OBDSTAR ECU Master: Renault ME17.9.23 Clone Guide

The Renault Kwid ECU ME17.9.23 TC1724 was brought in for cloning. The part number on the ECU is 0 261 S17 723. The goal was to read the ECU data using the OBDSTAR ECU Master, back it up, and then write the data back to verify the process works.

Bench Mode Connections

All necessary connections were made for bench mode operation. The wiring includes:

Positive and negative power connections

CAN High and Low wires for ignition

GPT wire (on the other side)

These connections are shown clearly so viewers can follow along.

Setting Up the OBDSTAR ECU Master

Once in the laptop interface, the ECU Master tool is opened.

The vehicle selection is:

Navigate to 17.9.23.

Select Renault — the ECU profile loads.

Select Bench mode.

The pinout diagram appears.

The ECU is identified — this is the ME17.9.23 TC1724 with part number 179 23.

Starting Bench Mode Communication

After confirming the pinout, the tool is started in Bench Mode. The device begins connecting to the server. A key point to note: the internet connection must be fast for proper communication. The tool needs a stable, high-speed connection to communicate perfectly with the ECU.

The reading and communication process begins.

Backing Up the ECU Data

Before any writing is done, the first priority is to back up the ECU data.

Read and save EEPROM data.

Read and save Flash data.

Writing the Data Back

After saving, the next step is to write the data back to the ECU to verify the process.

• Selecting the File
• The saved file is selected
• The file is opened
• The tool asks: "Do you want to check and verify?"
• Yes is selected
• The tool asks for the original file
• The original file is loaded

Writing Process

The writing process takes a little longer, which is why it is being done now. OBDSTAR ECU Master:

• Initiates the write
• Boot loader is loaded — writing the boot loader
• The file name appears — showing where the file was taken from
• The same file is being written back
• The ECU with part number 179 23 is being written successfully.

Completion

The work is now complete:

• The ECU has been read
• The data has been backed up
• The data has been written back
• The ECU is installed

The data will be returned to the same ECU and given back to the customer

Important Note on Adapters and Cables

Some users report that communication sometimes fails. To avoid this:

• Always use the original adapter
• Always use the original data cable (the serial cable)

This prevents device damage and avoids any issues with the tool.

How to Check a PSA MD1CS003 ECU is Locked or Not?

Question: It’s a Peugeot Partner 1.5 132hp with Bosch MD1CS003 ECU.

Car build date is 2020/06. Try to read this ECU with Flex programmer.
How do i know if ecu needs to be boot glitched or not?
Is there any danger of trying to connect and reading on non locked protocol if ecu requires boot glitch?

Here is the clue.

How to determine whether the MD1CS003 ECU is locked or not?

Way 1:

Just try normal bench read and you will know if its blocked. If locked then flex tell you.

Way 2:

Check the ECU label.
If 0281 034, 035 or 036 it’s not locked.
Also, 0281 037 101 not locked.
If more than "037" is locked.

FYI:

How to determine the TPROT lock status of PSA MD1CS003:
It can be quickly determined based on the part number.
Part numbers starting with 3XX indicate not locked;
those starting with 4XX or 5XX indicate a locked state, requiring an unlocking operation before normal data reading and writing can be performed.
