The C-280 was available with or without a separate audio amplifier. If yours has the amplifier, check 25A fuse 5 in the rear fuse box which feeds power to the amplifier

I have a 1998 dodge ram I recently replaced the radio antenna and now my stereo does not work and neither do my headlights


The new antenna is not properly grounded, or the power antenna is not a powered one. The radio uses it to ground, or the radio and light circuit needs alternate ground.

What does fuse called radio-b do?


If your unit has digital display as most do now, RADIO-B will supply constant power to power the units memory so it can remember the preset channels, starting volume etc. The power antenna is usually controlled by a separate wire from the unit (normally blue) this wire supplies a low voltage signal to the antenna, The antenna will also have its own power supply and earth at the base of the antenna, the problem could be there. depending on the antenna, some have a controlling relay that is separate, again another possible source. there will also be a fuse in the main fuse box. These will all need to be checked, along with connecting a power source to the antenna to ensure the antenna does actually work.

Section 15-00: Audio Systems—Service 1999 Taurus, Sable Workshop Manual DIAGNOSIS AND TESTING Inspection and Verification NOTE: Many customers do not understand the limitations of FM reception. Refer the customer to the Owner Guide for information about the limitations of FM radio performance.

Internal diagnostic examination of the integrated control panel, rear chassis unit and audio compact disc player should be left to the authorized radio service center. However, the automotive technician should be able to analyze and isolate radio reception conditions to the proper area or component causing the condition. All radio conditions can be isolated to one of six general areas:
  • antenna system
  • integrated control unit
  • radio speaker system
  • radio noise suppression equipment
  • rear chassis unit
  • audio communications protocol network
Retrieving Diagnostic Trouble Codes (DTCs)
Using Audio System On-Board Diagnostics
The audio system has on-board diagnostic capabilities and is equipped to check for every component available in the system even if this specific vehicle is not equipped with all components. A Diagnostic Trouble Code (DTC) will be set for the missing components. These DTCs can be ignored if the vehicle is not equipped with these components. The battery must be fully charged for proper audio system operation. The ignition switch must be in the RUN or ACC position. Turn the system on, tune in a strong AM station and verify good reception. After an AM station is checked, tune in a strong FM station. The system is now ready to enter the diagnostic mode. Diagnostic Mode:
NOTE: Battery must be fully charged for proper audio system operation and self-test.

Enter Diagnostics mode by pressing SEEK DOWN button first and then pre-set button 3. Hold both buttons for five seconds. This will suspend all normal radio functions, retain the previously selected frequency and display DIAG.
  1. NOTE: To perform diagnostics, press the appropriate buttons as instructed.

    SYSTEM CONFIGURATION SELF-TEST:
    Press pre-set button 1. This will check for connection of all possible devices and log the diagnostic trouble codes for any device that does not respond. The display will flash SELF while gathering the diagnostic trouble codes, then stop flashing when complete. To exit System Configuration Self-test, press pre-set button 1 again. To retrieve diagnostic trouble codes, press the TUNE UP button. This will display the diagnostic trouble codes if any exist. Continued pressing of the TUNE UP button will display the next diagnostic trouble code. Record codes and refer to the following table. To exit the Retrieval Mode, press pre-set button 1.


    CONFIGURATION SELF-TEST CODES Code Description 0 No diagnostic trouble codes logged 1 No response from rear chassis unit 2 No response from tape deck 3 No response from bezel microprocessor 4 No response from compact disc player 5 No response from steering wheel controls 6 No response from rear seat control 7 No response from remote climate control 8 No response from navigation module 9 Read Only Memory verification failed
    Remember, system configuration will test for all possible equipment connections. Inspect the vehicle to determine actual equipment installed.
  1. Integrated control panel display test:
    To enter the integrated control panel display test, press pre-set button 5. This check will light all segments in the integrated control panel. The system will automatically exit this test after five seconds.
  1. Integrated control panel and rear chassis unit identification:
    To enter this test, press pre-set button 3. This test identifies the software level of the integrated control panel and rear chassis unit. The integrated control panel is tested first, followed by the rear chassis unit. The completed test will exit automatically. For code identification, refer to the following table. The display will have two sequences of five codes each. The first sequence is for the integrated control panel, the second sequence is for the rear chassis unit.
