Bench Master — Advanced Diagnostics & Solutions

Module resale

Every unit here has already proven it works.

We don't sell parts pulled straight off a shelf and hoped for. What's listed here has been through the same bench process we use for repairs — power-up, communication check, and a verified read — before it's ever offered for sale. If it didn't pass, it isn't listed.

Why buy tested
Typical used pull
No comm check. You find out if it works after it's already in the vehicle.
Bench Master unit
Power-up confirmed, communication confirmed, module ID and live data read verified.

Sequence

How buying here works

  1. Find your part number

    Cross-reference against your vehicle before reaching out — the same casting can carry different software across platforms.

  2. We confirm fit and availability

    We'll tell you plainly if it's not a match rather than sell you something that won't work.

  3. Ships tested

    Every unit that leaves here has already been bench-verified before it was listed — not after you ask.

Questions before you buy?

Send the part number and what vehicle it's going into. A straight answer costs nothing, including when the answer is that it won't work for your application.
