Visual Inspection and Pre-checks

  • Inspect the glass antenna grid for damage.
A1 CHECK AUDIO SYSTEM RECEPTION WITH REAR WINDOW DEFROST ON
  • Ignition OFF.
  • Operate the audio system in AM/FM mode.
  • Monitor radio reception.
  • NOTE: Non-hybrid vehicles require the engine to be running to turn on the rear window defrost. Hybrid vehicles require the vehicle to be in Ready-to-Drive mode. Turn on the rear window defrost function and monitor radio reception.

Is poor reception present only when the rear window defrost is on?
Yes For non-hybrid vehicles, GO to A2
For hybrid vehicles, GO to A3
No GO to A6
A2 CHECK AUDIO SYSTEM RECEPTION WITH ENGINE RUNNING AND REAR WINDOW DEFROST OFF
  • Start the engine.
  • NOTE: Make sure the rear window defrost function is turned off. Do not activate it. Operate the audio system in AM/FM mode.

Is poor reception present when the rear window defrost is off?
Yes GO to A4
No GO to A3
A3 CHECK REAR WINDOW DEFROST GRID FOR PROPER OPERATION
  • Check the operation of the rear window defrost grid. Make sure all grid lines operate correctly.

Does the rear window defrost grid operate correctly?
Yes INSTALL a new noise suppression device on the rear window defrost grid connection.
REFER TO: Antenna Isolator Module (415-00 Information and Entertainment System - General Information, Removal and Installation).
No
REFER TO: Glass, Frame and Mechanisms - Vehicles With: One-Touch Up and Down Front Windows (501-11 Glass, Frame and Mechanisms, Diagnosis and Testing).
REFER TO: Glass, Frame and Mechanisms - Vehicles With: One-Touch Down Driver Window (501-11 Glass, Frame and Mechanisms, Diagnosis and Testing).
A4 CHECK THE GENERATOR
  • Ignition OFF.
  • Disconnect the generator "B" connector.
  • NOTE: Do not increase engine speed above idle speed. Start the engine.
  • NOTE: Do not increase engine speed above idle speed. Incorrect test results may be obtained if engine speed exceeds idle. Only with the engine running at idle, turn on the audio system in AM/FM mode.

Is reception normal?
Yes INSTALL a new generator. REFER TO the appropriate removal and installation procedure in Section 414-02.
No GO to A5
A5 CHECK THE IGNITION CIRCUITS
  • Ignition OFF.
  • Connect the generator "A" connector.
  • Inspect the engine compartment and make sure that all ignition coils are correctly and securely connected. Check the coil housings for cracks.
  • Inspect all wiring harnesses and connectors for damaged insulation, loose retainers or breaks.

Are the ignition components normal?
Yes USE a jumper cable to ground the various parts of the vehicle to the frame (for example: engine, fenders, side panels, rock deflectors, air cleaner and body sheet metal). When the noise is eliminated, PROVIDE a permanent ground where necessary.
No REPAIR the ignition system as necessary.
A6 CHECK THE WINDSHIELD ANTENNA GRID
  • Ignition OFF.
  • Inspect the connection to the antenna amplifier and the glass antenna grid for damage.

Is the connection to the antenna amplifier good, and the glass antenna grid undamaged?
Yes GO to A7
No REPAIR the connection to the antenna amplifier or the glass grid as necessary.
A7 CHECK THE ACM (AUDIO SYSTEM FRONT MODULE) ANTENNA VOLTAGE OUTPUT
  • Ignition OFF.
  • Disconnect the AM/FM 1 antenna cable from the ACM.
  • The ignition is on.
  • NOTE: Refer to the schematic at the beginning of this test to identify the correct cable connection to the ACM. Using flexible probe 300-08058 (0.5 mm x 0.5 mm) or equivalent, measure:

    AM / FM 1 Antenna Cable


    Positive lead Measurement/Action Negative lead
    AM/FM 1 antenna cable wire at the ACM (component side) Ground

Is the voltage greater than 11 volts?
Yes GO to A8
No GO to A10
A8 CHECK THE VOLTAGE AT THE ANTENNA AMPLIFIERS
  • Ignition OFF.
  • Connect the AM/FM 1 antenna cable to the ACM.
  • Disconnect the antenna cable from the AM/FM 1 antenna amplifier.
  • The ignition is on.
  • Action:

    AM / FM 1 Antenna Cable


    Positive lead Measurement/Action Negative lead
    antenna cable wire at the AM/FM 1 antenna amplifier Ground

Is the voltage greater than 11 volts?
Yes GO to A9
No IDENTIFY the antenna cable with an open or short circuit. INSTALL a new cable.
REFER TO: Audio Unit Antenna Cable (415-00 Information and Entertainment System - General Information, Removal and Installation).
A9 AM (AMPLITUDE MODULATION) / FM (FREQUENCY MODULATION) 1 ANTENNA AMPLIFIER ISOLATION
  • Ignition OFF.
  • Connect the antenna cable to the FM 2 diversity antenna amplifier (if equipped).
  • Install a new AM/FM 1 antenna amplifier.
    REFER TO: AM/FM 1 Antenna Amplifier (415-00 Information and Entertainment System - General Information, Removal and Installation).
  • Operate the audio system in AM/FM mode.

Is reception normal?
Yes The system operates correctly. The antenna amplifier was the concern.
No GO to A10
A10 CHECK THE ACM (AUDIO SYSTEM FRONT MODULE) OPERATION
  • Ignition OFF.
  • Disconnect and inspect all ACM connectors.
  • Repair:
    • Corrosion (clean the module terminals or install new connectors or terminals)
    • Damaged or bent terminals (install new terminals or pins)
    • Backed-out pins (install new pins as necessary)
  • Connect the ACM connectors. Make sure they are fully seated and locked.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
