If you have a DMM you can do voltage checks at the alternator, battery, etc.
I would start with the battery while the car is off. Make sure your terminals at least look clean, not covered up with corrosion.
If you're getting at least 12v at the battery I'd proceed with further testing. If you're not, start by either charging the battery or having it load tested.
Another spot to check is where the positive cables land at the fuse box right in front of the battery. Mine had some oily gunk on them preventing good connection that was causing voltage to read a hair low, just enough to start causing problems.

Very good suggesting and often overlooked. Other areas are the grounds.
Possible bad ignition switch contact…DIC voltage is taken from the Ignition 1 voltage signal going to the IPC…if you know how to use a DMM connect one lead to battery positive and other lead to IPC fuse 19 when you are seeing 7 volts… you will probably be reading 6 volts or so on the DMM…you are dropping 6 volts across the switch contacts.
