“Primary Steering Valve Command Signal Duty Cycle” and “Primary Steering Valve Power Supply Output Status” should both read “Disabled or Not Installed”.
Check for any diagnostic codes. If codes are present, you will need to calibrate the steering solenoids. For calibration procedures, refer to the "Calibrate the Steering Solenoids" section within this Special Instruction. If codes are still present, review the electrical installation and verify that the procedure was done correctly.
Once the diagnostic check is completed, start the engine. Steer to the right and steer to the left to verify proper functionality. Also, wheel lean left and wheel lean right to verify proper functionality.Calibrate the Steering Solenoids
