What do these codes mean?

Asked by Apr 30, 2017 at 06:42 PM about the 2003 Lexus RX 300 AWD

Question type: Maintenance & Repair

The VSC light is on and I'm just wondering if that's
the source of the mysterious wobble the car makes
over 60. When we ran the diagnostics these codes
came up. Any help?
