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.

The link Bass posted is Sticky'd at the top of the forum as "How To Pull Codes (DTC's)". It has the link to the definitions.

Of your four posted codes only B 0429 comes to memory - probably the rear seat HVAC console diverter actuator. I haven't memorized the others - yet.
