- What is the Delphi Cars & Trucks 202110B update? The 202110B update is the latest firmware release from Delphi, designed to enhance the performance and functionality of their Cars & Trucks system.
- What is the MHH Top platform? The MHH Top platform is a critical component of the Delphi Cars & Trucks system, designed specifically for heavy-duty vehicles, such as trucks and buses.
- What are the benefits of the 202110B update? The update offers several benefits, including improved diagnostic accuracy, increased efficiency, and enhanced vehicle coverage.
- Protocol Stability: It refined the timing for the ISO 15765-4 CAN protocol, ensuring faster handshake speeds with modern ECUs.
- Hardware Protection: Updates like 3201 often contain logic to prevent voltage spikes during the ignition cycle, protecting the VCI hardware and the vehicle's sensitive electronics.
- Bootloader Compatibility: For the software to recognize the VCI, the firmware on the device must match or exceed the version required by the software. The 2021.10b software specifically mandates firmware capabilities found in the 3201 suite to unlock the full range of 2021 vehicle protocols.
