Question about 2001 Dodge Dakota
What do these mean and how to fix
P0622 is "Generator field 'F' control circuit malfunction"- your alternator has a circuit malfunction in the voltage regulator function. You need to have the charging system checked. It may be a wiring problem in the circuit to the alternator. A shop needs to test it out.
P0601 is "Internal control module memory check sum error"- I have no idea what that means, but is probably set because the charging system has a malfunction, and the result may be memory loss in the control module when the alternator acts up. Have the 0622 fixed, erase the codes, and see if the 0601 returns. That is what I would do, anyway.
