Default Codes b1121 and b1122

Ive taken my 01 softail to the tech and I have fault codes B1121 and B1122, which are

B1121(TSM) Left Turn Output Fault
B1122(TSM) Right Turn Output Fault
all the bulbs are working so I can only think there is a short to ground ,is this correct ???, or is there something else causing this problem , when I use thr indicators they flash normal for 4 seconds the flash at a more rapid pace , I am lost on what is causing this and where to start..any help would be grateful , Cheers.

Looking at my 2009 electrical manual ... I know not really the same codes because according to my manual b1121 and b1122 are "will not flash"

What they mention first is to check for corrosion/bad contacts among the terminals and bulbs, clean them and apply electrical contact lubricant ...

Do they still auto-cancel after 20 something flashes when you are riding? If they don't is indication of TSM module on the way out ...

Guess you need to get your hands on a 2001 electrical manual.

Did you just switch to LED turn signals by the way? I did and I am getting the same error with the red key. I ordered a Load Equalizer from Kuryakyn, should solve my problem.

so I have these fault codes I've changed the indicators but I changed to bulb indicators and they seem to flash normally for 4 seconds and then really fast I'm not too sure what to do. Do I need to get different bulbs the original indicators were bulbed indicators
