I seriously doubt you will be able to diagnose this without a very high end scan tool and a lot of knowledge. It's a complicated system.
The switch talks to the BCM by sending varying voltage signals which the BCM interprets and then signals the IPDM to activate the function.

Hello there thank you for the response, like you said I tried to check the circuit with otc evo 5.0 scan too. when I activate the the right turn signal. all i see is the plinking arrow at the dash board. also when I check power at the connector all i see is ground and power. if you have anything to say i would appreciate. thank you.

Check for codes in both the BCM and the IPDM.

hello there thank you for the help, when I couldn't find power at the connector, I tried to find where it was lost, there was a disconnected wire underneath the fuse box under the hood. I soldered that and everything was ok.
thank you.
