Seats memory

Product Overview (JLR OEM‑Spec Interior‑Comfort Retrofit)

Seats memory delivers genuine OEM multi‑profile seating‑preset functionality for DOIP‑based JLR Defender L663 vehicles. However, many mid‑trim Defender models are fitted with full power‑adjustable front seats but omit door‑mount memory‑switch hardware and factory‑enabled memory‑profile logic. As a result, every driver must manually readjust seat height, cushion offset and backrest recline after a driver swap. If you aim to assemble a full premium‑seating comfort package, pair this retrofit with our Heated and Cooled front seats. It unites climate‑controlled seating with saved memory driving positions. This kit supplies genuine OEM door‑card M1/M2/M3 memory‑switch pack and supplementary LIN‑bus wiring pigtails. In turn, it unlocks multiple seat‑position presets, one‑touch recall and smart‑fob‑linked profile synchronisation managed by the DSM and PSM seat‑control‑modules.

First of all, multi‑profile seat‑memory behaviour will never activate by installing memory‑switch hardware alone. Next, technicians remove front door‑card trim panels to fit the OEM M1/M2/M3 memory‑switch assemblies. They also route dedicated LIN‑bus communication wiring and verify all connector locking. After that, our jlrcoding team completes a comprehensive DOIP diagnostic scan. We enable seats‑memory feature flags within the vehicle CCF configuration file. Furthermore, we perform multi‑parameter adaptation for DSM driver‑seat‑module, PSM passenger‑seat‑module, SAM and BCM modules. Once coding finishes, the system reads seat‑position sensor data and stores custom user presets. Meanwhile, it also supports profile binding to individual smart‑fobs for automatic position recall. For this reason, check our Add additional key fob if you want multiple fobs assigned to different driver memory profiles.

Hardware & Operating Logic

This retrofit provides OEM door‑mount memory‑switch packs, LIN‑bus wiring looms, vehicle‑specific pigtails and all required mounting fasteners. The DSM and PSM process Hall‑effect position‑sensor readings for each power‑seat adjustment axis. Subsequently, preset‑storage and recall status signals travel over LIN‑bus and CAN‑FD bus toward SAM and BCM modules. Users save preferred seating positions by pressing the memory button plus one of the numbered preset keys. Once a preset is selected, the seat actuators automatically move to the stored height, fore‑aft and recline coordinates. On compatible configurations, the system triggers automatic seat adjustment when a paired smart‑fob unlocks the vehicle. All seat‑memory storage and recall logic strictly complies with original JLR factory specifications. Notably, non‑volatile module memory retains saved presets through ignition‑off and 12V battery cycles. Even so, preset‑storage and key‑link functions remain dormant after purely mechanical hardware fitment. Rather, they require authorised DOIP multi‑module programming plus seat‑position‑sensor relearn calibration to operate correctly. Finally, you can combine this seating‑comfort upgrade with Heated steering wheel for fully synchronised driver comfort settings.

Vehicle Eligibility & Technical Pre‑Conditions

This Seats memory retrofit suits 2020+ Defender L663 90, 110 and 130 models. The vehicle must be fitted with fully motor‑driven power front seats and compatible DSM‑PSM LIN‑bus seat‑module architecture. Therefore, submit your VIN number first. We inspect existing DSM, PSM, SAM and BCM firmware revisions before starting door‑card disassembly work.

Local work includes partial front door‑card trim removal for driver and passenger doors. Technicians install memory‑switch packs and route LIN‑bus harness connections. In some cases, base‑level vehicles require supplementary wiring upgrades to satisfy JLR seat‑module communication requirements. When hardware installation finishes, we create a secure backup of your original CCF file. We activate the seats‑memory feature flags. Then we execute seat‑position‑sensor relearn, preset‑storage parameter tuning and smart‑fob‑profile‑link setup. Last of all, we clear all seat‑system‑related DTC fault codes.

You can pair local fitting with our worldwide remote coding service. Remote sessions require a DOIP‑VCI or Enet Type‑C cable. In short, follow the standard jlrcoding remote‑service workflow.

Key Technical & Practical Benefits

• OEM Multi‑Profile Seat‑Memory Presets: Genuine JLR memory‑switch hardware stores multiple custom seating positions for fast one‑touch recall when drivers swap vehicles.
• Smart‑Fob‑Linked Profile Synchronisation: Assign each memory preset to an individual smart‑key fob for automatic seat positioning on vehicle unlock.
• Native LIN‑bus / CAN‑FD Multi‑Module Integration: DSM, PSM, SAM and BCM communicate following factory JLR interior‑system logic; no third‑party aftermarket seat‑controller boxes needed.
• Professional DOIP Seat‑System Calibration: CCF feature‑flag activation plus position‑sensor relearn removes seat‑related DTC faults and preserves stable cross‑module‑bus communication.

Quality Assurance & Service Notes

Every retrofit starts with pre‑install diagnostic health‑check and original CCF backup. After coding completes, we verify preset‑save behaviour, one‑touch recall accuracy and smart‑fob‑profile‑link performance. Importantly, hardware‑only memory‑switch installation cannot deliver fully‑compliant factory Seats memory functionality.

Otherwise, incomplete adaptation or mis‑calibrated position sensors produce inaccurate seat‑recall movements or lost stored presets. It may also trigger persistent seat‑system DTC fault codes. Ultimately, once fully calibrated, this OEM‑spec upgrade greatly improves day‑to‑day cabin convenience. It works well for family‑shared vehicles, daily commuters and Defender overland‑focused owners.
