Here is a comparison table among Xtool’s DIY series diagnostic scanner D5, D5S, D6 and D6S.

Xtool D5 vs D5S vs D6 vs D6S

In sum:

The Xtool D5 and D6 series share the same hardware but differ in their software configurations.

Xtool D5 series is not full system diagnostic scanner, it supports 5 system diagnoses only. D6 series is for full system.

Special functions D5>D5S=D6>D6S. D6S has more special functions (30).

Both D5 and D6 support CAN FD protocol, but don’t support DoIP protocol.

Both scanners don’t support active test (di-directional control) function.

FYI:

Here is a real case shared by our customer, hoping to help those who are facing the same issue.

This is a BCM from a 2015 Ford Fusion. Try to clone the BCM module usingOBDSTAR DC706programmer.

The only option that looks close is the mpc5607 (Ford BCM Continental MPC5607) the picture looks the same minus that big green fuse or relay.

Remove the cover to determine exact chipset. If try this and the chipset is different will it damage the bcm or simply fail to connect.

I know the calibration number is different but if it’s the same vehicle with same vehicle.

Test report:

The 2015 Fusion BCM did work just an update calibration had 1 character different but everything worked.

There all the same it’s just the one in the picture on Obdstar that didn’t have the big green fuse this one had making us question if it was the same chip. But that’s a very good tip because it’s easy for people to remove fuses at the junkyard. Or this bcm being a little different have more or less fuses. So everything copied like normal.

He assumed that either cloning the module made both units have the same calibration or that both were so close to the same that everything worked. It worked.

By cloning it you are copying everything including calibration. As the term means. Cloning making a copy.

NOTE:

Always make sure you have the same fuses in the same places as the original bcm. If your BCM is slightly different from the pictures in OBDSTAR, send your BCM picture to OBDSTAR to verifiy first before operation.

FYI:

OBDSTAR G3 has an extra splitter to connect to this module and clamps for main positive and ground. The DC706 does not. So you can get aG3 with ECUlicense instead.

One of our customers reported that he failed to add a spare key to a BMW 316 G20 BDC3 system withAuel IM608 IIprogrammer.

He generated theAutel BMW ikeywith same fcc ID before programming, then disassembled the original key, read data and learn key. But the key is not working.

Possible solutions:

He made a mistake.

Don’t need to generate the key before programming!!!
The Autel is generating the new key automatically so you don’t have to pre-generate the new key.

The point is: Make another key without doing anything just put a new key on the programmer and everything will be handled successfully.

If you don’t have another Autel BMW ikey, no problem.
Generate the Autel key that you have as another key even if Hyundai or Kia and then put it directly on the programmer while programming the new key.
The point is to wipe out the BMW generation FCC ID from the Autel key that you have.

NOTE:

4. Make sure you follow the correct instructions/steps to add key. Double-check the wiring connection during the read key data process.

Here comes the user’s working experience on how repair BMW FEM/BDC module after programming failed withAUTEL IM508S.

"I worked on BMW X1 2017 BDC01. I pull FEM/BDC module out of car, connected it with godiag and started process as usual. After EEPROM successfully preprocessing, Autel started to program module to get SK but it wrote "Failed to program” and restored original EEPROM data back. After this, I put ECU back to car but it didnt start and ignition didnt wake up. So I tried to backup coding file but it didnt help. After little survey I tried to check software version (which I did also before I started programming) but Autel showed me "Software mismatch”. So I used ECU recovery process, choose original FEM/BDC data (backup done by reading ECU info) and it helped. So even I didnt program new key, I was able to repair ECU.”

For the future always read the EEPROM twice and compare it by seen first page and last page just simple tip if you keep using autel for BMW.

You can compare the two readings and see if they are exactly the same, Just to make sure that you get the same data.

Customers often report that theirOBDSTAR X300 Classic G3orDC706 fullversion software is missing certain applications. Below are some common issues and their solutions.

Case 1:

Activated the full software license to the DC706, but only the ECM software is available, while TCM and BCM are missing.

Solution:

Register device first, then go to Upgrade. Download and update BCM and TCM software.

Case 2:

Has activated the ECU, airbag and mileage license to the G3, but cannot see mileage function.

Solution:

Register device, go to Upgrade and download/update mileage software.

Case 3:

The OBDSTAR G3 has been activated with the ECU software package, but the TCM and BCM software are missing and cannot be found in the one-click upgrade list (No software can be upgraded. ).

Solution:

Problem:

Generated lost ID Range Rover Evoque 2018 usingXhorse XM38 JLR style smart key. Then programmed a key for a 2018 Evoque withvvdi key tool plus2 weeks ago.

Sometimes smart function works fine, sometimes no key detected, place the key to the sensing area, works. Sometimes no Buttons work, sometimes they work. Special issue when the key is in the shell. The original key works without problem. Any idea?

Possible solutions:

Solution 1:

Check the key fob battery (with new and good battery).

Solution 2:

Increase power output.

Go to menu where you generate the key.
Clickmodify and increase power setting.

Once you click on the modify button, it will read your key.
Then it will list button details, frequency, power etc.
Increase in increments of 5, so if it’s set to 5, change to 10 for example.

Solution 3:

Some people had the similar issue with XM38 smart key.

Use other keys. For example, useAutel iKey smart key.

Just upgrade him to the AUTEL key and do clone from BCM 1 key id or just buy an original key and add it by OBD.

Keydiy released a new programming socket for writing JLR KVM/RFA initialization data to the new JLR SPC chip. No soldering required. Here we will show how to write JLR RFA initialization data to SPC560 chip with Keydiy.

Tools required:

Keydiy KD-X4 key programmer

Keydiy JLR SPC560 chip programming socket

Blank JLR SPC560 chip

Mobile phone

OTG adapter

Procedure:

When we are working on the new Land rover Jaguar K8D2/JPLA/J9C3/M9R3 KeylessGo smart key system, we need to replace the RFA module/chip with a new module/chip. Usually, we need to solder wires on the KVM/RFA module.

With the Keydiy SPC programming socket, we no longer need to solder the wires.
You only need to place this chip into this programming socket.

Align the position of PIN1 in the chip to the 01 position in the socket.

After placing it properly, close the lid.

Then connect the socket with KD-X4 programmer.

Connect the KD-X4 with mobile phone via OTG adapter.

Then we proceed to write the initialization data with KD-X4. Keydiy app contains the initialization data.

RunKD-X4OBD App.

Go to IMMO Programming- KD-X4 App- Write file- Write JTAG (SPCXXXX) chip- RFA writes initialization data.
Select corresponding RFA immo versions.

Writing initialization data with the new SPC560 chip.

Then solder the chip to the RFA module.

Install the module back to the vheicle and proceed to other operations.
