Installation Requirements
This Engine Control Module (ECM/PCM) is a direct replacement, pre-programmed to your VIN, but it requires immobilizer relearn (key programming) after installation.
To complete installation, you will need one of the following:
- An automotive locksmith
- A key programming tool or advanced scan tool (capable of performing immobilizer/key relearn)
In many cases, you will also need to perform a crankshaft variation relearn to clear codes such as P0315 / P1336. This procedure also requires a capable scan tool.

-
VIN required – Provide your 17-digit VIN at checkout or by message so we can program the ECM.

Know before you buy – You will need access to key programming equipment or a professional locksmith.
