ECM/PCM Repair & Replacement
Service Overview
The ECM/PCM Repair & Replacement service helps restore proper engine performance by diagnosing, repairing, or replacing faulty Engine Control Modules (ECM) and Powertrain Control Modules (PCM). These critical control units manage essential vehicle functions such as fuel injection, ignition timing, emissions control, transmission communication, and overall engine operation. A malfunctioning ECM or PCM can lead to poor performance, warning lights, starting issues, or complete engine failure.
At Car Code Solutions, we provide professional ECM/PCM Repair & Replacement for a wide range of European, Domestic, and Asian vehicles. Our technicians use advanced diagnostic equipment and manufacturer-approved programming procedures to accurately identify module failures, repair damaged control units when possible, or replace them with new or donor modules that are correctly programmed and synchronized to your vehicle. Every service is performed with precision to ensure reliable operation, compatibility, and long-term performance.

Vehicles We Cover
ECM/PCM issues split into two different jobs: board-level repair (fixing corrosion, blown circuits, or failed components on your existing module) and full replacement with programming/cloning onto a new or used unit. Which one applies depends on the failure — we diagnose that first. Covers the makes below. Not sure about yours? Ask us.
