DRAC/VSSB Module Paid Troubleshooting Service Options


From the page you'll find the product offering for UD Module's technical troubleshooting services.

Typically the most conclusive step in troubleshooting a DRAC and VSSB problem is a known-good part, like one of our remanuactured modules. In the event the module doesn't solve the issue UD Modules offers paid troubleshooting services to aide in the troubleshooting of a vehicle that is experiencing a DRAC Module VSSB Module suspected problem. The existance and offering of this paid service is a courtesy to customers to provide service shop grade assistance remotely via email. Due to the amount of experience we have with these modules we can assist in pinpointing the issue that would lead to a module being suspected as faulty. This service saves customers potentially hours in shop time because we can quickly provide procedures for testing not found in service manuals. Service only for vehicles originally equipped with a module, does not cover conversions and retrofits.
