B P1274 LEAF VCM TCU REPRO NTB12-015 PERFORM FACTORY RECALL 29034 W40 14214 REPROGRAMMED VCM & TCU AS PER CAMPAIGN
So, looking at the three campaigns that were done, I conclude that they were likely for three different VIN number ranges:
P1272/NTB12-013: Perhaps for the newest LEAFs. NTB contains 31 pages of instructions.
P1273/NTB12-014: For a group of LEAFs including mine: 5926. NTB contains 52 pages of instructions.
P1274/NTB12-015: Perhaps for older LEAFs, including surfingslovak's. NTB contains 42 pages of instructions. surfingslovak, can you confirm whether your LEAF is older or newer than mine?
I've done some more reading and sleuthing on these three campaigns and it seems clear that the campaigns are, at least partially, keyed from the VCU Part Number in the car. You can determine the current Telematics Part Number for your LEAF by following these steps:
1) Go into navigation system diagnostics (turn off radio, press Map three times, Radio Power two times, Map once).
2) Select Confirmation/Adjustment.
3) Select Version Information
4) Record the Part Number entry: XXXXX The next to last X in your VCU part number tells whether or not your LEAF has a battery heater: 0=No Battery Heater, 1=Battery Heater
So here are the VCU Part Numbers that these three campaigns were supposed to have been applied to:
P1272/NTB12-013:
Vehicle configuration ASCD: 273D0-3NA0B, 273D0-3NA0C, 273D0-3NA0D, 273D0-3NA0E
Vehicle configuration ASCD with Battery Heater: 273D0-3NA1A, 273D0-3NA1B, 273D0-3NA1C
P1273/NTB12-014:
Vehicle configuration ASCD: 273D0-3NA0B, 273D0-3NA0C, 273D0-3NA0D, 273D0-3NA0E
Vehicle configuration ALL: 283B0-3NA0A, 283B0-3NA0B, 283B0-3NA0C, 283B0-3EM0A, 283B0-3EM0B
Vehicle configuration ALL: 293A0-3NABA
P1274/NTB12-015:
Vehicle configuration ASCD: 273D0-3NA0B, 273D0-3NA0C, 273D0-3NA0D, 273D0-3NA0E
Vehicle configuration ASCD with Battery Heater: 273D0-3NA1A, 273D0-3NA1B, 273D0-3NA1C
Vehicle configuration ALL: 283B0-3NA0A, 283B0-3NA0B, 283B0-3NA0C, 283B0-3EM0A, 283B0-3EM0B
The prefixes listed seem to be:
273D0: EV/HEV
283B0: Telematics
293A0: HV Battery
So, looking at this, it appears that P1273/NTB12-014 may apply to older LEAFs without the option for a battery heater. P1272/NTB12-013 and P1274/NTB12-015 seem to apply to two later groups of LEAFs, but perhaps they are divided by VIN numbers or SL versus SV since it appears P1274/NTB12-015 gets a telematics update that P1272/NTB12-013 does not get.
Anyway, if we can confirm/correct the decoding of the VCU Part Number, this might be useful information to add to the Wiki.
