The Real Kit, In Plain English
Great for diagnostics of the Honda E.S.P. computer shift system — it quickly isolates a mechanical problem from an actual electric sensor or computer problem.
The kit runs on sealed waterproof 5-pin relays, the same style you can pick up at any local auto parts store. One relay powers the upshift, the other controls the downshift — if one ever fails years down the road, you're minutes and a few dollars from back on the trail.
It bypasses the angle sensor, speed sensor, shift computer (ECU), forward/reverse sensor and most of the main wire harness — converting your electric shift to manual-style control without computers or sensors, while you keep shifting with the stock thumb buttons.
Built from high-quality materials to withstand the toughest riding conditions — a no-fuss upgrade that saves you time, effort and money in the long run.
Recon 250 ES Shift Codes (2005–2011)
When the electric shift faults on a 2005–2011 Recon 250 ES, the “1st” gear position indicator blinks a problem code. These codes and steps are verified from the Honda 2005–2011 TRX250TE service manual. For 2002–2004 and 2012–2019 Recon ES models, check the Honda service manual for your year. The 2019 Recon has a digital gear display, not separate gear lights. Count the flashes:
| Flashes | System | Check first |
|---|---|---|
| 1 | ECU writing / recording circuit | ECU |
| 2 | Shift switch system (up/down) | Left handlebar shift buttons, wiring, or ECU |
| 3 | Angle sensor system | Angle sensor (or incorrectly installed), wiring, or ECU |
| 4 | Gear position switch system | Gear position switch, wiring, or ECU |
| 5 | ECU motor driver circuit | ECU, or the wiring to the shift motor |
| 6 | ECU fail-safe relay circuit | ECU |
| 7 | ECU voltage conversion circuit | ECU |
| 8 | Angle sensor system | Angle sensor, shift motor, wiring, or ECU |
| 9 | Angle sensor system (short or open) | Angle sensor, wiring, or ECU |
| 10 | Ignition pulse generator system | Pulse generator or wiring |
| 11 | Vehicle speed sensor system | Speed sensor, wiring, or ECU |
| 12 | Gear position switch system | Gear position switch, wiring, or ECU |
Recon 250 ES (2005–2011): How to Read, Erase and Reset Codes
From the Honda TRX250TE service manual. Erasing the stored codes clears the ECM (shift computer) memory.
- Check battery voltage first (Honda lists 12.4V minimum) and check for blown fuses.
- Turn the ignition switch OFF.
- Put the transmission in neutral.
- Apply the parking brake so the ATV does not move.
- Push and hold both the upshift and downshift buttons.
- While holding both buttons, turn the ignition switch ON. Make sure the neutral indicator comes on to show the transmission is in neutral.
- Wait 5 seconds, then push both buttons again and hold them for at least 3 seconds. The “1st” gear indicator starts blinking the problem code.
- To erase the codes (reset the ECM): while the code is blinking with the transmission in neutral, push both the upshift and downshift buttons.
- Turn the ignition switch OFF.
Recon 250 ES (2005–2011): How to Count the Flashes
Every blink is a quick flash (about ¼ second). There are no long blinks on this model. Count the quick blinks in each group. That number is the code: 3 blinks is code 3, 12 blinks is code 12. A 1-second pause comes before each code. The latest problem code shows first, then the older one, then a 2-second pause before the pattern repeats. The blinks show on the “1st” gear indicator light.
A code points to a circuit, not a guaranteed bad part. Most of the time it is a wiring problem: a stick pulled a connector loose, or water got into a plug. Check battery voltage (12.4V minimum per the Honda manual), then the connectors and wiring for that circuit, before you buy parts. Turning the key OFF and back ON also resets the ES system, but if the ECM still sees the fault it shuts the electric shift down again and blinks the code. Disconnecting the battery for a while can sometimes reset it too.
