BUNCH of codes after dealer rattle "fix"
 

This past week the dealership did their fix for the rattle...of course didnt work but that's a different conversation. I put in the raptor grill light and plugged in forscan to have that on always and immediately get a ton of codes. 99% relating to ABS. Example: P0557, P1935, U0121, U0415, U1012

Code: P0557 - Brake Booster Pressure Sensor Circuit Low

Status:
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC
- Test not complete

Module: Powertrain Control Module

===END PCM DTC P0557:00-68===

===PCM DTC P1935:00-68===
Code: P1935 - Brake Switch/Sensor Signal

Status:
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC
- Test not complete

Module: Powertrain Control Module

===END PCM DTC P1935:00-68===

===PCM DTC U0121:00-68===
Code: U0121 - Lost Communication With Anti-Lock Brake System (ABS) Control Module A


They repeat for 80% of the modules, same codes.

Then some random ones, U0253, U0417, C2008, C101a, C003a...the last one being for right rear wheel speed sensor and a code popped for every tire.

Did the dealership screw something up putting it back together or is it because they tore everything apart and forscan is just being weird? Any insight would be appreciated!!

They probably had the key on with the wires disconnected which is why it says previously set not present at this time. It's just the history.

Just clear the codes via Forscan and see if they come back.
