U0422Invalid Data Received From Body Control Module

- How the car detects it
- U0422 applies to cars with a single body controller; with several, U0431 names body control module A and U0443 to U0446 modules B to E. A receiver logs it when BCM frames arrive but carry unusable content. GM's 2025 ECM checks body information frames with 8 faults in 18 samples and serial data frames with 3 in 10, after 5 s at 11 V or more, as Type B, so the MIL follows a second faulty trip. Ford's 2012 OBD guide has the PCM set U0422 without MIL when VIN, tire, axle or vehicle configuration data from the BCM lie outside their valid range, or when the engine-off timer reads FFFFh after a battery disconnect. Volkswagen's 2014 Touareg book uses it for an ambient temperature of 00h. FCA links an active U0422 in the hybrid processor of the 2021 Pacifica to a check engine light. U0140 is lost contact.
