L663 Electrically deployable side steps

Product Technical Overview

First, many L663 Defender 110 variants leave factory without electrically deployable side‑step hardware. Even after completing all mechanical installation and wiring, automatic door‑triggered deployment, obstacle‑detection and Pivi‑Pro menu control will remain non‑functional. Instead, the vehicle will store persistent DTC faults within RBM, BCM and CAN‑gateway modules. For instance, you may observe no motor movement on door‑open trigger. You may trigger configuration‑mismatch fault‑codes such as U1A40‑00. Therefore, this retrofit strictly follows official JLR TOPIX accessory fitting documentation. It uses heavy‑duty chequered anti‑slip tread surfaces with obstruction‑detection safety logic, stows flush under vehicle sills when not in‑use. It also includes OEM‑pin‑matched sealed CAN‑bus harness and variant‑specific under‑body shielding parts. In addition, chassis mounting‑points are pre‑existing; no irreversible body‑shell cutting required during fitment.

Next, full electrically deployable side‑step functionality requires authenticated DoIP‑capable diagnostic hardware. Suitable tools include JLR Enet, JET Pro or Pathfinder software. After physical fitment, several mandatory diagnostic tasks must be performed. To begin, edit CCF parameters to enable deployable‑running‑board feature‑flags. Then execute RBM control‑module configuration and CAN‑gateway node‑recognition service routine. Following that, perform full deploy‑stow cycle testing plus obstacle‑detection validation. Finally, clear all retrofit‑related DTC entries. As an option, JLR‑Decoder offers on‑site configuration support. We also provide worldwide remote VIN‑based activation service.

Key Technical Specifications

• Vehicle Compatibility: Defender L663 110 only, 2020‑2026 DoIP secure‑gateway. Supports LHD and RHD variants. Not compatible with Defender 90 /130, fixed side‑steps or bright side‑tube accessories.
• Hardware Scope: OEM LH / RH motor‑driven deployable side‑step assemblies, VPLET0278 RBM running‑board‑control‑module, CAN‑bus wiring harness, chassis mounting brackets, dedicated undershield and torque‑rated fasteners.
• Mandatory Diagnostic Procedures: Enable deployable‑side‑step CCF feature flags. Execute RBM‑module configuration and CAN‑gateway node‑recognition. Validate door‑trigger deploy‑stow cycles and obstacle‑detection. Scan and erase all stored DTCs afterward.
• Enabled Factory Functions: Automatic deploy‑on‑door‑open, stow‑on‑door‑closed. Obstacle‑detection safety reversal. Pivi‑Pro infotainment menu for manual override. Rated 270 kg static‑load per‑side; fitment reduces nominal off‑road ground‑clearance.
• Electrical Interface: 12 V vehicle power supply. CAN‑body bus communication network, OEM sealed pin‑compatible connectors.
• Deliverables: OEM Electrically Deployable Side Steps hardware set. TOPIX‑aligned accessory fitting procedure. Access to TEC‑DOC exterior‑system interactive wiring diagrams.

JLR‑Compliant 3‑Stage Retrofit Workflow

1. VIN Pre‑Validation: First, submit your 17‑digit VIN to our JLR‑Decoder VIN‑Decoder tool. This step checks factory‑option build‑data, chassis wheelbase and existing exterior‑accessory fitment status. As a result, you confirm full compatibility before you place your order. Defender 90, 130 and vehicles fitted with fixed side‑steps cannot use this kit.
2. Physical Hardware Installation: Start by disconnecting the 12V battery following TOPIX safety guidance. Raise vehicle on rated two‑post lift. Fit main step assemblies, mounting brackets and RBM control‑module. Route and secure dedicated CAN‑bus harness, install protective undershield components. Reconnect vehicle battery after full mechanical assembly completes.
3. DoIP Diagnostic Activation & Validation: Connect your authenticated DoIP VCI interface. To start, edit CCF and activate deployable‑running‑board feature parameters. After that, run RBM‑module configuration plus CAN‑gateway node‑recognition service routine. Then execute complete deploy‑stow cycle and obstacle‑detection functional‑test. Once finished, clear all retrofit‑generated DTCs. In the end, verify Pivi‑Pro side‑step control‑menu via TEC‑DOC functional‑test procedures.

Important Technical Notes & Limitations

Pure software‑only activation cannot add deployable‑side‑step functionality to base‑spec vehicles. You must install physical step assemblies, RBM control‑module and complete OEM CAN‑bus harness. Once you finish the retrofit, run a complete module scan. Use our JLR‑Decoder DTC library to check for CAN‑bus configuration fault‑codes. If RBM node‑recognition fails, motor‑deployment and safety‑detection functions remain inactive. Furthermore, this product supplies electrically deployable side‑steps hardware only. Fitment reduces off‑road ground‑clearance and articulation capability. Fixed‑step or side‑tube components are sold separately.
