What U0415 means
U0415 means a module accepts frames from the ABS control module only to find their content invalid, typically wheel speeds or brake status with a wrong counter, checksum or a value flagged as unavailable. GM's Saab 9-5 list (2011) splits it into sub-types 72 (message counter) and 74 (checksum) for the electronic brake module. Ford's 2014 code list gives it both MIL and wrench lamp. The storing module varies: Ford SSM 51489 says a 2023 F-Super Duty AWD module may log U0415 in self-test when no valid ABS signal arrives in time, harmless without MIL or other codes; FCA cures U0415-00 with MIL and a Service Transmission message on the 2025 Jeep Compass 2.0 L by TCM software (21-043-25). U0121 is lost contact, U0315 a software mismatch.
U0415 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyHard
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0415
- ABS, traction or stability warning lamps
- Check engine light and Service Transmission message (model-specific)
- AWD, steering or camera functions limited
Common causes of U0415
- Most likelySoftware of the receiving module (TCM, AWD, steering) too strict or faulty; update available
- PossibleABS module passing on implausible values, for example from a faulty wheel speed sensor
- PossibleDisturbed CAN traffic from water in connectors, wiring or low voltage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0415 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 15 | The exact fault in that area. |
What to do next
- Note U0415 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 U0415
What does U0415 mean?
U0415 means "Invalid Data Received From Anti-Lock Brake System (ABS) Control Module". U0415 means a module accepts frames from the ABS control module only to find their content invalid, typically wheel speeds or brake status with a wrong counter, checksum or a value flagged as unavailable. It is a generic code, so it means the same on every make.
Is it safe to drive with U0415?
Drive gently and only to a workshop. With U0415 the car can go into limp mode (reduced power) to protect itself.
Will U0415 fail an emissions test?
U0415 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 U0415 to fix?
Difficulty: hard. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will U0415 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
