My power steering went out

I was in a hit and run accident the other day and my car was hit on the driver side door/fender. I drove my car back to my friends house to drop him off as soon as he got out of the passenger seat the airbag light for his side came on on my dashboard and my heat went out instantly. As I was driving my car the next morning my power steering went out and my blinkers no longer work. I connected the computer device to my car to see what code came up and I got the P0705. My dad wiped the codes from my dashboard twice. I set my key in the ignition to ACC for 10 minutes. Power steering came back but shut off immediately right after and then check engine light, traction control and my airbag light came back on. Do I have to replace just the TCM or the ECM?? Or both?

Answer this question I have this problem too

@kelcijoe since your vehicle was in an accident and you got a "P0705...Power steering came back but shut off immediately right after and then check engine light, traction control and my airbag light..." I would be hesitant to just replace any one of those modules., Make sure that there is no damage to your Scion that could actually cause this. Because even a new ECU/ECM might just do the same. So, if it is a module I would change the ECM. According to the wiring diagram it should not be the TCM that controls the "things" that are going haywire :-)
