U0460 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. 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.

Likely causes

Software level of interface module B not matching after an update
Loose plug or supply dips at interface B
Internal fault of interface module B

Symptoms

  • Automated driving unavailable or takeover request
  • Assistance functions limited
