U05A7Invalid Data Received From Safety Integration Control Module

U05A7 indicates that a control module on the vehicle's network received invalid or corrupted data from the Safety Integration Control Module, which is the module responsible for coordinating safety systems such as airbags, seatbelt pretensioners, and crash sensors. The receiving module detected that the data frames from the Safety Integration Control Module did not match expected values or were missing required information, so it flagged the communication as invalid.
