CHAPTER 8
68 RCM - Sprayer and AIM Command FLEX™ II Calibration and Operation Manual
The following trouble codes may be displayed by the control system and should help the operator to identify and
correct issues with system during field operations:
NOTE: Before taking any of the following Recommended Actions, it is suggested to check for any available
software updates for components on the system, cycle machine power, reboot the controller, edit/
create a machine profile, recalibrate the system, or check all wiring for damage, as these are common
remedies and can potentially solve several issues. If none of the following Recommended Actions
solve the issue(s), it is recommended to replace the RCM-S ECU or NCV(s) affected.
Code ID Description Recommended Actions

.13 Yaw sensor calibration error • Park machine on level ground and disable any
boom height controls. Go to Tools -> System
Settings -> User Settings -> Calibrate Turn
Compensation and verify the detected
orientation is accurate, and ensure Yaw Rate is
not varying by +/-.5 deg/sec while the engine
is running. If needed, select Redetect
Orientation to recalibrate.
• Cycle power to RCM-S ECU by going to
Diagnostics -> Tests -> Reboot Product
Controller.
