B0460 code meaning
Bluetooth Antenna Circuit
What B0460 means
B0460 appears in none of the accessible J2012 lists and in no manufacturer document, so it remains unproven. Its title concerns the Bluetooth antenna circuit. GM's Global A system in the Saab 9-5 and 9-4X (2011) covers the same part under its own number B2485: the small antenna sits directly on the OnStar module without a cable, is tested once a second, and an open or grounded antenna disables Bluetooth and turns the status LED red. Visteon's US20040116084A1 sends DC down an antenna feed and judges open or short from the current drawn, while Delphi's US6999858B2 detects a removed antenna by a floating DC node or by a mismatch at the transmitter output. Poor range or lost pairing points here; a dead Bluetooth chip belongs to B0440.

Symptoms of B0460
- Phone pairs only at very short distance or not at all
- Bluetooth switched off by the module, status lamp red
- Calls and streaming break up repeatedly
Common causes of B0460
- Most likelyAntenna contact or plug at the module loose or corroded
- PossibleAntenna or its lead damaged, e.g. after work behind the dash
- Less likelyAntenna detection or radio stage inside the module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0460 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 60 | The exact fault in that area. |
What to do next
- Note B0460 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about B0460
What does B0460 mean?
B0460 means "Bluetooth Antenna Circuit". B0460 appears in none of the accessible J2012 lists and in no manufacturer document, so it remains unproven. It is a generic code, so it means the same on every make.
Is it safe to drive with B0460?
B0460 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B0460 fail an emissions test?
B0460 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B0460 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will B0460 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
