Step 1. Hardware and cable connection: prepare one VVDI Key Tool Plus, Godiag GT100, Godiag BMW CAS4 & CAS4+ Test Platform, one BMW CAS4 key and BMW CAS4 module. Then connect them as shown in this video.
Step 2. Turn on GT100 power button and 12V button.
Step 3. Put a CAS4 Key into the hole of the test platform, then press the switch button, the dash indicator will turn blue.
Step 4. On VVDI Key Tool Plus, tap “IMMO Programming” -> Europe ->BMW ->Automatically diagnose models -> Connecting to CAS system -> Generate keys via OBD -> Program key and more.
Look at the image below, do you know what kind of equipment they are? What can they do? Let me answer your question, from top to bottom, they are Godiag GT100 Bench ECU connector, Godiag BMW CAS4 & CAS4+ Test Platform, Xhorse VVDI Key Tool Plus and BMW CAS4 1L15Y Module. uobdii.com engineer already successfully used them together to read CAS4 1L15Y key with 315Mhz frequency.
A brief introduction of the above tools:
Godiag GT100 Bench ECU connector: used to supply power to VVDI Key Tool Plus, to tell if the CAS4 module has a good communication with Key Tool Plus because the indicator will flash.
Godiag BMW CAS4 & CAS4+ Test Platform: it will tell if the key is programmed to be working.
VVDI Key Tool Plus: you can automatically identify the BMW CAS4 key information and then program the key.
CAS4 module: it is removed from the car.
So the whole job will be done on Bench. Let’s go.
Use 16pin cable to connect VVDI Key Tool Plus and Godiag GT100;
Supply power to Godiag GT100;
Connect Godiag BMW CAS4 & CAS4+ Test Platform to GT100;
Connect BMW CAS4 module to the test platform.
Turn on GT100 power button and 12V button.
Put a CAS4 Key into the hole of the test platform, and then press the switch button, the dash indicator will turn blue.
Go to VVDI Key Tool Plus to tap “IMMO Programming” -> Europe ->BMW.
Select “Automatically diagnose models” and read the function description to follow, tap “Continue”.
Connecting to CAS system.
The current system type is detected as CAS4 1L15Y. About to enter the system operation interface, please wait…
As you can see, when the VVDI Key Tool Plus is communicating with CAS4 module, GT100 CANH and CANL indicator will flash.
Select “Generate keys via OBD”, another option is “generate keys via EEPROM”.
There are several function menus shown as below, we choose ” Read” Key information.
When it is reading, the GT100 CANH and CANL indicator will flash too.
Okay, the key information is read out.
Next go forward to do what VVDI Key Tool Plus can do including: unlock CAS4/CAS4+, prepare dealer key with ignition switch, prepare dealer key with programmer, read ISN from original key, CAS4(5M48H, 1N35H) fix start, fix remote/smart function, OBD read D/P and exchange CAS4, Erase key, enable key, disable key, upgrade CAS4/CAS4+ original file, reset FEM to start, close transponder mode.
Alright, this is on how does Godiag CAS4 /CAS4+ Test Platform work with GT100 & VVDI Key Tool Plus.
