But the P0600 is another matter, it points to failed communications between modules but does not tell us which modules, you can assume it's failed communications from the ECU to another module.

Given the lights coming on like that I'd suggest the following:
1) Replace the Crank Sensor with a Bosch part from German Auto Supply, FCP Euro, etc.
2) Replace the RCM or send it to DJ for evaluation (he will replace bad relays and reflow any suspect solder paths).
3) I'd take a REAL close look at battery post connections, and the ground from the block to chassis or maybe install one of these modifications:

I get the idea you have failing power to the ECU/Brake Controller/TCU/Instrument panel, this can be in the RCM or in the electrical (battery/alternator) system in general.
Do the CPR first and see if it makes a difference, then if no change do the RCM. Do not do them all at once otherwise you never know what caused it and you have wasted money.
