NOTE: If poor sound quality is noted in the audio
system, check the Cabin Equalization curve pro-
grammed in the instrument cluster. Make sure a
base speaker system has the Base Cabin Equaliza-
tion Curve programmed to the vehicle. If the vehicle
has a premium speaker system, make sure the Pre-
mium Cabin Equalization Curve is programmed to
the vehicle
(1) If all speakers are inoperative, check the fuses
in the Power Distribution Center (PDC). If OK, go to
Step 2. If not OK, repair the shorted circuit or com-
ponent as required and replace the faulty fuse.
(2) Turn the ignition switch to the ON position.
Turn the radio receiver ON. Adjust the balance and
fader control controls to check the performance of
each individual speaker. Note the speaker locations
that are not performing correctly. Go to Step 3.
(3) Turn the radio receiver OFF. Turn the ignition
OFF. Disconnect and isolate the battery negative
cable. Remove the radio receiver. Go to Step 4.
(4) Check both the speaker feed (+) circuit and
return (-) circuit cavities for the inoperative speaker
at the radio receiver wire harness connector for con-
tinuity to ground. There should be no continuity. If
OK, go to Step 5. If not OK, repair the shorted
speaker feed (+) and/or return (-) circuits(s) to the
speaker as required.
(5) Disconnect wire harness connector at the inop-
erative speaker. Check for continuity between the
speaker feed (+) circuit cavities of the radio receiver
wire harness connector and the speaker wire harness
connector. Repeat the check between the speaker
return (-) circuit cavities of the radio receiver wire
harness connector and the speaker wire harness con-
nector. In each case, there should be continuity. If
OK, replace the faulty speaker. If not OK, repair the
open speaker feed (+) and/or return (-) circuits(s) as
required.
