Looks like a call to swamps but what about the balance fault?

I wouldn't worry too much about the balance fault code, unless it returns with the new FICM

x2 on the FICM. Fix that and every thing else will probably go away. Have you checked your FICM voltage?

This would also be a good time to load test your batteries and alternator. Don't want to screw up a brand new FICM.

x3 Replace the FICM, first and foremost. The P06** glow plug circuit DTCs will likely require either the GPCM or the corresponding glow plugs, along with two new glow plug harnesses (since removal will damage them with 95% certainty).
