This post will perform to read BMW engine control module B48 ISN code via OBD way using Autel MK808TS.
Step 1: Connect Autel MK808TS with car via OBD port, enter car model “BMW”, and choose “smart mode” in mode selection.
Step 2: Choose “DME engine system”, the device system will identify the current engine model: DME8FF_R.
Step 3: Select “read ISN”, This function requires networking, please ensure that the network is normal. There is a certain risk in reading the engine ISN code, and programming is required, need to ensure that the power supply voltage is stable and exceeds 13V.
Step 4: The device will detect whether the current engine version supported to read ISN. If the current version support, it will jump to the payment interface.
Step 5: After making the payment, click OK. The device back up the coding file then download the configuration file. (Make sure the network is working when downloading files.)
Step 6: Downloading the configuration file complete, Click “ok” to enter the programming operation, which is divided into five parts. It takes about 50 minutes. Some models may take longer.
