Disable 2018+ Land Rover AKL Active Alarm: Autel IM608, Yanhua ACDP or CG100X?

 All three tools — Autel IM608, Yanhua ACDP, and CGDI CG100X — can disable the active factory alarm on 2018+ Jaguar Land Rover (JLR) All-Keys-Lost (AKL) situations, but they work through very different methods (OBD/jumper bypass vs. module direct/EEPROM writing).

1. Autel IM508S / IM608 II

Method:

OBDII / Jumper-wire connection to the RFA (Remote Frequency Actuator) module using specific CAN wiring diagrams (or Autel’s JLR alarm bypass cable).

CAN Wiring (Typical): CAN-H (Pin 6) → Yellow/Orange; CAN-L (Pin 14) → Yellow/Purple.

Note: Wire colors may vary on some modules — CAN-H (Pin 6) may be Green; CAN-L (Pin 14) may be Brown.

Menu Path:

Manual selection -> [Model] -> [Year] -> Smart Key -> Select Control Unit -> RFA replacement -> Disable anti-theft alarm function

Pros:

• Direct software-driven routine via the diagnostic tablet interface.
• No need to desolder or read/write chips on the board if using the proper CAN jumper configuration.

Cons:

• Requires custom or dedicated jumper wire/bypass connections to the RFA and OBDII port.

2. Yanhua ACDP (Module 24)

Method: Direct CAN-bus connection to the RFA module using ACDP Module 24 License (with a free software update) paired with a PCAN, PTCU, or PECU cable.

Connection Steps:

• Locate the RFA module (do not disconnect the main RFA connector).
• Insert the white CAN_H wire into Pin 2 and the green CAN_L wire into Pin 20 of the RFA connector (verify model-specific diagram).

• Run ACDP app/software, navigate to JLR IMMO-> Program smart key (2018-)-> Replace RFA Program key-> OBD Programming RFA-> Turn off anti-theft alarm, and follow the on-screen prompts to operate.

Pros:

• Free update added to Module 24 for JLR AKL active alarm handling.
• Avoids destructive desoldering by interfacing directly via targeted CAN pins on the RFA harness.

Cons:

Requires Module 24 authorization and specific cables (PCAN/PTCU/PECU)

These cables are included in some ACDP modules, you have the related module, you can use them directly. Otherwise, you need to buy the cable separately.

• PCAN Cable: Included in Yanhua Module 3
• PECU Cable: Included in Yanhua Module 18
• PTCU Cable: Included in Yanhua Module 19 / Yanhua Module 36

3. CGDI CG100X Programmer

Method: Bench/EEPROM flashing of the Body Control Module (BCM) / integrated gateway-BCM chip.

Connection Steps:

• Locate and connect 8 wires to the BCM chip (e.g., 95128 / 95X series EEPROM) following the CG100X wiring diagram.

• Navigate to: 8-pin chip > 95X > 95128 in CG100X software
• Read and save the original chip data.

• Write the modified/alarm-off flash file (sourced via CG technical support or a verified third-party matching the specific model year) back to the chip.

Pros:

• Bypasses live network/OBD lockouts by directly modifying the BCM EEPROM data on the bench.

Cons:

• Requires physical bench hookup (8-wire soldering or clip connection) to the BCM board.
• You must source the exact right alarm-off flash file for your specific model/year variant.

Summary Recommendation

• Choose Autel IM608II/IM508S if you prefer an on-car diagnostic/software routine using custom CAN jumper wires into the RFA/OBD setup.
• Choose Yanhua Mini ACDP if you already have own an ACDP key programmer and want to use its Module 24 license and harness/PCAN bypass method.
• Choose CG100X if you prefer (or are forced into) a bench-programming approach reading/writing the BCM EEPROM chip directly.

Why Kohex LED Flashes Red: Understanding Kohex Status Indicators in Flex

 Learn what a flashing red LED on Magic Motorsport Korhex means and how to identify normal operation during ECU access, BOOT glitch procedures, and Flex ECU Programmer programming workflows.

A flashing red LED on Korhex adapter can look like a hardware problem, but that is not always the case.

Many users notice that the Flex software shows Korhex adapter as connected while the LED near the USB and power connector continues flashing red. This often leads to concerns about a defective tool, power issue, or connection failure.

However, a flashing red LED does not automatically indicate a hardware fault.

When Korhex Tool is connected but not actively working with an ECU protocol that requires its functionality, the red light may continue flashing even though the device is operating normally. In this state, the adapter is connected but idle.

Understanding Korhex LED Status

Different LED colors indicate different operating stages:

• Flashing Red: Korhex is connected but not actively engaged in a supported ECU operation.
• Green: The connection process has been successfully established.
• Blue: Korhex is actively performing the glitching operation required for ECU access.

The blue status is particularly important during supported BOOT glitch procedures, where Kohex uses electromagnetic fault injection to gain access to protected ECUs.

Before Assuming There Is a Problem

If the software detects Korhex Boot Glitch Tool but the LED continues flashing red:

1.Verify that the selected ECU protocol supports Korhex.

2.Confirm that the target ECU requires Korhex functionality.

3.Follow the recommended connection procedure for that ECU.

A red flashing light while sitting at the connection screen does not necessarily mean the adapter has failed.

Using Connection Logs for Troubleshooting

If the connection process fails, additional information can be collected from the connection history logs stored in the Flex installation directory under the dev profile history folder.

Providing these logs to technical support, along with the ECU information, can help identify the cause of the issue more effectively than relying on LED status alone.

Key Takeaway

A flashing red Korhex LED by itself is not proof of a hardware fault.

• Red indicates the adapter is connected but idle.
• Green indicates a successful connection stage.
• Blue indicates an active glitching process.

Before replacing hardware or reporting a fault, verify the selected protocol, confirm ECU compatibility, and review the connection logs if the access procedure fails.

How to Activate and Use Korhex Boot Glitch Tool with Flex?

 Korhex Boot Glitch and MCU Access Tool is an EMFI add-on for Magic Motorsport Flex ECU Programmer. It is made for locked ECUs that normally need soldering or board work: with the right mask, the antenna tip is placed on the processor, and Flex can gain access without removing components.

What is included in the Korhex Pack?

The kit comes in a blow-molded case.

Inside, you can get Korhex main unit, adapters and cables.

A set of adapters called masks.

Each mask sits on top of the processor and shows the exact contact point for the antenna tip.

If your processor is not included, you can 3D print a matching mask.

The main connector is marked Unit G, and the antenna is at the end of the unit.

How to Activate Korhex?

Korhex must be activated before use.

After activation, the Korhex icon appears on the left in Flex, and an image tutorial is available in the top right corner.

Activation steps:

• Open Flex software
• Click Helpdesk to enter the user portal

• Select Add Tool, and choose 001 MMS Korhex tool

• Input the serial number on the back of the Korhex unit to bind it to your account.

How to Use?

1.Plug Korhex Boot Glitch Tool into the Flex setup, launch the software, pick the correct ECU model, and press Connect.

2.Power-up starts with a red flashing LED while the tool detects the ECU and opens communication.

3.When the ECU ID comes back, line up the antenna over the processor with the mask as the placement guide; the glitch phase normally lasts around 10 seconds.

4.While glitching is active, the primary LED changes to blue and both small end lights turn on — this is the only moment EM pulses are being delivered.

5.Access is confirmed when the LED becomes green and the tool shuts down its output; at that point Korhex Tool has done its job and may be unplugged.

After Access Is Gained

With the processor unlocked and the passwords released, type them into Flex, save a complete backup first, then perform any required ECU reads or writes.

Keep in mind that Korhex MCU Access tool only opens the door — the actual reading and writing always take place inside MMS Flex software.
