Calibration fails no error codes

Former Member over 4 years ago

Myself and many others have calibration failed issues. Is it worth buying a Garmin computer to diagnose and perhaps fix the calibration failed issue? If so which computer?

Details:

I have had the Vector 3 pedals ($1000) since July. Out of the box they worked with my Wahoo ELMT Bolt, but the calibration was off. I eventually tried to calibrate them, but after that they no longer work. The Garmin Connect app and the Wahoo Bolt, both recognize the pedals, but can't calibrate them. I just get "FAILED", no error codes and the pedals don't flash any errors.

I have brand new 2L76 batteries and washed the contacts with alcohol, but did not have mineral oil to coat them. The left pedals shows green leds when I wake it up. The Garmin Connect app has the firmware at 3.6. The app also has the right pedal led green, which I assume means the left is connect and the right is connected to the left.

There have been lots of posts, but no solutions. I am thinking of buying a Garmin computer, just to diagnose the issues, since I don't get error codes with the Bolt or the Garmin Connect app. Would the Garmin computer give the error codes and perhaps calibrate the pedals.

Vector 3 pedals should be at 3.80

I can't update to 3.80. It's at 3.60. Garmin Express does not see the pedals. Garmin Connect mobile app shows 3.6 without any option to go to 3.80. It does not recognize that a newer firmware version is available.

The update should be done either via GCM or via a compatible head unit.

Not sure why GCM is showing 3.6. What version of GCM are you using?

If you remove the device from GCM and re-add it, it should prompt GCM to query GC again for the latest software

I removed the Vector 3 pedals, then added them. When setup was done. it showed firmware as 3.8. So that was a very good suggestion. I still get calibration failed without any codes, when I try to calibrate.

Are you calibrating using the Wahoo or GCM?

Support told me to remove the pedals from the Wahoo computer, so I am using GCM and the Wahoo Elemnt Bolt is not connected to the pedals.

I will try the GCM.

I turned the power off to the phone and connected the Wahoo computer to the vector 3 pedals. FYI, the power agrees with the TACX trainer. The signal strength on the Wahoo computer is full bars. But, when I select calibrate, it pauses a little, then displays Calibration Failed, no error codes.

So did it calibrate correctly when using GCM? If it did then it sounds like the Wahoo maybe incorrectly reported a failed calibration.

Remove your trainer from Wahoo too, maybe the Wahoo wants to calibrate your trainer instead of your pedals and cant do it and fails. is the Bolt's firmware the latest? Check it with the Wahoo app. And pls try what aweatherall suggested to You, no Wahoo, just GC app and try to calibrate in that app, if that gives You good calibration value (+-0.00 or similar torque number) then the pedals are ok and the problem is at Wahoo's side
