FICM Replacement question
Ok, so this morning i checked my ficm.. cold outside truck takes 10-15 mins to start. ficm voltage at 22.7v in the on/starting position.(replace FICM). my question is I have a min/maxx tuner in the truck, do i need to have the new FICM reprogrammed. the place i ordered it from said they will load it based off my VIN number then ship it to me, however with the tuner do i need to go back to the shop that installed the H&S min/maxx and have it reprogrammed again.

Use ficmrepair.com. If you have time to send yours in they can repair it and send it back to you or they have an exchange program where you can buy one already repaired and ship yours back when you get the new one. It will be programmed already so no need to have it flashed. As for your tuner it more than likely is programming the PCM only and not the FICM. With the 22v at start up your FICM is done
You also need to check your charging system to make certain it’s working correctly and load test the batteries individually. The 6.0 is very electrical sensitive.
