How to Duplicate 2018+ JLR Keys with YANHUA MINI ACDP Module 47?

The YANHUA MINI ACDP with the new Module 47 can duplicate 2018+ JLR keys without removing the RFA. The procedure uses an ID-changeable aftermarket/universal key and the BAV-KEY adapter.


Connect and Identify the Vehicle

1. Connect the MINI ACDP to the vehicle OBDII port and use the standard ACDP power adapter (12V, ≥2.5A). Turn on the ignition so the instrument cluster lights up.

2. Open the ACDP APP and confirm the programmer is bound. Go to JLR >> ICP+OBD Duplicate key without removing RFA(2018-) >> OBD Identify Car Info.

3. Verify the original vehicle information, save a screenshot, and click Continue. Confirm that UWB, PE, and PS are turned off and that the key supports copying.

How to Disassemble VW MQB 5D Odometer?

This is a tutorial on disassembling the VW MQB 5D odometer. After that, we can install the Yanhua R7F701401/21-5D Interface Board to read and write data without soldering. By working with ACDP2 + Module 34, we can make data reading and writing safer for VW Golf 8, Teramont, Viloran, Tavendor, Lamando, Tiguan L, etc.


How to disassemble VW MQB 5D ODO?

Since the MQB5D odometer display and the housing are sealed with glue, you must be careful when disassembling them.


Based on these 3 buckle positions, determine the instrument's positive direction. To disassemble the instrument, it's recommended to use a sharp art knife.

1) Start from the lower left corner of the display.

2) Cut the sealant under and on both sides of the instrument.

3) Cut the sealant above the instrument.


Please Note: The below and on both sides.

 The blade should not be inserted more than 8mm deep to avoid scratching the inside of the odometer.

 When cutting the sealant, be careful not to tilt the blade upward.

 Do not pry the blade up and down.

 Be careful and slow when cutting.

disassemble-vw-mqb-5d-odometer-tutorial-3

When you're working on the top of the odometer, be careful of the wiring in the middle. So the blade should not be inserted more than 4mm deep at this position to avoid cutting the display cable.


After the sealant is cut, flip the display open. Place your fingers on the left and right grooves below. Remove the backlight panel and heat sink.


After completing, we can install the 5D Interface Board according to:

Yanhua Mini ACDP ICP Attempt To Start Mode BMW CAS3++ AKL

This is a tutorial on how to program BMW CAS3++ all keys lost in ICP attempt to start mode with Yanhua ACDP-2 BMW. The procedure mainly works on Module 1.


Power on the Mini ACDP 2 device.

Confirm the ACDP device has been bound.


Mini ACDP>> BMW >> CAS1~4 >> CAS3/CAS3+ >> ICP Mode >> MC9S12XDP512 >> IMMO

Click Help to complete the connection between ACDP and CAS ECU.


Step1. Read the CAS data

Please use the ACDP standard power adapter(voltage+ 12V, current > = 2.5A)

Please follow the wiring diagram to connect the ACDP. BDM adapter and CAS ECU.

Confirm vehicle info, click OK.

The backup file succeeded.

Step2. Generate Dealer Keys

All-key-lost(try 16 times or 64 times) >> OK

Connect the ACDP and BAV adapter according to the diagram and insert a blank key.

Verify key info.

Selected the " Original " data, and paid attention to the date and time of backing up files.

Verify vehicle info.

Select a blank key position >> Confirm if the current key is a Keyless go


Is the current key a Keyless Go?

Warning:

1. Only 2 Keyless Go are allowed for one car.

2. Please disable or delete the lost Keyless Go before adding a new Keyless Go.

3. Ensure there is one Keyless Go at most in the CAS before generating the key.

4. The Keyless Go will not be unlocked once generated.

5. After the keyless go is successfully generated, the method of gate learning cannot be used, and the generated data needs to be written back to the CAS for the keyless to take effect.


Remote key >> OK

The current CAS version type is the CAS3+ISTAP4* version. Generating the key requires up to 64 attempts. Please enter the number of current attempts.

Click on settings >> Enter 1 >> OK

Generate dealer key completed.


Load CAS onto the vehicle and verify the key function, there are 2 ways of operation at this time:

1. If the newly generated key can open the switch, click OK and follow the steps.

2. If the key cannot open the switch, remove CAS. Learn the key by reverse-writing ALL data to ensure that the key can open the switch.

Here's clicking "Cancel".

The backup file succeeded.


Return to the previous step.

Remove the CAS from the car.

Please try to start the car with the newly generated key.


Please install the CAS module on the car and start it with the current key. Click Yes if you can start the car. Click No if you can not start the car. If the car can not start, remove the key from the ignition switch and put it into the programmer before you click No.

Can the current key start the car? No

The number of current attempts is 03; click OK.

Generate dealer key completed.

Please try to start the car with the newly generated key.


If the newly generated key cannot start the car, put it back into the BAV adapter and click No.

Continue the fourth attempt until the new key can start the vehicle.

The new key can start the vehicle normally.

The program key succeeded.
