The Audio Module is Not Receiving Proper Power Supply.

  • Check at the input terminals of the module with a multimeter to ensure that the voltage is correct and stable.
  • The correct voltage range for the audio module is 8V DC to 18V DC.

Audio Module Not Restarted Correctly.

  • If a brief power interruption has occurred, it may cause the module to not restart properly. Disconnect the module’s power supply and reconnect it.

CAN Wiring.

  • Ensure there are no cuts or deformations in the two CAN communication wires with the GSR.
  • Check that the wires are connected to the correct pins (H with H and L with L).
  • Verify that the terminals and connectors have good contact, with no sunk screws, broken strips, or loose wires.
  • Use a multimeter to check continuity in the CAN communication wires.
  • If there are multiple sections in the CAN communication installation, they should be tested independently.
