Yes, I too cannot help but wonder what all these letters/codes mean?
Found this helpful on JL Forum to aid in all the different codes.
Search nerubi on that forum for more insight..great detail from him.
Your order will usually be given a D status. See the list of build status sheet. This is the beginning status and means they are assuring parts are available and put into a general schedule. Don't get excited, you may be in this stage for days or weeks. Read the attached document about the Toledo North Assembly Plant Supply Chain process. It is a few years old but gives a very good description of the vendors involved and everything involved getting parts ready and how the build starts out.
See a listing of the main status codes below:
Unscheduled:
BX = good order available for scheduling
BB = fleet order only ñ review by bid department
BD = special equipment processing
BE = edit error - coding error which must be corrected before order can be scheduled
BG = order has passes edit but cannot be scheduled regardless of sold status
Reason Codes:
F = finance hold - automatic cancellation after 15 days
B = model or option build out
L = material restriction
M = material hold (fleet)
ZA = canceled order
Scheduled:
C = tentative schedule
D = firm schedule: serial number assigned
D1 = gateline: unit sequenced for production, est ship date assigned
Build:
E = framing
F = paint
G = trim
Built:
I = unit built, pending final inspection
J = vehicle passed final inspection but not released to carrier
JB = shipped to body vendor
JE = shipped to emissions
JJ = consigned to body vendor
JS = shipped to storage
KZ = released by plant and invoiced
Traffic Codes:
KZ L = released but not shipped
KZ M = first rail departure
KZ N = first rail arrival
KZ O = delayed/received
KZ OA = plant hold, quality audit
KZ OB = zone, dealer, sales, vehicle prep, tax, diversion or derailment hold, dealer refusal, vehicle diverted
KZ OC = carrier delay, strike-bound, emission or safety hold, rail car shortage, bad or insufficient load, inclement weather, need shipping order, manifest error
KZ OD = mechanical failure, glass damage, vehicle in repair, lacking parts or storage hold
KZ OE = misdropped or misshipped vehicle
KZ OF = shipped air freight, stolen vehicle recovered, show vehicle, test info code, vessel sailed
KZ OG = damaged vehicle, stolen vehicle, abandon to carrier, vehicle scrapped, donate vehicle, repair and auction
KZ OH = all other type carrier codes
kZ R = vehicle within a few days of dealer
KZ T = second rail departure
KZ U = second rail arrival
KZ X = delivered to dealer
KZ Y1 = major damage ñ must not be sold as new
KZ Y2 = major damage ñ vehicle sold at auction
The next status is usually D1 which means it is at the ìgatelineî to be sequenced for production. This doesn't mean it is ready to build. Notices are sent to vendors that your order will be assembled and what is needed for the build. This could take several days to a couple of weeks. You can move back to D status for various reasons. This is called D1-to-D Regress. It means you are pulled out of the build sequence. This often happens for a status L, material hold. An example is when manual transmissions were recalled and the parts required to fix it were not available so all manual transmissions orders went back to D - L.
