How to Use OBDSTAR Li Auto C1032 Adapter?

 How to connect the OBDSTAR Li Auto C1032 harness adapter with BCM module and perform key programming with X300 Classic G3?

Remove the driver's side trim panel.



Unclip the retaining clips. Remove the cover panel.


Locate the BCM module.
Unplug the blue connector.


Insert one blue end of the C1032 cable into the vehicle's original blue socket, and plug the other blue end into the original port on the BCM.



The C1032 harness also has two black  OBD connectors — plug the male connector into the vehicle's OBD diagnostic port, and connect the female connector to the device's OBD cable.



Once connected, you can start programming the key.

OBDSTAR G3 MQB48 Cluster MP001 Connection Failed Solution

Problem:

Tried to read VW MQB48 cluster data for all keys lost using OBDSTAR X300 Classic G3 and C4-06 adapter. After setting up the connection as in the diagram, it says MP001 connection failed. Any solution?

Solution:

Reset MP001.

 

Solved. Reset device.

 

NOTE: 

Some users said you must connect the 12V charger directly to the MP001, not the OBD2 cable. This is not correct.

OBDSTAR engineer confirmed you can connect a 12V charger to either MP001 or OBD2 cable. Both work fine.

Toyota Camry 2022 Denso ECU IMMO OFF by OBSDTAR G3

How-to: step-by-step bench IMMO OFF for Toyota Gen3 Denso ECU using OBDSTAR X300 Classic G3 with ECU license.

 

Model Example: Toyota Camry 2022

 

Procedure:

1. Determine the ECU Generation & Chip

The process changes depending on your Camry’s model year:

Older Camrys (Denso/Delphi): Handled via standard EEPROM reading.

Modern Camrys (Gen 3 / Gen 4 systems) usually feature Toyota Gen 3 ECUs with R7F701216 processors or Denso Gen 4 processors.

 

2. Read and Backup original ECU Data

Connect your OBDSTAR G3 to the internet and ensure it is updated to the latest software version.

Power on the tablet and select ECU Advanced (or ECU Flasher / Clone depending on your license activation).

Select ECM – TOYOTA – Toyota Denso Gen3 ECM R7F701202- Bench Mode with MP001.

Click on Pinout / Wiring Diagram. Follow the precise on-screen schematic to hook up the 12V, GND, CAN-H, CAN-L, and ignition wires from MP001 adapter to the ECU pins.

Click Connect on the G3 screen to establish communication.

Click Read INT Flash (and Read INT EEPROM / DFlash if available).

Crucial: Save these original backup files safely to your tablet.

3. Apply the IMMO OFF Modification

Once backup files are securely stored, locate the IMMO OFF function menu under the Special Function options for your specified controller.

Select IMMO OFF.

The G3 will prompt you to select the original file you just read from the ECU.

The software will process the file, perform a checksum correction automatically, and generate a modified “Immo Off” bin file.

4. Write Data Back to the ECU

Select Write INT Flash (or Write EEPROM depending on the specific model’s IMMO architecture).

Select the modified “Immo Off” file generated in the previous step.

Keep power fully stable while the G3 writes data and verifies the blocks.

Once the application prompts Operation Success, select Disconnect, power down the MP001 adapter, and safely reinstall the ECU back into the Camry.

If your goal is instead just to bypass an All Keys Lost situation rather than deleting the immobilizer completely, you can read the Smart Key Box data via OBD instead.

How to Add 2021 Renault Clio V Blade Key with OBDSTAR G3?

In today’s guide, we’ll walk through the process of programming a spare key for a 2021 Renault Clio 5 using the OBDSTAR X300 Classic G3. This particular vehicle requires special attention due to its gateway system, making the procedure slightly more complex than standard key programming.

 

Required Equipment and Preparations

• Before beginning, ensure you have the following equipment ready:
• OBDSTAR X300 Classic G3 with the latest software updates (version 42.0 or newer at the time of this guide)
• Three-button retractable key (blade type, compatible with Renault)
• Nissan/Renault 16+32 cable – essential for bypassing the vehicle’s gateway
• Battery maintainer/charger – critical to prevent voltage drops during programming
• Stable internet connection – required for the IMMO application

 

Understanding the Renault Clio 5 Gateway System

The Renault Clio 5 is equipped with a gateway module that blocks direct OBD connections. This means you cannot simply plug into the standard OBD port under the dashboard. Instead, you’ll need to access the gateway module directly.

Access Method

• Remove the glove compartment
• Locate the small gateway box behind it
• Connect using the Nissan Renault cable (16+32 pin configuration)

This is the recommended method (Method 2) as opposed to connecting through the engine compartment CAN Direct V2 cable (Method 1).

 

Step-by-Step Programming Procedure

1. Initial Setup

• Connect your battery maintainer to ensure stable voltage throughout the process

• Connect the 16+32 cable to the gateway module behind the glove box

• Ensure your OBDSTAR G3 has a stable internet connection

• Open the IMMO application on your device

2. Vehicle Selection

• Navigate to the Renault section in the IMMO app

• Select the vehicle model: Clio 5 (2020-2024)

• Choose the key type: standard blade key (not hands-free/card type)

3. Reading the Flash Data

• Select “Read Flash via OBD” option

• The system will detect the gateway and offer two connection methods

• Choose Method 2 (FCA cable behind glove box)

• Turn the ignition ON using the customer’s existing working key

• Important: Take a photo of the data displayed on screen – this will be helpful if you need to rewrite data in case of internet disconnection

4. Data Processing

• Wait approximately 12 minutes for the data to be read and processed

• A progress bar will show the loading status

• Once complete, follow the on-screen prompt to open and close the driver’s door
  

  

5. Save the File

• Save the file with a recognizable name (recommended: include the chassis number, vehicle model, and customer name)

• This file contains critical data for the key programming process

6. Generating the New Key

• Navigate to the “Make Dealer Key” function

• Load the saved flash file

• The system will display the PIN code – this is extremely important.

• Take a photo of the PIN code and consider providing it to the customer

• The PIN code allows for key replacement even if all keys are lost in the future

7. Key Programming

• Place the new blade key in the tablet’s detection zone (left side)

• Ensure the key is properly positioned

• Select “Key Programming”

• The system will verify all keys to be programmed (in this case, 2 keys total)

• Follow the sequential prompts:

  1. Turn ignition OFF

  2. Turn ignition ON with the customer’s original key – key programmed successfully

  3. Turn ignition ON with the new key – key programmed successfully

Completion and Testing

Once programming is complete:

• The central locking should function correctly

• All windows should operate as expected

• Verify the engine starts with both keys

Important Reminders

1. Always use a battery maintainer – voltage fluctuations during programming can cause failures

2. Document the PIN code – this is crucial for future key replacements

3. Keep the software updated – outdated versions may not support newer vehicle models

4. Take photos of all displayed data – useful for recovery if issues arise

5. Label saved files clearly – include vehicle details for easy identification
