✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $100 – $1500
Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Radio/infotainment screen blank or frozen
- No sound from speakers — or sound cutting in and out
- Audio system not functioning as expected
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed audio module — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the audio/infotainment system circuit
- Blown fuse for the audio/infotainment system circuit — check before replacing components
- Faulty control module driving the audio module
- Loose or corroded ground point shared by the audio/infotainment system
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($11-117 at shop, free at auto parts store for basic scan)
- Visually inspect the audio/infotainment system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $137 diagnostic fee at shop)
- Replace audio module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($100-1500)
- Check and replace any blown fuses in the audio/infotainment system fuse circuit — if fuse blows again, there's still a short that needs to be found ($3-18 for fuses)
- Perform a wiggle test on the audio/infotainment system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-145 diagnostic labor)
