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 splice S212 and the ACM could cause voltage spikes to produce popping noises through the speakers.

No Sound From All Speakers

Refer to Wiring Diagrams Cell 130 for schematic and connector information.

Normal Operation and Fault Conditions

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