starting issue

2000 EX with 7.3 diesel 234000 miles. After several attempts to start the battery is to low and I get code 1670. I can jump it with a charger and it starts. Checked the battery cables and pulled the starter and had it checked at Advance. All checked ok. Don't know where to go from here. I think the 1670 code points to the IDM.
thanks for any help

In this case, the P1670 probably points to the battery voltage dropping too low for the IDM to stay on line while cranking. Have you had the batteries load tested? Checked all terminals and ground connections?

Sounds like a bad connection somewhere to me if the batteries and starter are ok.

Check for corrosion and broken cables/wires.
