Two clients with older Bose Lifestyle systems called this week with the error message “Bass Module Not Found”. Three things normally cause this error message, the bass module is defective, the Bose cable is disconnected, or there is no power to the bass module. To determine if your bass module is defective, confirm the bass module is properly connected to a working electrical outlet. To confirm the outlet is working, plug in a lamp or another device to the electrical outlet. If that device works, your outlet is working. Next, there is a cable that connects your Bose console to the Bose bass module. Check both ends of the cable and confirm it is securely connected to the console and Bose bass module. Depending on the system, on the back of the console, the cable should be connected to the HT or Bass speaker output. Many times, this cable becomes disconnected due to moving the console or simple cleaning. If your Bass module is properly connected to the electrical outlet and the Bose console, the bass module is probably defective. Equipment repairs are done directly by Bose and they can be reached at 888-757-9952. Please remember, this troubleshooting does not apply to the new Bose Lifestyle 600, Lifestyle 650 Home Theater systems, or Soundbar systems with wireless bass modules.
