Audio Amplifier - Circuit Short to Ground
This code indicates a short to ground in the audio amplifier circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
There's a wiring issue in the audio system, causing it to not work properly because the circuit is shorted to the ground, which means the electrical current can't flow as it should.
What the computer is actually seeing
The vehicle's computer detects lower than normal resistance in the audio amplifier circuit due to a short circuit, typically reading below 1 ohm where it should be in the range of several ohms.
What a healthy reading looks like
Expected resistance in the audio amplifier circuit should be between 2-10 ohms under normal conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the audio amplifier circuit wiring for any visible damage or fraying. If there is damage, repair it and retest.
- 22. Check audio amplifier connectors for corrosion, looseness, or moisture. Clean or secure as needed, then retest.
- 33. Measure the resistance of the audio amplifier circuit. It should be 2-10 ohms. If it's below 1 ohm, locate and fix the short to ground. If normal, replace the audio amplifier.
Common causes
- Frayed or damaged wiring
- Moisture or corrosion in connectors
- Faulty audio amplifier unit
Typical repair cost
$$

Frequently asked questions
Is it safe to drive with this code?
Yes, it is drivable, but you will have no audio functionality until the issue is resolved.
Will this code come back after I clear it?
If the underlying issue is not fixed, the code will likely return.
Why do I keep seeing this code along with B2315?
Both codes relate to the audio amplifier circuit; they can indicate different issues within the same audio system.
