Modul 13 - Mereset ECM

Summary

This video explains how to diagnose and reset the Malfunction Indicator Lamp (MIL) on a Honda motorcycle. It guides viewers through reading the MIL blink codes to identify issues with the fuel injector and throttle position sensors. The process includes inspecting and repairing faulty sensors, verifying the repairs by checking if the MIL still flashes, and then resetting the Engine Control Module (ECM) using an SCS connector to clear stored error codes. The tutorial emphasizes careful handling of the Data Link Connector and confirms the reset by observing constant MIL blinking, ensuring the motorcycle’s injection system is fully functional and error-free.

Takeaways

• 😀 Start by detecting the MIL (Malfunction Indicator Lamp) blinking pattern on a Honda motorcycle to identify error codes.
• 😀 Observe the number and pattern of blinks to determine the error type (e.g., long blinks and short blinks).
• 😀 A blinking pattern of 10 and 12 indicates a problem with the injector sensor and throttle position sensor (TPS).
• 😀 Turn off the ignition key and inspect the components (sensor and TPS) related to the MIL error codes.
• 😀 After repairs, turn on the ignition again to check if the MIL light continues to blink.
• 😀 If the MIL light no longer blinks, the injection system has been repaired successfully.
• 😀 To clear the error history, turn off the ignition and remove the DLC (Diagnostic Link Connector) cover.
• 😀 Ensure the DLC cover is correctly removed by carefully checking the connector latch.
• 😀 Use an SCS connector to reset the error codes stored in the ECM (Engine Control Module).
• 😀 After installing the SCS connector, turn on the ignition to check if the ECM still holds previous error codes.
• 😀 Reset by disconnecting the SCS connector for less than 3 seconds, then reconnecting it. A constant blinking of the MIL indicates a successful reset.
• 😀 Turn off the ignition, then turn it back on to confirm no error codes remain in the ECM.
• 😀 If the MIL remains lit continuously after resetting, there are no remaining error codes in the ECM.
• 😀 Finish the process by turning off the ignition and reinstalling the DLC cover.

Q & A

What is the first step in checking the MIL (Malfunction Indicator Lamp) on a Honda motorcycle?

The first step is to turn the ignition key to the ON position and observe the MIL blinking pattern to detect any error codes.

How do the MIL blinking patterns help in diagnosing the motorcycle's issues?

The blinking patterns, which consist of long and short blinks, correspond to specific error codes that indicate which components, like the injector or throttle position sensor, may be malfunctioning.

Which sensors are commonly identified as problematic when MIL blinks are observed?

The most commonly indicated sensors are the injector sensor and the throttle position sensor (TPS).

What should be done after identifying the faulty components from the MIL codes?

The ignition should be turned off, and the faulty sensors or connectors should be repaired or replaced before checking the MIL again.

Why is it necessary to check the MIL after repairing the components?

To confirm whether the system has been fixed, because if the MIL does not blink after repair, it indicates that the injection system is functioning properly.

What is the purpose of the SCS connector in this process?

The SCS connector is used to reset the ECM (Engine Control Module) and erase the stored error codes after repairs have been completed.

Describe the correct procedure for resetting the ECM using the SCS connector.

First, turn off the ignition and open the DLC cover. Connect the SCS connector, turn on the ignition to read stored codes, then remove the connector for less than 3 seconds and reconnect it. If the MIL blinks continuously, the reset was successful.

How can you confirm that the ECM reset was successful?

After performing the reset, if the MIL blinks continuously in a constant manner without turning off, it indicates that no error codes remain in the ECM and the reset was successful.

What is the final step after successfully resetting the ECM?

Turn off the ignition, remove the SCS connector, and reinstall the DLC cover to complete the reset process.

Why is it important to reset the ECM after repairing sensors or components?

Resetting the ECM clears the stored error codes and ensures that the system does not display old faults, providing an accurate reading of the current system status.
