Experiencing performance issues with your Honda BeAT Fi, such as engine hesitation, reduced power, or an unstable idle? Resetting your Electronic Control Unit (ECU) might be the solution. As an essential part of your motorcycle’s fuel injection system, the ECU can sometimes benefit from a reset to restore factory default settings and clear any stored error codes. This process, often referred to as an ECM reset, can be performed manually without specialized tools in many cases, helping to revitalize your scooter’s performance.
This guide will walk you through the simple steps to manually reset the ECU and Diagnostic Trouble Codes (DTC) on your Honda BeAT Fi. This procedure is designed to bring your fuel injection settings back to their original factory parameters, which can be particularly useful if you suspect issues stemming from electrical glitches, sensor malfunctions, or after performing maintenance that might affect the engine management system.
Before we begin, it’s important to understand why you might need to reset your ECU. The ECU, or ECM (Engine Control Module), records various operational data from your motorcycle. This includes instances where the bike might have encountered problems like a fall, battery issues, disconnected sensors, or even wiring problems. Resetting the ECU clears this memory, effectively giving your motorcycle a fresh start in terms of its electronic management system.
This manual reset procedure is applicable for various Honda BeAT Fi models, including both non-ESP and ESP versions, and may also be relevant to other Honda scooters and underbone motorcycles that utilize similar fuel injection systems. Performing this reset can often restore engine performance and smooth out irregularities.
Step-by-Step Guide to Resetting Your Honda BeAT Fi ECU
Part 1: DLC Jumpering and Initial Reset
First, locate the Data Link Connector (DLC) on your Honda BeAT Fi. Typically, on this model, the DLC is situated beneath the seat. You will need to remove the engine cover and the seat base box to access it. Once located, disconnect the DLC connector. Refer to the image below for visual guidance.

Ensure the ignition is switched off. Using a jumper wire, connect the brown wire terminal to the green or black wire terminal within the DLC connector.
With the DLC jumped, turn the ignition key to the “ON” position. Wait for approximately three seconds, and then disconnect the jumper wire from the DLC.
After disconnecting, wait for another five seconds, and then reconnect the jumper wire to its original position in the DLC.
Observe the Malfunction Indicator Lamp (MIL) on your dashboard. If the reset is successful, the MIL should blink rapidly, similar to the turn signal indicator. At this point, you can switch the ignition to the “OFF” position.
Part 2: ECU Reset Procedure
Ensure the jumper wire remains connected from the previous step. With the ignition off, fully open the throttle and hold it in the wide-open position.
Turn the ignition key to the “ON” position while still holding the throttle open. Wait for the MIL to blink.
Release the throttle immediately when the MIL starts blinking. Allow the motorcycle to sit for about three seconds, then turn the ignition to the “OFF” position.
Disconnect the jumper wire from the DLC. The ECU reset procedure is now complete.
After completing these steps, attempt to start your Honda BeAT Fi. You should notice improved engine performance if the reset was necessary. If the MIL continues to blink after the reset, inspect the motorcycle’s wiring and connectors for any loose connections or damaged wires. A persistent MIL indication might suggest underlying mechanical or electrical issues that require further diagnosis beyond a simple ECU reset.
This manual ECU reset method offers a straightforward way to potentially resolve common fuel injection related problems on your Honda BeAT Fi. By following these instructions, you can attempt to restore your scooter’s performance efficiently and effectively.
