How to Test to See if the Module is Bad on the T-One # 118521 for a 2014 Honda Odyssey

Question:

I have the T-one 118521 wiring harness on my 2014 Honda Odyssey and it stopped working after my last use. There are no blown fuses I can find anywhere. Is it possible that the converter module is not working?

It is possible that the module on your Tekonsha T-One # 118521 for your 2014 Honda Odyssey has gone bad. You can verify this by using a Circuit Tester, like part # PTW2992, and testing the wiring on both sides of the converter to see if power is getting through or not.

If it isn't then you will want to replace the T-One. I recommend replacing it with the same part as we have found the Tekonsha electronics to be very reliable. If you are getting power from the functions to the 4-Way let me know and I can help you troubleshoot further.
