Issue 3: Communication Failures with Specific ECUs (e.g., Engine responds, but ABS does not) Poor quality hardware clone.
To run this software, you need a compatible OBD2 multiplexer tool. The software is tailored primarily to two hardware designs: Hardware Configuration Strengths & Stability Best Use Case
While newer versions might exist, the version is favored for its stability, comprehensive coverage of vehicles up to the 2021 model year, and active development in its "clone" form. delphi autocom 202111 c4b
The first step is to obtain the software package. As this is not an official release, it is typically found on automotive forums, file-sharing websites, or third-party marketplaces. The package for "Delphi 2021.10B + Autocom 2021.11 C4B" is often around 2.5 GB in size.
Faster Intelligent System Scan (ISS) to identify ECU faults across all modules in seconds.
