Codes 51, 53 and 73

Hi there! newbie here.

I have an 07 Yaris that was in an fender bender and the driver side bag was deployed, when I got the car there where no lights the SRS light was off. I bought a used airbag ECU and Spiral cable and after a week of use the SRS light came on. I was able to read the codes by shorting 4 and 13 pin and I got these codes:

51, 53 and 73

Any help will be appreciated.

Thank you!

51: Short or open in driver side squib circuit
53: Short or open in driver side squib second step circuit
73: Short or open in driver side front pretensioner squib

The first and second indicate that you either got a bad clockspring or airbag (or did not plug in the connectors).

The third is because the seat belt needs to be replaced. There is a charge in the seatbelt coil that locks the seatbelt when the airbag deploys.
