  1. Verify the Bluetooth ® antenna is properly connected to the CIM and is not damaged.
    • If the antenna is disconnected or damaged, repair or replace as necessary.
  2. Ignition ON, verify the DTC B2485 is not set.
    • If the DTC is set, replace the Bluetooth ® antenna. Clear the DTC and cycle the ignition OFF then back ON. If the DTC resets as current, replace the CIM.
