Adaptive Cruise Control with Stop‑Go Retrofit & OEM Coding | JLR Queue Assist ACC Upgrade
Short Description
Our Adaptive Cruise Control with Stop‑Go service delivers genuine OEM front radar‑sensor hardware installation combined with dealer‑grade DOIP system coding for modern DOiP‑enabled Jaguar and Land‑Rover vehicles.
Many DOiP‑architecture JLR chassis support ACC Stop‑Go Queue‑Assist ADAS capability; however, base‑trim vehicles come fitted with standard cruise‑control and omit the long‑range front radar sensor and associated steering‑wheel switch hardware. Simply installing the OEM radar sensor and steering‑wheel controls alone will not activate full Stop‑Go functionality. Therefore, without validated CCF configuration, the ADAS domain‑controller, DADC digital‑instrument‑controller, IMC infotainment‑master‑controller and GWM gateway ignore radar‑object‑detection inputs, trigger ADAS‑related DTC faults and hide ACC‑Stop‑Go configuration menus within instrument‑cluster and Pivi‑Pro interfaces.
In addition, we utilise certified Pathfinder DOIP programming to update ADAS, DADC, IMC and GWM gateway CCF parameters. Specifically, this enables long‑range radar‑object‑processing logic, Queue‑Assist stop‑and‑go deceleration‑acceleration profiles, following‑gap adjustment and instrument‑cluster ACC graphic displays. We supply genuine OEM front long‑range radar‑sensor assemblies, steering‑wheel switch modules, CAN‑FD bus harness adaptors and bumper‑mounting hardware for retrofit‑eligible vehicles.
Product Technical Overview
JLR OEM Adaptive Cruise Control with Stop‑Go (Queue Assist) is a radar‑based longitudinal ADAS cruise‑control system managed by the ADAS domain‑controller. Furthermore, the ADAS unit communicates over CAN‑FD bus with DADC, IMC, powertrain ECUs, ABS‑DBC brake modules and GWM gateway to process long‑range radar target‑data, manage acceleration and deceleration, and execute full‑vehicle stand‑still capability in heavy‑traffic scenarios.
The long‑range front radar continuously monitors vehicles ahead. As a result, the system maintains a driver‑selected following gap, automatically adjusts cruising speed, brings the vehicle smoothly to a complete halt in stationary traffic and resumes travel after traffic restarts with accelerator tap input. This reduces driver workload during highway and congested urban‑traffic conditions. The system works in conjunction with forward‑collision‑mitigation logic for added safety.
Physical fitment of radar sensor, steering‑wheel switches and wiring harness cannot deliver complete feature‑operation. Meanwhile, valid CCF build‑file flags must notify the vehicle network that ACC Stop‑Go radar hardware is physically installed. Multiple DOiP‑architecture JLR platforms require explicit CCF re‑configuration to unlock Queue‑Assist stop‑and‑go control‑tables, radar‑target‑filtering and DADC instrument‑cluster ACC‑status‑display logic.
Generic aftermarket wiring and unvalidated coding cannot replicate JLR factory radar‑calibration parameters, stop‑go acceleration‑ramp profiles and ADAS fault‑monitoring rules. Consequently, poor‑quality configuration can produce intermittent ADAS‑DADC DTC faults, unstable target‑tracking, missing Queue‑Assist stand‑still functionality or persistent ADAS‑system warning‑lamp illumination.
Our programming strictly follows official JLR OEM ADAS‑safety‑system technical specifications. Note that we apply only validated CCF configuration‑flag edits, paired with required radar‑sensor static alignment procedure. Permanent destructive ADAS‑controller ECU‑flash operations are avoided where possible. All factory collision‑mitigation safety‑routines, diagnostic‑logging routines and bus‑signal‑protection stay fully intact, preserving long‑term radar‑sensor and control‑module‑hardware reliability.
Core OEM Technical Features
After hardware fitment, radar alignment and DOIP configuration, Adaptive Cruise Control with Stop‑Go operates strictly to original JLR factory specifications.
Genuine OEM ACC Stop‑Go Queue‑Assist maintains configurable following‑distance gaps, automatically matches speed to preceding‑vehicles and performs smooth full‑stop manoeuvres in traffic queues. Moreover, vehicle resumes cruise operation by tapping the accelerator pedal once traffic moves forward. ACC status, set‑speed and gap‑level graphics render natively on the DADC instrument‑cluster display.
The system works alongside existing Autonomous Emergency Braking and forward‑collision warning functions. In addition, ADAS‑system status signals transmit correctly across CAN‑FD bus. No persistent safety‑system fault lamps appear after successful configuration. Existing standard cruise‑control, Pivi‑Pro infotainment and powertrain functions retain full operational capability alongside ACC Stop‑Go features.
Every radar‑target‑filter value, stop‑go acceleration‑deceleration ramp and following‑gap threshold retains OEM‑factory‑calibrated values for JLR Adaptive Cruise Control with Stop‑Go specification.
Key Technical & Functional Benefits

- Native Cluster & Pivi‑Pro ADAS Integration: Retain native instrument‑cluster ACC‑status‑graphics and Pivi‑Pro driver‑assistance configuration menus.
- Fault‑Free Multi‑Module Calibration: Dealer‑grade DOIP programming plus radar‑sensor static alignment and functional‑validation maintains clean CAN‑FD‑bus communication with zero residual ADAS‑related DTC fault‑codes.
- Warranty‑Safe Reversible Configuration: Validated CCF‑flag edits; revert back to standard‑cruise‑control baseline settings without irreversible module‑modifications.
Vehicle Compatibility
This Adaptive Cruise Control with Stop‑Go retrofit and coding service supports DOiP‑capable JLR platforms mechanically compatible with OEM long‑range ACC radar‑sensor hardware.
Supported platforms include New Range Rover L460, Range Rover Sport L461, Defender L663, Discovery 5 L462, Velar and latest‑generation premium Jaguar DOIP‑chassis models with Pivi‑Pro infotainment. Note that some chassis require full complete retrofit‑kit including front radar‑sensor unit, ACC steering‑wheel switches and CAN‑FD‑bus wiring‑harness adaptors. Alternatively, other vehicles have partial pre‑installed wiring provisions for ACC‑ADAS components.
Vehicles without compatible bumper‑mount geometry or non‑compliant ADAS‑controller firmware revision are not eligible for this upgrade. Before technicians commence mechanical‑installation or coding‑tasks, our team completes full pre‑program diagnostic‑scan. Specifically, this scan validates ADAS‑DADC‑IMC module firmware‑versions, CAN‑FD‑bus stability and genuine ACC‑Stop‑Go‑hardware eligibility‑status including existing ADAS‑system health‑checks.
Service & Transactional Details
Our complete service workflow opens with multi‑module pre‑upgrade diagnostics covering ADAS domain‑controller, DADC digital‑instrument‑controller, IMC infotainment‑master‑controller and GWM gateway unit.
We read existing ADAS‑system DTC history, verify existing driver‑assistance operational health and assess front‑bumper‑mounting and CAN‑FD‑bus‑wiring eligibility for Adaptive Cruise Control with Stop‑Go retrofit hardware. Furthermore, technicians perform full mechanical installation of genuine OEM long‑range radar‑sensor assembly, ACC steering‑wheel switches and CAN‑FD‑bus harness adaptors following Jaguar Land‑Rover official workshop‑service‑procedures for bumper removal and ADAS‑sensor fit‑ment.
After mechanical fit‑out, radar‑sensor static physical alignment and connector validation, technicians run official JLR Pathfinder DOIP CCF programming. This procedure enables ACC‑Stop‑Go‑Queue‑Assist‑system parameters and synchronises ADAS‑DADC‑IMC across the vehicle‑network data‑streams.
We then execute full functional‑validation‑testing including radar‑target‑detection response, following‑gap adjustment, Queue‑Assist full‑stop‑and‑resume behaviour and instrument‑cluster ACC‑status‑graphic verification. Lastly technicians clear all residual fault‑codes to deliver consistent long‑term OEM‑standard Adaptive Cruise Control with Stop‑Go performance.
