CG FC200 Failed to Read ME7.8.8/ ME7.8 ECU Solution

Some customers have reported that when using the CG FC200 programmer to read Chery, Great Wall, Baic, Geely, Change etc ME7.8.8 / ME7.9.7 / M7.8 ECUs, the reading fails. It prompts an “E121 version not supported” error and suggests using BOOT mode. This is a tip for solving this issue.

To solve this problem, follow the steps/tips below to read/write this ECU (with the new DB15 cable):

Unplug and replug 12V power supply quickly (This is the key to solving the problem).

ME7.8.8/ME7.8 now supports Gen 2 CAN Unlock (bench mode).
Connect the CAN wires as shown in the wiring diagram.

Then hit CAN Unlock button.

Copy BMW BDC2 BDC3 Key with CGDI K2 Adapters

How to add a key to a BMW G series BDC3 module using CGDI K2 adapters—no soldering required. People generally prefer traditional soldering, but we can acquire these adapters cheaply and they work for people who prefer convenience, cleanliness, and avoiding the risk of soldering.

 

Why Use Adapters?

The adapters are described as convenient for people who don’t like soldering, don’t want to make a mess, or want to avoid the risk of damaging the original key. The CGDI K2 adapters are not free—they cost money—but they are useful.

Disassembling the Key

The process begins with disassembling the key fob. Original keys typically have small Torx screws.

• An aftermarket key
• An original key

The circuit boards of the Chinese replacement and the original keys are practically identical. Even the numbers match.

 

Preparing the Adapter

The key’s circuit board is placed into the adapter. In the CGDI K2 menu, go into “Key Adding” and select the appropriate option.

The tool shows a soldering diagram. The board matches the diagram, confirming adapter 32 is the correct one. The board is the same, so it fits.

Carefully insert the board into the adapter, warning not to force it because these are delicate components. The fit is even, with nothing forced.

Reading the Key

With everything inserted, the read function is initiated. Read and save the original key data.

Writing to the Key

Next, the type of key must be selected. Select BDC3 option. There is also an option for “board replacement only,” but it doesn’t make a difference because it can be changed later. The adapter can sometimes be tight to remove from one of the clips, so it shouldn’t be forced.

The file is written. The contacts need to be adjusted slightly so they fit properly, and the clips go in easily. The adapter is connected, and the process continues. A message appears indicating the old data will be cleared. Writing takes a bit longer, as seen. The file is written successfully.

At this point, a key has been added to a BMW G-series with BDC2/BDC3 and several other key types. The adapter set includes three adapters for different BMW types.

With the adapters, the process is convenient.

What Tool to Correct Mileage for New Volvo SPA Models?

In Volvo SPA platform vehicles (XC90, XC60, S90 etc), mileage data is synchronized across all relevant modules throughout the vehicle.

Synchronization risk: The SPA platform’s mileage synchronization logic is highly stringent. Should a replacement instrument cluster (DIM) contain a mileage reading higher than the vehicle’s current stored value, the system will automatically overwrite and synchronize all modules to the higher mileage figure. This action is irreversible and cannot be rolled back.

 

Mileage data is synchronized among 4 electronic control units. The system defaults to and displays the highest mileage value among the 4 modules. Therefore, all 4 modules must be disassembled and modified to ensure consistency.

 

Disassemble 4 modules:

DIM: MB9DF126
CEM: SPC5748
VCM: SPC564B

Airbag/SRS: P32221372

Precautions for Module Removal:

• Do not remove or install modules while the vehicle is electrically live. 

• The battery is located under the spare tire in the trunk. Disconnect both the positive and negative terminals of the battery.

Remove the airbag module (SRS) – The airbag module is located beneath the center armrest/center console.

Remove the body control module (BCM/CEM) – The body computer is located on the left side under the steering wheel.

Remove the instrument cluster (DIM) –

Note: The dashboard trim panel at this location overlaps/presses against the instrument cluster housing. The center console (center stack) must be removed first to access and release the cluster.

Remove the gateway module (CGW) – The gateway module is located under the front passenger footwell/carpet area. It may also be located on the right side of the trunk.

The mileage can be adjusted by reading the data from each of these modules individually.

What tool can be used for mileage adjustment?

OBDSTAR won’t do it.

SMOK can.

Additionally, CG100X is scheduled to release a new firmware/software update shortly that will add mileage adjustment support for these new-generation Volvo models.
