Diesel ECM / ECU Test Kit – Bench & On-Engine Diagnostic Leads

Do you test control modules found in diesel engines like PACCAR, Detroit Diesel, Caterpillar Inc., or Volvo Trucks?

Whether you need to bench test, program, or diagnose directly on the engine — without struggling to probe pins using aftermarket leads — you’ve come to the right place.

At ERD Powertrain, we specialize in wire harness repair kits and OEM-style diagnostic contacts that properly mate with factory ECU and ECM connectors. That means:

✔ No damaged terminals
✔ No unreliable back-probing
✔ No loose aftermarket pins
✔ Accurate and professional testing connections

Don’t wait. Get the right connectors and start testing the right way.
