Customer Parameter Lockout
The customer parameter lockout is available in order to restrict access to changing some of the available parameters. Locking out a parameter requires customer passwords (if used). Once a parameter is locked out, factory passwords are required to change the parameter. Also, once a parameter is locked out, factory passwords are required to unlock the parameter.If a lockable parameter is not locked out, factory passwords are not required. A locked out parameter restricts the parameter from being changed directly by the customer. This helps vehicle owners that are encountering problems with operators that are obtaining customer passwords and altering some of these parameters.A locked out parameter also provides an audit trail. The audit trail can be used to determine the following information:
