U0415 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. 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.

Likely causes

Software of the receiving module (TCM, AWD, steering) too strict or faulty; update available
ABS module passing on implausible values, for example from a faulty wheel speed sensor
Disturbed CAN traffic from water in connectors, wiring or low voltage

Symptoms

  • ABS, traction or stability warning lamps
  • Check engine light and Service Transmission message (model-specific)
  • AWD, steering or camera functions limited
