When a code P0688 is stored, it means that the powertrain control module (PCM), has detected an abnormality in the relay which supplies it with voltage.
code p0622 refers to alternator ,field control-circuit malfunction causes--wiring ---alternator---battery---ECM. I would have the battery load tested first to check for loose for terminals and failing cells. Then check that the plug in the back of the alternator is tight
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.
DTC P0622 - Generator Field Control Circuit This is a trouble code relates to the charging system and means that the Powertrain Control Module is trying to control the generator field with no result during monitoring.
This problem could be caused: - open/shorted within the field control circuit between the PCM and the alternator ( a brown/gray wire ), - generator ground circuit (brown/black wire), - generator itself, or - faulty PCM.
