U0419 code meaning
Invalid Data Received From Steering Effort Control Module
What U0419 means
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.
U0419 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0419
- Steering system warning in the cluster
- Steering ratio or assistance no longer speed-dependent
Common causes of U0419
- PossibleSteering effort module or its actuator reporting implausible values
- PossibleClock spring, connector or bus wiring fault in the steering branch
- Less likelyModule not calibrated or configured after replacement
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0419 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 19 | The exact fault in that area. |
What to do next
- Note U0419 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 U0419
What does U0419 mean?
U0419 means "Invalid Data Received From Steering Effort Control Module". U0419 concerns the steering effort control module, which varies the assistance or steering ratio the driver feels. It is a generic code, so it means the same on every make.
Is it safe to drive with U0419?
U0419 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0419 fail an emissions test?
U0419 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 U0419 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will U0419 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
