How to Connect OBDSTAR CAN Direct V2 Cable for Renault?

How to use/connect the OBDSTAR CAN Direct V2 cable on Renault cars?

The aim is to access to the c can after gateway, skipping it.

Is there any scheme or picture available on the G3 during the prompt?

Here is the clue.

OBDSTAR G3 will show the scheme and pictures. You can view it in the immo menu without connection to the vehicle.

The piercing clamps should be connected on two wires of the BCM.

Then connect OBD cable with vehicle and device. One end need to be connected to OBD2 port.

 

The CAN Direct V2 cable is used on following Renault models for spare key programming, not All keys lost.

2020- RENAULT Clio 5

2020- RENAULT Captur

2020- RENAULT Arkana

2020- RENAULT Kangoo

2020 RENAULT Espace

2021- RENAULT Scenic

2020- RENAULT Zoe

2022- RENAULT Traffic

2021- RENAULT MEGANE 4 PH2

 

Take an example:

Add a 2022 Renault Clio 5 blade key using the OBDSTAR X300 Classic G3.

During the procedure, data was retrieved from the CAN bus using the CAN DIRECT V2 adapter; the Flash memory was read, the PIN code was obtained, a precoded key was generated, and the keys were programmed.

 

Tools used:

OBDSTAR X300 Classic G3

OBDSTAR CAN Direct V2 cable or 16+32 cable

Good charger

Working key

A new key to be programmed

 

Procedure:

NOTE: It is important to use battery support unit or at least good charger.

 

Step 1: Read Dflash

Select Renault- Clio 5- 2020 to 2024- Blade
Read Dflash- via OBD.

This function requires a harness connection to the gateway
There are two connections available.

Use C1022 CAN Direct V2 or C1007 Renault 16+32 harness cable.

Here we use the CAN Direct V2 adapter to connect the gateway.
G3 will show you connection diagrams.

Connect CAN Direct kit with BCM.

Read and save D-flash data.

Step 2: Read PIN Code
Load D-flash data to retrieve PIN code.

Step 3: Make dealer key
Choose Load D-flash or manually enter the 28-digit PIN code to make dealer key.
Make dealer key successfully.

Step 4: Program keys

Select Program keys.

Turn the ignition ON with a working key.
Load Dflash to program keys.

Enter the number of keys to be programmed.

All keys will be deleted.
Insert the keys to be programmed and turn the ignition on.
Learn 1st ok
Insert next key to be programmed and turn the ignition on.
Learn 2nd key ok.

Test both keys.

Model example: 2019 Peugeot 4008 ID4A smart key (all keys lost)

 

Procedure:

Connect G3 with vehicle via OBD socket.
In G3, go to IMMO- Peugeot/Citroen.
Select the appropriate software version.
Select Read PIN Code function– By Key SIM (ID4A).

Turn on the emergency indicators and press the Start button once.
Connect Key SIM simulator to G3.
Initializing key SIM simulator.

Complete follow operation within 150s:
Place the simulated key correctly in the vehicle’s key sensing area (emergency start position).
Try turning the ignition on 5-10 times.
Press the Start button until the dash displays “No key detected”. Then release the button until the message disappears.

OBDSTAR G3 calculates 4-digit pin code successfully.

Now you can proceed with key programming operation.

OBDSTAR ECU Master Read and Write Chrysler GPEC3 ECU

In this article, we walk through the process of reading and unlocking a Chrysler Continental GPEC3 ECU using the OBDSTAR ECU Master programmer.

This guide covers boot mode reading, EEPROM and internal flash backup, ECU unlock, VIN writing, and checksum handling.

 

Previous Tool Attempts

Notably:

DC706 previous Chrysler old sw failed to read it in boot mode

Multiprog also failed to read it in boot mode

The ECU Master is being tried to see if it will work after the update.

 

Selecting the ECU in the Tool

The selection process:

• Select by brand — Continental
• Go to type
• Select GPEC3

There is also a new OBD option available from the recent update, but boot mode is being used for this demonstration.

Boot Mode Setup

For boot mode, the ECU must be opened. The connection requires:

A 120 ohm resistor between CAN L and CAN L.

Once the connections are made:

Select Start.

Select Boot to perform the reading.

Boot Loader and Connection

The tool waits for the boot loader to be written onto the ECU so it can connect. The boot loader begins loading — a good sign that connection will succeed.

The ECU Master connects successfully.

 

Reading the ECU

With the connection established, all functions are tested:

• Special functions
• Read EEPROM
• Read internal flash

 

EEPROM Reading

The internal EEPROM is read. This ECU uses an external EEPROM, so it can be opened and cloned by reading the external EEPROM.

Important note: The most important thing is to make sure the map — what is called the internal flash — looks the same, or the vehicle will throw codes that might not otherwise appear. This happens often.

The EEPROM is saved.

Internal Flash Reading

The internal flash is also read. The update appears to have helped. The tool reads all the sectors — approximately 20 sector addresses for the internal flash.

With this capability, one-on-one cloning is possible if the flash is not damaged and the client brings the ECU in. Both the external EEPROM and the internal flash can be read, meaning there may be no need to go online to update it or use another ECU to update the flash itself.

Tuning and VIN Considerations

For this ECU:

If you want to tune it, you must unlock it first before tuning.

If you want to change the VIN, that can be done in special functions — which the update reportedly added.

 

Saving the Flash

The flash is saved so that if the client wants it, the file is available. The tool prompts to save.

 

ECU Unlock

The ECU unlock function is selected. With ECU unlock:

It reads the internal flash

Read and save flash.

It will then write it back onto the ECU.

The unlock completes successfully.

VIN Writing

The VIN function is selected. The tool asks to select the EEPROM because the VIN is normally stored in the EEPROM.

For the GPEC3, there are three locations for the VIN. When changing any number:

The change is made (e.g., changing the last digit to 8)

The tool writes it automatically

To verify:

Read the EEPROM

Save it

Compare it with the edited version

The write can also be done for verification purposes. The original VIN is written back so it can be read in the ECU.

Important: With the VIN, you must select the EEPROM you want to change the VIN in. When the change is done, it writes it back. The tool reads to allocate the VIN numbers.

Note: The ECU Master requires an internet connection — without it, you cannot connect.
Writing the Flash Back

The flash is written back because of the unlocking performed earlier.

Checksum (CS) Correction

When you see CS in the ECU Master, it means checksum. The tool performs a checksum for you.

It cannot be given a 100% guarantee, but it works mostly on Bosch ECUs and some Continental ECUs

All the AC Delco ECUs it supports also get checksums

This is a Continental ECU, and the checksum is being performed on it.

The checksum takes a long time because it must be uploaded to the server. The server does a lot of work — it checks the file, goes through it, and brings it back for writing. This verifies the file is okay.

Note: Sometimes the checksum can be skipped if you don’t want a long wait, don’t have time, or have made edits that might not pass. However, the checksum is very important because it helps prevent breaking the ECU.

 

Writing Process

During writing:

Certain sectors are skipped

Only the needed sectors are written

This makes writing faster because skipping sectors avoids delays

The tool erases and writes sector 20 out of 20 addresses.

 

Sector 20 is written successfully. The tool is disconnected.

Summary

This case demonstrates reading and unlocking a Continental GPEC3 ECU with the OBDSTAR ECU Master. Key takeaways:

• The ECU Master’s new software matches DC706 functionality, with a recent OBD mode update
• Boot mode requires a 120 ohm resistor on the CAN line
• The tool connected successfully where Multiprog failed
• External EEPROM and internal flash can both be read for one-on-one cloning
• ECU unlock is required before tuning
• VIN writing requires selecting the EEPROM (three VIN locations on GPEC3)
• Checksum (CS) is handled via the server — important for preventing ECU damage
• An internet connection is required
