Diagnostic Test
1.
CHECK FOR AN INTERMITTENT CONDITION
Turn the ignition on.
Turn the radio on.
With the scan tool, erase Amplifier DTCs.
With the scan tool, reset the amplifier.
With the scan tool, read Amplifier DTCs.
Does the scan tool display active: B1463-CHANNEL 1 AUDIO SPEAKER OUTPUT CIRCUIT OPEN?
Yes
>> Go To 2
No
>> The conditions that caused this code to set are not present at this time. Using the wiring diagram/sche-
matic as a guide, inspect the wiring and connectors.
Perform BODY VERIFICATION TEST VER-1.
2.
CHECK THE OPERATION OF THE LEFT FRONT I/P SPEAKER
Disconnect the Left I/P Speaker harness connector.
Turn the radio on and turn the volume to mid level.
With a voltmeter set to read in A/C voltage, measure the voltage of the
Amplified Left I/P Speaker circuits in the Amplified Left I/P Speaker har-
ness connector.
Is the voltage present greater than 1 volt?
Yes
>> Replace the Amplified Left I/P Speaker in accordance with
the service information.

cuit between the Amplifier C1 harness connector and the Amplified Left
I/P Speaker harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 4
No
>> Repair the (X209) Amplified Left I/P Speaker (+) circuit for
an open.
Perform BODY VERIFICATION TEST VER-1.
4.
CHECK THE (X299) AMPLIFIED LEFT I/P SPEAKER (-) CIRCUIT FOR AN OPEN

cuit between the Amplifier C1 harness connector and the Amplified Left
I/P Speaker harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Replace the Amplifier in accordance with the service infor-
mation.
