2005 tacoma air bag light on DTC's codes HELP!!!

Hello All, I'm hopping someone can help me with this codes.

So I read the DLC3 wiring it and this are the DTC codes I got:

35
37
51
53
73

I google those codes and I got that they are:

B1653/35: Seat position Airbag Sensor Circuit Malfuntion
B1655/37: Driver side Seat Belt Buckle Switch Circuit Malfuntion
B1800/51: Short in Driver Side Squib circuit
B1810/53: Short in Driver Side Squib 2nd Step Circuit
B1900/73: Short in Driver Side Front Pretensioner Squib Circuit

Is this correct??

Can some one explain me what all that mean, and hopefully how can I fix it?

Thanks for all
