    P0600 is a Serial Communication Link Malfunction. Since the battery reset didn't solve the problem, it may be a wiring problem, a short, disconnected wire, that sort of issue. You're probably going to need the help of an auto tech who has the diagnostic tools needed to see what's going on.

    This code can set from low ignition switch voltage. Test for a voltage drop to PCM pins:
    Pin 5, C1 pink. Engine fuse 15 (20 amp)
    PIN 2 , C2 pink. Comes from IGN fuse 10 (20 amp)

    If the ignition switch is failing you will find lower than system voltage on those fuses during one of the events. (Simply leave the key on, and measure the battery voltage, then move just the positive lead of the voltmeter to these fuses and compare the readings to the battery voltage)

    BTW. That would also mean that the information of disconnecting the battery and getting the car to start is misleading.
