I have these four codes constantly reappearing in my DTC's.

AMP U1000
IPM B0429
PCM P0621
SDM B0082 (I believe that this is an airbag module under the seat but I haven't a clue as to what it looks like or how to fix it)

All are current codes. Just wondering what they mean and how to fix them. Thanks in advance.
