4lo blinking and VSC light on

Hi all, I’m new here. Been lurking for little while. Anyways I just picked up a 2012 crew max with 47000 miles. The 4hi was blinking. From research on here I tried all the tricks but in the end I put in a new front actuator. After the actuator went in the 4hi light is off but now I have the 4lo blinking and the vsc traction control light on. The truck doesn’t go into 4hi or 4lo it’s stuck in 2wd. Any ideas anyone? The check engine light is not on as many other posts here say also truck runs fine. It’s not in limp mode. I tried disconnecting the battery to reset than the srs light also came on. That went away after I turned off and restarted truck. Thanks for your help. This places has tons of info.

 

Go to your local auto parts store and have them read the problem codes for you.

 

Hi, there is no check engine light on. I have a ultra gauge that should show codes and it has no codes that come up. Should there be codes with those lights on?
