Definition

Module repair is the process of restoring damaged or malfunctioning electronic control units (ECUs) to full working condition.

It involves diagnostics, component replacement, circuit rework, and final testing to ensure reliability.

  Common Repairs

• Component replacement (ICs, transistors, capacitors)

• Solder joint reflow and connector repair

• Corrosion and water damage restoration

• Processor and memory circuit fixes

  Repair Process

1. Diagnostics & Fault Finding — Identify defective components and signal anomalies

2. Component Replacement — Remove and install new parts with precision soldering

3. Circuit Board Rework — Restore damaged traces and clean oxidation

4. Final Testing — Verify voltage levels, communication, and functional performance

  Tools Used

• Soldering and hot‑air rework stations

• Microscope inspection and thermal imaging

• Oscilloscope and automated test systems

• Bench power supply and diagnostic interface

  Why It Matters

Repairing modules extends the life of vehicle electronics, reduces waste, and saves cost compared to full replacement.

Each restored ECU passes through signal integrity and load testing to ensure factory‑level performance.
