Pinpoint Tests

Poor AM/FM Reception or Continuous Seek/Scan


For wiring diagrams and connector information, refer to Cell 130 of the Wiring Diagrams.


For circuit and connector information, refer to Section 12 Wiring Diagrams.

Normal Operation and Fault Symptoms


REFER to: Information and Entertainment System - System Operation and Component Description (Information and Entertainment System 415-00A - General Information - vehicles with: AM/FM/CD/SYNC, Description and Operation).

The RDS function allows the vehicle operator to select a music genre (category) to listen to. When the SCAN button is pressed, the ACM only stops on stations that fall within the selected category. If no station in the selected category is found, the ACM continues to scan without stopping. This may appear to be a reception concern, but it is related to the audio system settings.

Possible Sources

  • No Station Found in Selected Category
  • Charging System
  • Wiring, Terminals or Connectors
  • Ignition System
  • Noise Suppression Device
  • AM/FM Antenna Coaxial Cable
  • AM/FM Antenna
  • Corrosion at Mounting Surface

A short to ground or a short to voltage in the circuit to one of the speakers may cause multiple speakers to lose sound due to the built-in overload protection feature of the ACM. In this case, a speaker DTC is set.

The PCM supplies voltage to the ACM on the start signal circuit when the ignition is in the START position. When voltage is supplied to the ACM, the audio output is muted to prevent pops from being heard through the speakers. A short to voltage in this circuit causes a constant mute of the ACM output.
