Harley DTC

useless application don't waste money

Must not be supported anymore, because there’s no iOS 11 update and it will not work anymore. I will leave it on my phone for few more weeks to see if they update the app. If not, I’ll just remove it and look up codes individually on the Internet.

Useless to me

Found none of the following information read from the vehicle. Does not appear to be updated for the newer bikes at all (In fairness I don’t have the EDM in front of me to compare it but I know these codes are for fan voltages/cooling for the newer bikes so. . .) Money is better spent ordering the Electrical Diagnostic Manual (EDM) for your Year/Model bike. Nice concept, not updated, waste of money.

Harley DTC codes

I purchased the app just today at the suggestion of my local Harley dealer. I found all the codes I needed to diagnose the electrical problem on my 2011 Heritage Softail. My only complaint is the description was not through. The app noted "low battery voltage" but I had to go online to get a complete description of my problem. The app points you in the right direction but from the information it appears someone went on coffee break and forgot to complete the data when they returned. This app has the potential to really be an asset to Harley riders. Hoping an update will correct the deficiencies.
