Lane Keep Assist (LKA)

Technical Overview

LKA relies on data from the forward‑facing stereo camera to detect lane‑line positions. When unintended drift is detected, the ADAS camera controller sends actuation requests to the PSCM power‑steering control module to deliver mild counter‑steering torque; driver input can override this assistance at any time. Feature‑enablement requires coordinated CCF changes across the camera‑control unit, PSCM steering module, instrument‑cluster and BCM gateway to activate HMI menu entries, visual cluster warnings and steering‑torque permissions. This coding workflow reads the original factory CCF dataset, enables LKA feature flags, executes cross‑module integrity validation and writes modified configuration back via OBD‑II connection. Post‑write, controlled ADAS‑module resets plus a full vehicle sleep‑wake cycle are required for menus and actuation logic to take full effect. This is purely software‑based modification; stereo camera and compatible electric steering hardware must already be fitted. Full roll‑back is available restoring the backed‑up original CCF file.

Core Technical Activation Capabilities

• Multi‑block ADAS‑domain CCF‑parameter modification unlocking Lane Keep Assist (LKA) for camera‑and‑PSCM‑equipped JLR vehicles
• Enables corrective steering‑torque intervention, instrument‑cluster visual alerts and infotainment HMI toggle‑menu for LKA functionality
• Pre‑write cross‑module CCF integrity validation preventing incompatible ADAS‑steering‑domain parameter combinations before committing changes to vehicle ECUs
• Complete CCF backup‑restore workflow preserving original factory configuration before applying ADAS‑related configuration changes
• ADAS diagnostic routines: read camera‑module and PSCM DTC faults, verify pre‑activation and post‑activation LKA feature‑flag‑status
• Session‑log generation capturing vehicle VIN, timestamp and modified ADAS‑CCF parameters for internal workshop audit‑trail purposes.

Vehicle, Hardware & System Prerequisites

Critical hardware prerequisites: vehicle must have factory‑fitted functional forward‑facing stereo camera and PSCM electric power‑steering hardware. LKA cannot be activated via coding alone if either component is missing or faulty. Supported MY2015‑2025 Range Rover, Range Rover Sport, Defender, Discovery, Velar, Evoque and full Jaguar passenger‑car ranges. Host‑system requirement: Windows 10 / Windows 11 64‑bit PC with valid SX‑TOOL software licence. Use J2534 pass‑through adapters for older CAN‑bus vehicles or Enet‑WiFi / Type‑C Enet‑cable hardware for DoIP‑platform vehicles. Stable regulated 12 V battery supply is mandatory for CCF‑write cycles and module resets. Some late‑model secure‑gateway‑protected vehicles may require supplementary online authorisation for ADAS‑domain‑configuration‑writes. Important note: LKA is a driver‑assist aid and never replaces attentive driver steering responsibility.
