2012 Toyota 4Runner 4.0L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 Toyota 4Runner 4.0L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.

Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
Complete communication & CAN-bus verification
Sensor input/output and signal integrity checks
Injector & ignition pulse simulation
Power, ground, and load-circuit analysis
Flash memory integrity and checksum validation
Thermal and voltage-stress testing to confirm reliability
Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.
For a 100% plug-and-play solution, we recommend using our full cloning service. We transfer all security data to the replacement unit.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Jordan Hill –
The VIN programmed ECM arrived quickly with free shipping and was ready to install right out of the box—super convenient.
Excellent communication throughout the process, and the professional programming saved me a lot of hassle.
Fast turnaround and the updated PCM works perfectly in my 2012 4Runner with zero issues so far.
Shipping was very reasonable, and they answered all my questions promptly, making the whole experience stress-free.
Plug-and-play setup made swapping the ECM straightforward, and the quality is top-notch.
