Sometimes one fault will cause other modules to fault.
This is known as fault cascading.
C0049 = Brake failure - low brake fluid level
P0335 = Crankshaft Position Sensor - damaged CPS, damaged damaged circuit wires, damaged connector or damaged ECM output pins
P1030 = HO2S heater control circuit sensor 1 - blown fuse, damaged or disconnected O2 sensor, damaged or disconnected circuit wires, damaged ECM output pins
Multiple, unrelated faults usually point to a serious wiring problem...damaged wires, disconnected connector, short circuited harness, etc.

True, but those would be related faults. Brake failure along with other VSS faults like DPS or ABS faults would be an example. The brake level sensor, O2 sensor, and crankshaft sensor are not related except for wiring...not even through the ECM. Other than low voltage, it is unlikely they would appears together wexcept from coincidence or wiring problems.
I believe that the occurred faults register does show the faults in order, and that they are date/time coded in some way. I suspect a bit of the order for the cascading warnings is due to the order in which they appear in the programming....the VCM gets an ABS fault, shuts down associated functions as it is programmed to do, then shows those warnings as they are initiated, or as they are listed in the program. Just my guess.That's a big hole in the diagnostics of the Spyder and why some problems are so hard to find and fix for service techs. The other thing that is odd and I don't know how it works in BUDS but the first error code presented on the screen isn't necessarily the first error that occurred.
I think that has to do with the reaction times of each module being different.
Only 17 minutes into the shift, and its gonna be a really bad day here at work. Doubt if I'll get much time to update our story today ....... sorry folks, but as soon as I can, I will. Hope y'all have a better day than Iray:
