THX, good to know! Although both AHC & VGRS get sensory input from many of same sensors. We don't think either, that those DTC from AHC. Has anything to do with current steering issue. I was just making note, they've been current for much longer than current issue, as I showed no VGRS DTC.Probably not really relevant to the issue that you’re chasing, but I believe the 3 AHC DTC can be made to go away, by unplugging the bottom two connectors on the AHC ECU. The 4th body DTC appears to be a “rain sensor” (even less relevant to your issue).
The lack of VRGS DTC, perhaps a clue!
