Toyota 1KZ ECU Repair Service
Common Overdrive & Starting Faults

This is a repair service for Toyota 1KZ engine ECUs, which are known to fail with issues such as:

  • Overdrive not engaging

  • Intermittent or complete no-start conditions

These failures are typically caused by aged or leaking electrolytic capacitors, which damage the PCB over time.

Our Repair Process Includes:

  • Chemical removal of conformal coating using a controlled hot bath

  • Desoldering and replacement of all electrolytic capacitors with equal or higher-spec components

  • Track repair and restoration where corrosion or leakage has caused damage

  • Re-coating the ECU with a clear, protective conformal layer

  • Oven bake curing for long-term durability

  • Full reassembly and bench testing

This process restores the ECU’s reliability and avoids the cost and complexity of replacement or reprogramming.
