Im trying to figure out a P0603 error (KAM) on my daughters 2010 xc70 3.2. Not entirely sure how the ECM is wired internally, I’m trying to eliminate all external possibilities before replacing the ECM. Could anyone tell me the pins for the KAM positive to battery? I do have have the wiring diagram, but cannot seem to figure dentify the pin. Also, which pin would be to ground? A y other thoughts?
any help is much appreciated!
