Radio and Antenna.
The RDS function allows the vehicle operator to choose which genre (category) of music to listen to. When the SCAN button is pressed, the ACM only stops at channels falling within the selected category. If no channel in the selected category is found, the ACM continues to scan without stopping. This can appear to be a reception issue, but it is actually due to the customer's setting.

A Loud Popping Sound Is Heard When Cycling The Ignition
Refer to Wiring Diagrams Cell 130 for schematic and connector information.
Refer to Wiring Diagrams Cell 20 for schematic and connector information.
Normal Operation and Fault Conditions
The PCM provides voltage to the ACM on the start signal circuit when the ignition is in the START position. When the voltage is received by the ACM , the audio signal output is muted to prevent voltage spikes from producing popping noises through the speakers. An open on the circuit between the splice and ACM could cause voltage spikes to produce popping noises through the speakers.

Possible Sources
Visual Inspection and Diagnostic Pre-checks
Inspect the suspect area for any possible rattle conditions such as:
D1 ISOLATE THE ZONE | ||||
Does applying pressure to a trim panel reduce or eliminate the audible noise?
|
||||
D2 REMOVE AND INSPECT BEHIND/UNDERNEATH THE SUSPECT TRIM PANEL(S) | ||||
Was the source of the noise located?
|
||||
D3 CHECK THE SUSPECT SPEAKER FOR WATER INTRUSION | ||||
Are any watermarks present on the speaker?

ACM
.
A short to ground or short to voltage in the circuitry 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 fault DTC sets.
The PCM provides voltage to the ACM on the start signal circuit when the ignition is in the START position. When the voltage is received by the ACM , the audio signal output is muted to prevent voltage spikes from producing popping noises through the speakers. A short to voltage on this circuit causes the ACM output to be muted continuously.
