Idoit lights
When the key is in the ON position my idoit lights dont all light up like they are supposed to. Only the ones that need to light up like the car was running. Like when I open door or hatch, and e-brake light is on. But stuff like check engine, add coolant are all off. The add coolant works for sure, it went on when I was flushing system and didnt have enough in there the other day.

Either a broken wire from the Alternator to the CPU or a bad solder joint on the connector (jack) at the CPU.
Attached is a jpg of the circuit. Check that wire is connected to the alternator (small two socket plug) and that there is a ground for the relay when it latches. Also check that fuse (slim chance of it being bad). Then take the CPU apart and resolder the jack connectors (just reheat them might do).
The idea is that when the car is not turning and the key is on, a ground goes from the alternator to pull that relay in. When the relay is pulled in, a ground is sent to the idiot light cluster to illuminate all the idiot lights. Something like that anyway.
