B2004-13-REAR RIGHT AUDIO SPEAKER OUTPUT - CIRCUIT OPEN - BASE

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

NOTE: There are two versions of the B2004-13 DTC test. In order to select the proper test you must know if the vehicle is equipped with an Amplifier. If the vehicle is equipped with an Amplifier use the B2004-13-PREMIUM test. If the vehicle is not equipped with an Amplifier use the B2004-13-BASE test.

Theory of Operation

The (X304) Right Rear Speaker (+) circuit and the (X394) Right Rear Speaker (-) circuit are outputs of the Radio. The Radio controls and monitors these circuits for a concern.

For a detailed description of the Audio System. Audio And Video - Description.

For additional information regarding the operation of the Audio System. Audio And Video - Operation.

- When Monitored:
With the ignition on.

- Set Condition:
The Radio detects an open condition on the speaker output circuit.





1. CHECK FOR AN INTERMITTENT CONDITION

NOTE: A front door must remain open whenever checking or erasing Radio DTCs.

1. With the scan tool, record and erase the Radio DTCs.
2. Cycle the ignition switch from on to off, wait five seconds and then back to on.
3. Turn the Radio on and set the volume to 25.
4. Adjust the speakers to the Rear and center.
5. With the scan tool, read the active Radio DTCs.

Does the scan tool display active: B2004-13 REAR RIGHT AUDIO SPEAKER OUTPUT- CIRCUIT OPEN?

Yes

- Go To 2

No

- 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. Body Verification Test.

2. CHECK THE RIGHT REAR SPEAKER
1. Turn the ignition off.
2. Disconnect the Right Rear Speaker harness connector.
3. Measure the resistance of the speaker between the two terminals.

NOTE: The graphic shows the connector for reference only. Measure between the speaker terminals.

Is the resistance above 5.0 Ohms?

Yes

- Replace the Right Rear Speaker. Speaker - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. CHECK THE (X304) RIGHT REAR SPEAKER (+) CIRCUIT FOR AN OPEN
1. Disconnect the Radio harness connector.
2. Measure the resistance of the (X304) Right Rear Speaker (+) circuit between the Radio harness connector and the Right Rear Speaker harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 4

No

- Repair the (X304) Right Rear Speaker (+) circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. CHECK THE (X394) RIGHT REAR SPEAKER (-) CIRCUIT FOR AN OPEN
1. Measure the resistance of the (X394) Right Rear Speaker (-) circuit between the Radio harness connector and the Right Rear Speaker harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Replace the Radio. Radio - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (X394) Right Rear Speaker (-) circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
