so I have tuned the truck had the IMMO done and loaded the vats on file but the security light stays on. we have tried using both sets of keys to remote start manual start and shut down truck. the truck runs and drives fine just have the stupid message pop up and the security lights stays on, no related codes show up. anyone got any ideas?
debating just buying a knockoff mdi and doing the procedure myself to be sure. the shop i had the IMMO done at thinks its the ECM that was upgraded instead of an exchange done.
