Buyer's checklist
What to check before buying a used engine computer
- Match the hardware part number and catch code exactly, as internal board architecture varies even within the same vehicle year and engine family.
- Confirm security anti-theft (PATS, PASS-Key, or Immobilizer) pairing requirements, as used ECMs almost always require VIN programming before starting the vehicle.
- Inspect connector headers for bent pins, thermal discoloration, or green corrosion indicating water leakage through the wiring harness plug.
- Verify emission tier compatibility (Federal/EPA vs. California CARB standards) and transmission control integration (PCM vs standalone ECM/TCM).
