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

- When Monitored:
With the ignition on. Radio volume at 25 or higher.

- Set Condition:
The Radio detects that the output circuits are shorted together.





1. CHECK FOR AN INTERMITTENT CONDITION
1. Turn the ignition on, then off, and then on again.
2. With the scan tool, erase Radio DTCs.
3. Turn the radio on.
4. Turn the volume level to 25.
5. With the scan tool, read Radio DTCs.

Does the scan tool display active: B145D-FRONT RIGHT AUDIO SPEAKER OUTPUT CIRCUIT SHORTED TOGETHER?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE OPERATION OF THE AMPLIFIED RIGHT FRONT DOOR SPEAKER




1. Disconnect the Amplified Right Front Door Speaker.
2. Measure the resistance of the speaker between the two terminals.

Is the resistance of the speaker less than 1 Ohm?
