U0460 code meaning
Invalid Data Received From Automated Driving System Interface Module B
What U0460 means
Interface module B is the second, redundant link between an automated driving computer and the brakes, steering and propulsion. Bosch says plainly that automated driving is impossible without redundancy, which is why it doubles brake and steering paths. U0460 applies when B still communicates but its data are corrupt or implausible, for example out-of-sequence counters or CRC errors; if B falls silent, U015F is set, and U045F covers interface A. No manufacturer documents U0460 publicly. With only one trustworthy path left, a system above SAE level 2, where the machine rather than the driver watches the road, will usually refuse to engage or request a takeover, while a lower-level assistant may keep working with reduced functions. Software mismatches after updates, loose plugs and supply dips are the usual suspects.

Symptoms of U0460
- Automated driving unavailable or takeover request
- Assistance functions limited
Common causes of U0460
- Most likelySoftware level of interface module B not matching after an update
- PossibleLoose plug or supply dips at interface B
- Less likelyInternal fault of interface module B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0460 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 60 | The exact fault in that area. |
What to do next
- Note U0460 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 U0460
What does U0460 mean?
U0460 means "Invalid Data Received From Automated Driving System Interface Module B". Interface module B is the second, redundant link between an automated driving computer and the brakes, steering and propulsion. It is a generic code, so it means the same on every make.
Is it safe to drive with U0460?
Drive gently and only to a workshop. With U0460 the car can go into limp mode (reduced power) to protect itself.
Will U0460 fail an emissions test?
U0460 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 U0460 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will U0460 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
