Xhorsevvdi.com engineer tested using Xhorse VVDI Key Tool Plus to read BMW CAS4 1L15Y key information on the bench with Godiag GT100 ECU Bench Connector and Godiag CAS4 & CAS4+ test platform.
First of all, watch youtube video:
Then have an overview of the above tools:
1L15Y module: it is dismantled from the car.
VVDI Key Tool Plus: it is able to read the BMW CAS4 key information and automatically display the ISN code, so we just need to connect CAS4 module to vvdi key tool plus to program key. If no ISN code, we need engine or key to obtain ISN first.
Godiag GT100 Bench ECU connector: by connecting to VVDI Key Tool Plus, it is able to supply power to it, and it is able 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: to tell if the key works after programming because the CAN indicator will flash. So far, it is only compatible with GT100, in the future, it will be working with more devices.
Here we go, the whole job will be done on Bench.
Step 1. Hardware and cable connection:
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.
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.
Good to know: when the Xhorse VVDI Key Tool Plus is communicating with CAS4 module, GT100 CANH and CANL indicator will flash.
Select ” Read” Key information.
When it is reading, the GT100 CANH and CANL indicator will flash too.
Alright, the key information is read out.
Here are 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 VVDI Key Tool Plus read BMW CAS4 key information on bench with Godiag GT100 and CAS4 /CAS4+ Test Platform.
