B14C7
B14C7-CHANNEL 11 AUDIO SPEAKER OUTPUT CIRCUIT SHORTED TOGETHER
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 amplifier detects that the output circuits are shorted together.
Diagnostic Test
1. CHECK FOR AN INTERMITTENT CONDITION
1. Turn the ignition on and open one of the front doors.
NOTE: A front door must remain open whenever checking or erasing Amplifier DTCs.
2. With 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 20.
5. Adjust the speakers to the front and center.
6. With the scan tool, read the active Amplifier DTCs.
Does the scan tool display active: B14C7-CHANNEL 11 AUDIO SPEAKER OUTPUT CIRCUIT SHORTED TOGETHER?
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 OPERATION OF THE AMPLIFIED RIGHT REAR TWEETER SPEAKER
1. Turn the ignition off.
2. Disconnect the Amplifier C2 harness connector.
3. Disconnect the Amplified Right Rear Tweeter speaker harness connector.
4. Measure the resistance of the Amplified Right Rear Tweeter speaker between the component terminals.
Is the resistance of the speaker less than 1 Ohm?
Yes
- Replace the Amplified Right Rear Tweeter Speaker.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 3
3. CHECK THE (X212) AMPLIFIED RIGHT REAR TWEETER SPEAKER (+) CIRCUIT, AND THE (X282) AMPLIFIED RIGHT REAR TWEETER SPEAKER (-) CIRCUITS FOR A SHORT TOGETHER
1. Measure the resistance between the (X212) Amplified Right Rear Tweeter Speaker (+) circuit, and the (X282) Amplified Right Rear Tweeter Speaker (-) circuit.
Is the resistance below 10K Ohms?
Yes
- Repair the (X212) Amplified Right Rear Tweeter Speaker (+) circuit, and the (X282) Amplified Right Rear Tweeter Speaker (-) circuit for a short together.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Replace the Amplifier.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
