Service
When replacing the dynamic steering control units (J792), online coding and parameterization must first be attempted using an SVM spec/actual comparison. If the SVM spec/actual returns a response of "Check Hardware", then it is possible one of the SVM codes listed above is required to code and parameterize the new replacement control unit.
Tip: The SVM Exchange Code (XCHG1BA001) may be required.
