If you own a Honda Foreman 500, then you know that it is a powerful and reliable workhorse. But even the most well-made machines sometimes need a little help to get back on track.
In this article, we will share all of the trouble codes (DTCs) for the Honda Foreman 500, so that you can easily diagnose the problem and get your ATV back on the trails. Let’s get started!
Retrieving Trouble Codes on the Foreman 500
Usually, we use an OBD2 port to connect to the vehicle in order to retrieve fault codes and troubleshoot a problem, however, that is not the case with the Foreman 500 as there is no OBD2 port.
Instead, the Foreman 500 provides trouble codes by blinking the corresponding indicator light on the dash when the ignition is on. Normally, all of the lights on the dash stay on for a second or two to give you a chance to see if any of the bulbs in the dash are out. However, if there is a fault code stored in the EEPROM, then after the dash lights go out, one or a few of them will start blinking.
For example, if the EPS indicator light is blinking, then it means that your Foreman 500 has a malfunction with the Electric Power Steering system and a DTC (Diagnostic Trouble Code) is stored.
It’s pretty easy to read stored fault codes, as the blinking system is easy to understand.
The indicator lights can either blink for 1 second (long) or 1/4th of a second (short). A single long blink stands for 10, while a single short blink stands for 1.
Let’s say that the EPS light blinks long two times and then follows with four short blinks. The two long blinks stand for 20, while the four short blinks stand for 4. Now you have to add them together and get 24, which can be found in the DTC list below. It stands for an Engine Speed Signal malfunction.
Now, there is no gear indicator light on the dash, but the LCD screen on the dash shows which gear is currently selected. When a fault code is stored in the ESP (Electric Shift Program) or the DTC, then the number of the currently selected gear will be replaced by a dash (-) and then the dash will be used to blink out a DTC.
Note: All of the troubleshooting processes for each of the fault codes can be found in the owner’s manual of your specific Honda Foreman 500.

Looking for a carb for a Honda 500 .. vin # ?HFTE31T9B4600624. CHEERS MATT. I THINK I AM MISSING FIRST DIGIT OR LETTER?
Hi Matt,
You are indeed missing the first digit or letter, so VIN is no use right now. Try searching by year and confirming that the carb looks similar visually, or contact hondapowersportsparts.com for help if you want OEM.
