Possible Sources

  • Wiring, terminals, or connectors
  • Audio unit antenna
  • FM 2 antenna amplifier
  • Antenna isolator module
  • Antenna cable
  • Noise suppression equipment
  • Ignition system concern
  • Generator
  • Rear window glass
  • ACM

NOTE: Prior to carrying out diagnostics, it may be beneficial to determine the cause using the Antenna Kit Tool 420-525 (Rotunda part number NUD420-525) or equivalent tool.

A1 CHECK THE AUDIO SYSTEM RECEPTION
  • Operate the audio system in radio tuner AM / FM mode.
  • Check the reception with the engine running (rear window defroster on/off) and with the engine off.

Does the poor reception only occur with the engine running?
Yes GO to A2
No GO to A6

A2 CHECK THE AUDIO SYSTEM RECEPTION WITH THE REAR WINDOW DEFROSTER ON
  • Start the engine.
  • Operate the audio system in AM / FM mode.
  • Check the reception with the rear defroster on and off.

Does the poor reception only occur with the rear window defroster on?
Yes GO to A5
No GO to A3

A3 CHECK THE GENERATOR
  • Ignition OFF.
  • Disconnect the wiring harness to the generator.
  • Start the engine.
  • Operate the audio system in AM / FM mode.

Is the reception OK?
Yes INSTALL a new generator. REFER to the appropriate Removal and Installation procedure in section 414-02.
No GO to A4

A4 CHECK THE IGNITION CIRCUITS
  • Ignition OFF.
  • Connect the wiring harness to the generator.
  • Inspect the engine compartment and make sure all ignition coils are correctly and securely connected, and no cracks are visible in the coil housings.
  • Inspect all the wiring harnesses and connectors for damaged insulation and loose or broken conditions.

Are the ignition components OK?
Yes USE a jumper cable to ground various parts of the vehicle to the frame (for example: engine, fenders, stone deflectors, and body sheet metal). When the noise is eliminated, PROVIDE a permanent ground where necessary.
No REPAIR the ignition system as necessary.

A5 CHECK THE REAR WINDOW DEFROSTER OPERATION
  • Check the operation of the rear window defroster and make sure it operates correctly.

Does the rear window defroster operate correctly?
Yes INSTALL a new radio antenna isolator module.
REFER to: Antenna Isolator Module (415-00 Information and Entertainment System - General Information, Removal and Installation).
No DIAGNOSE the rear window defroster.
REFER to: Glass, Frames and Mechanisms (501-11 Glass, Frames and Mechanisms, Diagnosis and Testing).

A6 CHECK FOR ACM (AUDIO FRONT CONTROL MODULE) ANTENNA VOLTAGE OUTPUT
  • Ignition OFF.
  • Disconnect the AM / FM 1 antenna cable from the ACM .
  • Disconnect the FM 2 antenna cable from the ACM (if equipped).
  • Ignition ON.
  • NOTE: Refer to the diagram at the beginning of this test to identify the correct cable connection to the ACM . Using the female Flex Probe 300-08058 (0.5 mm x 0.5 mm) or equivalent, measure:
    Positive Lead Measurement / Action Negative Lead
    AM / FM 1 antenna cable core at the ACM (component side)   Ground
    FM 2 antenna cable core at the ACM (component side) (if equipped)   Ground

Is the voltage greater than 11 volts?
Yes GO to A7
No GO to A11

A7 CHECK FOR VOLTAGE TO THE ANTENNA AND ANTENNA AMPLIFIER (IF EQUIPPED)

NOTE: The audio unit antenna cable is also known as the AM / FM 1 antenna cable.

  • Ignition OFF.
  • Connect the AM / FM 1 antenna cable to the ACM .
  • Connect the FM 2 antenna cable to the ACM (if equipped).
  • Disconnect the AM / FM 1 antenna cable from the audio unit antenna.
  • Disconnect the FM 2 antenna cable from the FM 2 antenna amplifier (if equipped).
  • Ignition ON.
  • Measure:

      FM 2 antenna cable from the FM 1 Antenna Cable


    Positive Lead Measurement / Action Negative Lead
    FM 2 antenna cable from the FM 1 antenna cable core, pin 1   Ground

      FM 2 Antenna Cable (if equipped)


    Positive Lead Measurement / Action Negative Lead
    FM 2 antenna cable core at the FM 2 antenna   Ground

Is the voltage greater than 11 volts?
Yes GO to A8
No IDENTIFY the antenna cable with the open or short condition. INSTALL a new cable in question.

A8 ISOLATE THE AUDIO UNIT ANTENNA
  • Install a new audio unit antenna.
    REFER to: Audio Unit Antenna (415-00 Information and Entertainment System - General Information, Removal and Installation).
  • Operate the audio system in AM / FM mode.

Is the reception OK?
Yes The system is operating correctly at this time. The concern was caused by the audio unit antenna.
No If equipped with a FM 2 antenna, GO to A9
If not equipped with a FM 2 antenna, GO to A11

A9 ISOLATE THE FM (FREQUENCY MODULATION) 2 ANTENNA AMPLIFIER
  • Install a new FM 2 antenna amplifier.
    REFER to: FM2 Diversity Antenna Amplifier (415-00 Information and Entertainment System - General Information, Removal and Installation).
  • Operate the audio system in FM mode.

Is the reception OK?

NOTE: On vehicles not equipped with the 10 speaker system, but equipped with tweeter speakers, the front door speaker and tweeter speaker share the same audio signal. If a concern exists with both speakers, retest the system with one of them disconnected to determine if the disconnected speaker is the cause of the fault.
