CAN Network Isolation & Termination Kit

Currently backorder due to DECS-04, no ETA as of now.

When a vehicle has a dead or unstable communication network, guessing can cost hours. This kit gives you everything you need to isolate bad modules, restore proper CAN termination, and bypass damaged wiring so you can prove the failure instead of chasing it. Whether you are dealing with a total no-comm situation, intermittent network dropouts, or setting up a bench test, this bundle lets you control the network and quickly narrow the problem to a module, a resistor, or the harness itself.

By combining proper termination, controlled module isolation, and full harness bypass capability, this kit removes the guesswork from CAN diagnostics. 

Bundled Kit includes

2x 16-R-120 – 120Ω CAN Resistor Leads: Restores proper CAN bus termination when a resistor is missing due to an unplugged module or damaged wiring. These plug directly into your breakout box or test leads using standard 4mm banana connections. Use one for a single missing resistor or both for full bench setup and dual-end termination.

1x uBypass Overlay Harness: A 15 ft twisted-pair network bypass cable used to completely bypass suspect vehicle wiring or a problematic section of the harness. Safety banana plugs on both ends allow quick connections using terminal adapters or test leads.

1x DECS-04 – uIsolate Network Isolator Kit: Allows you to isolate modules one at a time on CAN, GM Class 2, and other 1-wire and 2-wire networks. Add modules back into the network in a controlled way to quickly identify the module that is pulling the network down. The included large and small terminal splice packs connect directly to most common diagnostic connectors.

What this kit is used for?

• Diagnosing no-communication vehicles
• Finding modules that are shorting or locking up the network
• Restoring missing CAN termination resistance
• Bypassing damaged harness sections
• Bench-testing vehicle networks
• Proving whether the fault is wiring or a control module
• Verifying network health before replacing expensive modules
