U0419 concerns the steering effort control module, which varies the assistance or steering ratio the driver feels. Ford uses that name for the controller of its adaptive steering: bulletin 16-2066 on the 2016 Edge and MKX stores C1B00 in the steering effort control module (SECM) and replaces the steering wheel that houses the actuator. A receiver, such as the ABS or power steering unit, logs U0419 when SECM frames keep arriving but carry implausible values, a bad counter or checksum. No manufacturer documents U0419 publicly, so thresholds and the reacting module are not known. The power steering control module has its own code, U0420. U0130 is lost contact, U0319 software. Expect a steering warning and a fixed ratio or assistance; no MIL is expected.

Likely causes

Steering effort module or its actuator reporting implausible values

Clock spring, connector or bus wiring fault in the steering branch

Module not calibrated or configured after replacement

Symptoms

Steering system warning in the cluster
Steering ratio or assistance no longer speed-dependent
