Additional Info

Here’s a detailed guide on the Toyota Aygo MK1 (KGB10R) ECU, covering its functions, installation, precautions, fault codes, fault code clearing, and fitment in the vehicle.


1. ECU Overview

ECU Part Numbers:

  • 89661-0H022 / 0261208702 / 0 261 208 702
  • Bosch ECU
  • Engine: 1.0L 1KR-FE (998cc, 67bhp)
  • Transmission: 5-Speed Manual
  • Model Years: 2005, 2006, 2007, 2008
  • Vehicle: Toyota Aygo MK1 (KGB10R) VVT-i PLUS, Petrol, 57 Reg

ECU Functions:

The Engine Control Unit (ECU) is responsible for monitoring and managing various aspects of the engine and vehicle performance, ensuring fuel efficiency, emissions compliance, and reliability.

  1. Fuel Injection Management

    • Controls electronic multi-point fuel injection (MPFI).
    • Adjusts the air-fuel ratio for different driving conditions.
  2. Ignition Timing & Spark Control

    • Regulates ignition timing for efficient combustion and power output.
  3. Variable Valve Timing (VVT-i) Control

    • Adjusts the intake camshaft timing for better fuel economy and performance.
  4. Idle Speed & Throttle Control

    • Works with the electronic throttle body to control idle speed.
    • Manages throttle response based on driver input.
  5. OBD-II Diagnostics & Monitoring

    • Continuously monitors sensors and actuators.
    • Stores DTCs (Diagnostic Trouble Codes) when malfunctions occur.
  6. Emissions Control System

    • Works with oxygen sensors and catalytic converter to reduce emissions.
    • Ensures compliance with Euro 4/5 emissions standards.
  7. Engine Load & Performance Management

    • Adjusts fuel delivery and ignition timing based on engine load, RPM, and temperature.

2. Installation Process

Pre-Installation Precautions

  • Disconnect the 12V Battery: Prevents electrical damage and resets ECU memory.
  • Use Anti-Static Protection: Wear an anti-static wrist strap to avoid damaging sensitive ECU components.
  • Verify Part Number Compatibility: Ensure the replacement ECU matches the original unit.

Installation Steps

  1. Locate the ECU:

    • Typically found under the dashboard, near the glove box, or in the engine bay.
  2. Remove the Old ECU:

    • Unplug all electrical connectors carefully.
    • Unscrew the ECU from its mounting bracket.
  3. Install the New ECU:

    • Secure it in the correct mounting location.
    • Reconnect all wiring harnesses.
  4. Reconnect the 12V Battery.

  5. ECU Reprogramming & Immobilizer Adaptation:

    • Some ECUs require Toyota Techstream software for programming.
    • Immobilizer adaptation may be needed if replacing the ECU.
  6. Test the System:

    • Perform a diagnostic scan using an OBD-II scanner to check for errors.
    • Ensure smooth engine startup and idle.

3. Precautions

  • Avoid Water Damage: The ECU should be kept dry to prevent short circuits.
  • Secure Connectors Properly: Loose connections can cause communication failures.
  • Match Software & Hardware Version: A mismatched ECU may require reprogramming.

4. Fault Codes (DTCs) & Troubleshooting

The ECU stores DTCs (Diagnostic Trouble Codes) when it detects malfunctions. Below are common fault codes:

DTC Code Description Possible Causes
P0171 System Too Lean (Bank 1) Vacuum leak, faulty O2 sensor, fuel delivery issue
P0300 Random Cylinder Misfire Faulty ignition coil, spark plugs, fuel injector issue
P0420 Catalyst System Efficiency Below Threshold Faulty catalytic converter, oxygen sensor
P0106 Manifold Absolute Pressure (MAP) Sensor Issue Faulty MAP sensor, wiring problem
P0113 Intake Air Temperature (IAT) Sensor High Input Damaged IAT sensor, loose wiring

5. Clearing Fault Codes

After resolving the underlying issue, follow these steps to clear the DTCs:

Using a Scan Tool (Toyota Techstream or OBD-II Scanner)

  1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
  2. Turn the ignition ON (without starting the engine).
  3. Scan for error codes using Toyota Techstream or an OBD-II scanner.
  4. Select "Clear Codes" to erase stored DTCs.
  5. Restart the engine and verify that no warning lights reappear.

Manual ECU Reset (Battery Disconnect Method)

  1. Disconnect the 12V battery (-) terminal.
  2. Press and hold the brake pedal for 30 seconds (to discharge stored power).
  3. Reconnect the battery and turn the ignition ON.
  4. Start the engine and check for any warning lights.

6. Fitment in the Car & Communication with Other Modules

ECU Location:

  • Typically found under the dashboard or in the engine bay.

Communication with Other Modules:

The ECU communicates via the CAN Bus system with:

  1. Instrument Cluster – Displays engine warnings and diagnostics.
  2. ABS & Traction Control System – Manages engine power during wheel slip.
  3. Immobilizer (IMMO) – Ensures only authorized keys can start the car.
  4. Throttle Body & Sensors – Adjusts throttle response and fuel injection.
  5. Airbag Module – Works with engine management during crash situations.

Engine Control Function The engine control function is primarily handled by the Engine Control Unit (ECU) or Engine Control Module (ECM). It’s the computer or electronic system responsible for managing and optimizing the performance of the engine in modern vehicles. The ECU/ECM controls various engine functions by adjusting inputs such as fuel injection, ignition timing, air-fuel ratio, and more.
