what to when my indicator said drive box fault

THERE IS NO WAY TO DETERMINE THE PROBLEM WITHOUT USING A SCANNER TO CHECK CODES AND DATA. THE DIAGNOSTIC FEE WOULD BE $85.00 TO DETERMINE THE PROBLEM. WE HAVE THE FACTORY SCANNER AND ALL FACTORY SERVICE MANUALS TO PERFORM THIS SERVICE, SHOULD YOU BE INTERESTED. PLEASE CALL TO SET UP AN APPT. OR YOU CAN DO SO AT www.flowerhillauto.com.
