Jim,
Independence means no dependency.

So, if the internal auditor gets involved in making up for this system weakness then they could end up auditing their own work and the system weakness will persist!
The system should help people do good work without the need for audit. It rarely does but the internal auditor has to avoid making the system depend on him or her.
Systems that depend on their internal auditors are in need of improvement. Such improvement will not come if the internal auditor perpetuates this dependency.
