed.

After installation, check all seat adjustment and memory functions and carry out diagnostic configuration if required.

IMPORTANT COMPATIBILITY NOTE

Please match the number on your original module before purchasing.

The safest match is:

AH22-14C249-AA

Also compare:

• Hardware number

• Software/reference numbers

• Electrical connectors

• Seat specification

• Memory-seat equipment

• Vehicle VIN / configuration

Numbers such as LR019377, LR019562, LR021530 and LR025958 are associated with this module family, but supersessions and software/configuration differences can exist.

Do not purchase solely by model, year or engine size.
