OBDSTAR DC706 Read BYD Delphi MT22.1 ECU on Bench

 OBDSTAR DC706 read and write BYD Delphi MT22.1 Denso ECU on bench successfully.

I’ll walk through my experience reading and cloning a Denso MT 22.1 ECU using the Obdstar DC706 tool. This process involves bench reading, VIN writing, and troubleshooting common issues—helpful for locksmiths, mechanics, and automotive enthusiasts.

Step-by-Step Process

1. Connecting to the ECU

  • The Denso MT 22.1 ECU was initially attempted with Xhorse Multi prog, but it required boot mode, which was unnecessary with the Obdstar DC706.

  • Using a K-line connection, the Obdstar successfully established communication with the ECU.


2. Reading the ECU Data

  • The reading process was slow due to the K-line protocol but stable.

  • The tool first writes a bootloader before extracting the flash data, ensuring compatibility.

  • A key advantage of the Obdstar DC706 is its ability to read and write VINs, useful for virgin ECUs or replacements.


3. Handling a Virgin (New) ECU

  • The new ECU had no pre-written VIN, so the plan was:

    1. Read and save the flash data for future use.

    2. Write the correct VIN if the original ECU couldn’t be read.

  • Avoiding physical opening (desoldering) was preferred to preserve the ECU’s integrity.


4. Troubleshooting and Next Steps

  • If the original ECU couldn’t be read via bench mode, boot mode (desoldering) would be the fallback.

  • The saved flash data from the new ECU could be reused for future cloning jobs.

Key Observations

Obdstar DC706 Benefits:

  • Works without opening the ECU (bench mode).

  • Allows VIN writing, essential for new or replacement ECUs.

  • More user-friendly than Multiprog for this application.

Challenges:

  • Slow reading speed due to K-line communication.

  • Boot mode may still be needed for problematic ECUs.


OBDSTAR G3 Adds 2020 Renault Captur II Smart Key via OBD

 Adding a new smart key card to a Renault Kaptur 2020 using the OBDSTAR X300 Classic G3 tool is a detailed process that requires careful execution. Below is a step-by-step guide based on a real-world procedure, including important tips during the process.

Tools required:

OBDSTAR X300 Classic G3
Xhorse blank XS series smart key
16+32 Gateway bypass adapter

Original smart key

 

Step 1: Accessing the Gateway Module

The gateway module (gate) must be accessed to bypass the vehicle’s security system. According to the manual, it is located under the dashboard, but in this case, it was found behind the multimedia unit.

OBDSTAR G3 Adds 2020 Renault Captur II Smart Key 1

Steps to Access the Gateway:

  1. Remove the glove compartment and surrounding plastic panels.

  2. Detach decorative trims, which may be secured by bolts hidden beneath them.

  3. Loosen (or remove) the multimedia unit to reach the gateway, located at the top behind it.

Step 2: Connecting the OBDSTAR G3 Tool

Once the gateway is accessible:

  1. Use a 16+32 adapter to connect the gateway’s 32-pin connector.

  2. Ensure the CAN lines are fully accessible for direct communication.

  3. Connect an external power source to prevent voltage drops during programming. External power is critical to avoid interruptions.

Read immo status.

Check the immobilizer memory to confirm key registration.

Both new and original keys should start the vehicle.

 

Common Issues and Solutions

  • Failed Key Programming:

    • If the original key fails to program, try adding a new key first, then reprogram the original.

    • Ensure the transponder is correctly placed in the reader.

  • Incorrect Key Count Display:

    • The immobilizer may show incorrect key counts. Verify functionality by testing each key.

  • Alternative Method (HFM Direct Access):

    • If the gateway is hard to reach, the HFM module (located near the dashboard) can sometimes be used to extract the PIN directly.  Direct reading pin from HFM dump is better, in case of complete loss and failure without isk data you won’t be able to prepare the card. The task will be with two unknowns, no card and empty hfm. The dealer does not send cards prepared for the car. You can take isk data from the server, but the procedure will require a prepared card.
