U0460 indicates that the Powertrain Control Module (PCM) has detected invalid or corrupted data from the Automated Driving System Interface Module B (ADS‑B). This communication fault prevents the vehicle’s driver‑assist functions from operating correctly.
The module itself has an internal failure or corrupted firmware, sending data that the PCM cannot interpret.
Corroded pins, broken wires, or loose connectors cause signal distortion or loss.
Insufficient voltage or a bad ground can produce spurious data that appears invalid to the PCM.
The PCM and ADS‑B Module B may have incompatible software revisions, leading to communication errors.
A malfunction in the PCM’s communication controller can misinterpret valid data as invalid; this is uncommon compared to module or wiring issues.
In most cases no. The PCM is rarely the source of this fault; the problem is usually with the ADS‑B Module B, its wiring, or power/ground supply. Replacing the PCM is a last‑resort step after all other possibilities have been ruled out.
Yes, if the issue is due to a firmware mismatch between the PCM and the ADS‑B Module B, updating one or both modules to the latest software version can clear the code.
The engine and basic drivability will remain unaffected, but any driver‑assist or autonomous functions that rely on the ADS‑B Module B will be disabled or limited.
No. U0460 pertains to the communication link with the Automated Driving System Interface, not to emissions controls or catalytic converter performance.
