B1463-CHANNEL 1 AUDIO SPEAKER OUTPUT CIRCUIT OPEN

For a complete wiring diagram, refer to the Wiring Information.

When Monitored:
Amplifier bus wake-up.

Amplifier reset with scan tool.
Set Condition:
The Amplifier detects an open condition on the speaker output circuit.

Possible Causes
(X209) LEFT INSTRUMENT PANEL (I/P) SPEAKER (+) CIRCUIT OPEN
(X299) LEFT INSTRUMENT PANEL (I/P) SPEAKER (-) CIRCUIT OPEN
LEFT INSTRUMENT PANEL (I/P) SPEAKER
AMPLIFIER

1. CHECK FOR AN INTERMITTENT CONDITION

1.	Turn the ignition on.

2.	Using the scan tool, record and erase the Amplifier DTCs.

3.	Cycle the ignition switch from on to off, wait five seconds and then back to on.

4.	Turn the Radio on and set the volume to 25.

5.	Adjust the speakers to the front and center.

6.	Using the scan tool, read the active Amplifier DTCs.

Does the scan tool display active: B1463-CHANNEL 1 AUDIO SPEAKER OUTPUT CIRCUIT OPEN?

Yes

Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

2. CHECK THE OPERATION OF THE LEFT I/P SPEAKER

1.	Turn the ignition off.

2.	Disconnect the Left I/P Speaker harness connector.

3.	Turn the ignition on.

4.	Turn the Radio on and turn the volume to 25.

5.	Adjust the speakers to the front and center.

6.	With a Voltmeter set to read in A/C voltage, measure the voltage of the Left I/P Speaker circuits in the Left Front I/P Speaker harness connector.

Is the voltage present greater than 1 Volt?

Yes

Replace the Left I/P Speaker in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

3. CHECK THE (X209) LEFT I/P SPEAKER (+) CIRCUIT FOR AN OPEN

1.	Turn the ignition off.

2.	Disconnect the Amplifier C1 harness connector.

3.	Measure the resistance of the (X209) Left I/P Speaker (+) circuit between the Amplifier C1 harness connector and the Left I/P Speaker harness connector.

Is the resistance below 2.0 Ohms?

Yes

4. CHECK THE (X299) LEFT I/P SPEAKER (-) CIRCUIT FOR AN OPEN

1.	Measure the resistance of the (X299) Left I/P Speaker (-) circuit between the Amplifier C1 harness connector and the Left I/P Speaker harness connector.

Is the resistance below 2.0 Ohms?

Yes

Replace the Amplifier in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
