MMS Flex Read Mitsubishi Fuso EDC17CP52 ECU on Bench
Problem:
Tried to read a Mitsubishi Fuso Canter 3.0DDI 173 ps EDC17CP52 ECU with MMS Flex on bench mode but cannot read. What’s the problem?
Solution:
Same problem can also happen to other tools. You cannot even read this with Dimsport New Trasdata. You must open ECU and do it boot only.
2 solutions:
1). Open ECU and read in boot mode.
2). If you need to do it on bench mode, add a capacitor (10uf-50uf) on each GPT.
Must add capacitor to gpt pin this pinout also works for Edc17cp15.

How to Add 2021- Nissan Serena Smart Key with Autel?
Possible to program newer 2023 Nissan Serena smart key with Autel IM508/IM608?
Any risk if we try it with Nissan 40pin BCM cable?
Here is the clue.
Sometimes it works; sometimes it does not. If Autel fails, try Lonsdor. If all fail, try the key cloning function.
User’s working experience:
“Did one with Autel IM608 last week. After I plugged 40 pin cable, I lost communication. So I read basic data (key positions and ID’s) throught basic OBD connection and made key clone with Autel (but wrote lost ID in new key). Both keys worked perfect; no remote sync issue will appear cause there are 2 different keys ID’s.
Autel NXP copy is the the same as NXP killer.
NXP killer makes only direct clone of key, you cannot change ID. Its simple copy-paste function. Autel hacked this type of NXP chip too with changing ID’s feature. So with NXP killer you could have sync issues, with autel you won’t (if you choose lost keys ID to new one).
Autel MaxiIM IM508/IM608 series now supports Nissan NCF29Ax NXP smart key cloning function.
Supported models:
2019- Ariya, Pathfinder, X-Trail, Qashqai, Sylphy, E-POWER, HB18, KICKS, MICRA, Note e-POWER, NP300 FRONTIER, NAVARA, NP300 NAVARA, PRIMASTAR, R53, ROGUE, Serena e-POWER, Sylphy e-POWER, SYLPHY Zero Emission, TOWNSTAR.
2121- RH850 series Infiniti QX60, QX60 hybrid
Supports copying AUTEL ikey universal and original keys. AUYEL smart keys need to be generated in advance.
Remove the original car key.
Connect the XP400 Pro programmer, key board, and APB131 adapter.
If you cannot find the wiring diagram for the exact key board type, refer to the key chip wiring diagram based on the chip type to perform the reading.
Read and save key data.
Then write a new Ikey or original key.

Xtool Read 2022 Geely Coolray ESK Code and Add Key
Today we’re working on a 2022 Geely Coolray. The customer is trading in the car, and as often happens, without a second key, they accept the car at a lower price. The task is to make a second key.
Programming keys for these cars requires a 32-digit ESK code, which isn’t always readable, and the reading procedure carries certain risks.
Few people do it correctly, and at best, you’ll end up with non-erasable errors, and at worst, you’ll lose your property.
We used Xtool X100 PAD3 (or more advanced tablets) with KC501 to program key.
Read 32-digit ESK code, then add a smart key.
Preparation time: 30 minutes.
Below are some photos of the process.
Unlock Citroen Berlingo MD1CS003 with Flex in Boot
Today we’re talking about a very controversial ECU — the MD1CS003.
Many people report problems with it, but in most cases the issue is not the protocol itself. The Flex boot glitch works very stable and reliably when everything is prepared correctly.
The key point is the BOOT connection — it has to be absolutely solid. Any interruption during the process can lead to the kind of IMMO-related problems people are reporting.
So before blaming the protocol, check the connection first.
MD1CS003 does not forgive bad BOOT connections.
I've done 10 ECUs never had problems , correct connection and all be okay.

The Launch Smartlink C V4 VCI comes with upgrades to both its software and hardware.
1. Hardware Performance Upgrade
Connector Performance Leap: The connector’s CPU has been upgraded from a single-core to a dual-core processor, with the clock speed increased to 1.7 GHz. The RAM has been expanded from 256 MB to 1 GB, significantly accelerating computational response speed and enabling more efficient command execution. The CAN bus has been upgraded to 4 channels of CAN FD, delivering comprehensive improvements in communication bandwidth and transmission capacity to support diagnostic requirements for a wider range of newer vehicle models.
2. Diagnostic Functionality Upgrade
Graphical Diagnostic Display: Supports graphical visualization of special functions, topology maps, and data streams. Data trends are intuitively visible, enabling more precise and efficient fault localization and eliminating the need for cumbersome text-only interpretation.
High-Speed Scanning: Utilizes multi-channel synchronous scanning technology to process diagnostic tasks in parallel. Compared to traditional single-channel scanning, this significantly improves efficiency, delivering faster diagnostic speed and reducing repair time.
AI-Powered Fault Remediation: Visually displays fault points and provides targeted, highly feasible optimization solutions.
How to Solve Yanhua ACDP2 BMW BDC 085 Lost Coding Problem?
Problem:
Tried to add a spare BMW BDC 085 version key with Yanhua ACDP2 but failed. It says “usb line is poll out” and coding was lost.
14V stable power supply.
Not touched anything during preprocessing.
Any solution?
Solution:
You can restore it with ACDP itself.
If does not work error “Restoring Coding data failed, please use BMW ESYS to restore the Coding data”, follow the suggestion and restore data with E-sys.
User report:
1). Restored (remotely) with esys and added key on bench.
2).
I had the same issue with a BDC in two different occasions.
I ended up restoring data with Vvdi bim tool.
