 |
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
The (X202) Right Front Speaker (+) circuit and the (X292) Right Front Speaker (-) circuit are outputs of the Radio. The Radio controls and monitors these circuits for a concern.
-
When Monitored:
With the Radio on.
-
Set Condition:
The Radio detects a short to battery condition on the speaker output circuit.
Possible Causes |
|---|
| (X202) RIGHT FRONT SPEAKER (+) SHORTED TO VOLTAGE |
| (X292) RIGHT FRONT SPEAKER (-) SHORTED TO VOLTAGE |

1. CHECK FOR AN INTERMITTENT CONDITION
| NOTE: | This vehicle has a Front Tweeter wired in parallel with the Front Speaker. |
| 1. | Turn the ignition on and open one of the front doors. |
| NOTE: | A front door must remain open whenever checking or erasing Radio DTCs. |
| 2. | Using the scan tool, record and erase the Radio DTCs. |
| 3. | Turn the Radio on. |
| 4. | Adjust the speakers to the front and center. |
| 5. | Using the scan tool, read the active Radio DTCs. |
Does the scan tool read: B1406-FRONT RIGHT AUDIO SPEAKER OUTPUT CIRCUIT HIGH?
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. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
2. CHECK FOR VOLTAGE ON THE (X202) RIGHT FRONT DOOR SPEAKER (+) CIRCUIT
 |
| 1. | Turn the ignition off. |
| 2. | Disconnect the Radio C2 harness connector. |
| 3. | Turn the ignition on. |
| 4. | Measure the voltage between the (X202) Right Front Door Speaker (+) circuit. |
Is there any voltage present?
Yes
- Repair the (X202) Right Front Door Speaker (+) circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
No

3. CHECK FOR VOLTAGE ON THE (X292) RIGHT FRONT DOOR SPEAKER (-) CIRCUIT
 |
| 1. | Measure the voltage between the (X292) Right Front Door Speaker (-) circuit. |
Is there any voltage present?
Yes
- Repair the (X292) Right Front Door Speaker (-) circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
No
