Whats up guys. i have a little problems with my Scion tC. well let me start telling you what happened. i got a Scion tC crashed from the passager side but the front part ( so by the ABS side) and i fixed it up. it runs and everything but the problem is that my brake light came out, my abs and check engine. my speedometer doesnt work and cruse control i scanned i with my tool and the Code P0500 came up so i was thinking maybe my wheel speed senser is messed up so i changed only the passenger side but my speedometer still doesnt work, so i try to scan my ABS with my tool but it said there was a error reading it and i think it maybe the abs pump wire harness is messed up because in the crash that part is broken so i just pluged it back in and my car brakes and everything so i just want to make sure if its the wire thats the problem so i can just change it my self or what is the problem. thank you in advance guys. i want to finish fixing up my car so i can not be stressed out in trying to make it pass the smog. p.s the speedometer goes up and down when i turn it on.

 

Sounds like vehicle speed sensor for speedo. and check front ABS sensors if dirty, cracked or pinched wires
