Note: To learn and verify the key, install the BDC2 in the car or use a test bench ( for BCD2 Test Platform). This greatly simplifies the workflow and avoids the many power supply and communication requirements and limitations associated with performing programming operations directly on the car. Additionally, if there is an issue with the BDC during the key programming process that requires online coding or initialization, the operation can be performed directly on the platform without connecting it to the vehicle. Directly check the fuse connectors on the vehicle without repeatedly disassembling the BDC for inspection.
