SP Diagnostics manufacture a range of Uniplex adapters for use with the ACR4 and CAN Harness (30214100/302141V2).
What is a uniplex?
A uniplex is a physical adapter used to allow communication with additional CAN bus networks on certain vehicles. It is used in conjunction with the ACR4, G2 pod and CAN harness.
Why is a uniplex required?
Vehicle manufacturers have recently begun adding additional CAN bus networks to vehicles which were not present when the CAN harness was originally designed. In order to be able to access diagnostic systems that use these newer networks it was necessary to either develop a new CAN harness or produce a low cost adapter to allow the existing CAN harnesses to communicate. The latest SP Diagnostics handset (the SPi) does not require the use of any uniplex adapaters and can communicate with any CAN bus network using the single universal cable provided with the SPi.
