2000 S70 Multiple Error Codes

[ThreeEleven]

hey,
So im fairly new to fixing cars so im looking for some advice. I recently bought a 2000 Volvo S70 and I bought it knowing the check engine light was on and I would need to do some work on it. So when I got it I checked the engine codes and it read back P0722 , P0717 , P0733 , P0600 , P1618 P1618pd . Also the speedometer mostly doesn't work, the abs, brake, and traction control light come usually come on after diving for a bit. So once I got the codes I erased them reset the computer(I did the driving cycle for readiness) to make sure there wasnt any false codes. Also once I got the car I realized the engine wasn't grounded and after re grounding it the P0600 code was gone and I havent seen it again. So anyway now there is P0722 , P0717 , P1618 , P1618pd from what ive read online it seems to be the ABS module but id like to hear someone elses opinion on it. Also I don't know what the P1618pd code is, my diagnostics computer described it as ,No DTC found, but that is also what it says for P1618 so im confused what the pd means?

Bad ABS module can screw up may things.
Start with re-soldering the ABS module.

Does this have anything to do with me losing the S70 this post was about?
