PID/Data Monitor Table [DSC HU/Cm]

NOTE:
  • If the PID "STR_ANG_R" is inspected, perform the following procedure before inspecting.
  1. Switch the ignition to OFF, and maintain this condition for approx. 3 s.
  2. Set the vehicle wheels in the straight-ahead position.
  3. Switch the ignition ON (engine off or on).
