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

Seats memory delivers genuine OEM multi‑position driver‑seat memory functionality for DOIP‑based JLR Defender L663 vehicles. Many mid‑trim vehicles come with fully‑functional power‑adjustable seats but lack memory‑switch hardware.

Even after installing memory‑switch packs, locked CCF feature flags disable preset‑storage, mirror‑sync and easy‑entry‑exit routines. Drivers need to manually readjust seat and mirror positions for every different user. Pair this retrofit with our Heated front seats for combined heating and memory‑preset cabin comfort.

Our kit supplies OEM driver‑side memory‑switch assembly and LIN‑bus wiring pigtails. It unlocks up‑to‑three user seat presets, side‑mirror memory synchronisation and easy‑entry‑exit function following JLR factory L663 specifications.

Hardware Installation & DOIP Coding Workflow

Full seats‑memory functionality cannot activate by hardware swap alone. Technicians perform partial driver‑door‑card disassembly. They fit genuine memory‑switch pack and secure DSM seat‑module LIN‑bus electrical connectors.

Our jlrcoding team completes a full DOIP diagnostic scan. We enable seats‑memory CCF feature flags. Multi‑parameter adaptation runs for DSM, BCM, GWM, KVM and IAM modules.

After coding finishes, DSM stores calibrated seat‑position values inside non‑volatile memory. Memory‑preset controls become operational. Check our Add additional key fob to link different smart‑fobs to individual driver memory‑profiles.

Hardware & Operating Logic

This retrofit includes OEM memory‑switch pack, LIN‑bus wiring looms, vehicle‑specific pigtails and mounting fasteners. The DSM driver‑seat‑module reads hall‑effect position‑sensor data for seat cushion, backrest and side‑mirror coordinates.

Memory‑profile status, position‑sensor telemetry and diagnostic DTC data transmit over LIN‑bus and CAN‑FD bus toward BCM, GWM, KVM and IAM modules. Users store up‑to‑three independent driver presets via door‑mounted switches.

Easy‑entry‑exit automatically shifts the seat rearwards for simpler vehicle ingress and egress. Memory profiles can bind to authenticated smart‑key fobs for automatic position recall. Pure mechanical memory‑switch fitment leaves preset‑storage and mirror‑sync logic inactive. Authorised DOIP programming plus seat‑position‑sensor relearn calibration is mandatory. Combine this comfort upgrade with Configurable Ambient Interior Lighting to complete personalised cabin‑environment setup.

Vehicle Eligibility & Technical Pre‑Conditions

This retrofit suits 2020+ Defender L663 90, 110 and 130 DOIP‑architecture models. Your vehicle must already have fully‑functional power‑adjustable driver seat with integrated position‑sensors within DSM module. Submit your VIN number for firmware revision pre‑check.

Workshop tasks include driver‑door‑card trim removal, memory‑switch installation and LIN‑bus harness‑connection validation. Some base‑trim vehicles need supplementary LIN‑bus wiring upgrades. After hardware installation we create secure backup of your original CCF configuration file.

We activate feature flags, run seat‑position‑sensor relearn calibration and tune easy‑entry‑exit movement‑threshold parameters. All seat‑comfort‑related DTC fault codes get cleared. Remote coding service is available with DOIP‑VCI or Enet Type‑C cable.

Key Technical & Practical Benefits

• OEM Multi‑Position Driver‑Seat Memory Presets: Genuine JLR DSM‑managed memory stores up‑to‑three driver seat positions for quick one‑touch recall between different vehicle operators.
• Mirror‑Memory Sync & Easy‑Entry‑Exit: Side‑mirror positions save together with seat presets; easy‑entry‑exit automatically moves seat rearwards to assist getting‑in and getting‑out.
• Native LIN‑bus / CAN‑FD Multi‑Module Integration: DSM communicates with BCM, GWM, KVM and IAM following factory JLR seat‑comfort‑system‑logic; supports smart‑fob‑linked memory‑profile recall, no aftermarket control‑boxes required.
• Professional DOIP Seat‑Memory‑System Calibration: CCF feature‑flag activation plus position‑sensor relearn clears seat‑comfort‑related DTC faults and guarantees stable cross‑module‑bus communication.

Quality Assurance & Service Notes

Every retrofit starts with pre‑install diagnostic health‑check and original CCF backup. After coding, we verify memory‑preset storage‑recall, mirror‑sync behaviour and easy‑entry‑exit movement performance.

Important: Hardware‑only memory‑switch fitment cannot achieve full factory Seats memory functionality.

Incomplete adaptation or mis‑calibrated position‑sensor parameters can produce failed preset‑saving, erratic seat‑movement or persistent seat‑comfort‑related DTC faults. Once fully calibrated, this OEM‑spec comfort upgrade simplifies driver‑profile switching. It works well for multi‑driver family‑vehicles, fleet‑use Defender units and overland‑focused owners.
