I'm not very familiar with diesel cars. But looks like at 0x14C1A2 CEL switches are start's. At 0x14C2D4 DTC's list start's.
Try to change some of 0x04 to 0x00 for checking.
More likely it starts at 0x14BBD4 because that data looks very similar to DTC area from already defined ROM with CAL ID JP4A130A. Someone who is familiar with diesel ROMs needed.
