I'm not 100% up to snub on what all the order codes are, but I believe this is them:

BB - review by fleet department
BD - special equipment processing
BE - edit error
BG - passed edit n/a for schedule
BGL - edit ok parts unavailable
BX - passed edit available for schedule
C - sub firm
D - firm schedule - dealer has allocation and all parts available
D1 - gateline schedule - scheduled to be built
E - frame
F - paint
G - trim
I - built not ok'd
J - built ok'd
JB - shipped to body vendor
JE - emission check
JS - shipped to storage
KZ - released by plant , invoiced
KZL - released - not shipped
KZM - first rail departure
KZN - first rail arrival
KZO - delayed/recieved
KZOA - plant holds
KZOB - zone/distribution holds
KZOC - carrier delays
KZOD - carrier holds
KZOE - mis-shipped vehicle
KZOF - show/test vehicle
KZOG - damaged vehicle
KZOH - all other reasons
KZT - second rail departure
KZU - second rail arrival
KZX - delivered to dealer
ZA - canceled


"C" status would mean your car has not been allocated and does not have a firm production date.
