U0452 - INVALID DATA RECEIVED FROM RESTRAINTS CONTROL MODULE

Description:  Network DTC concerns occur during module-to-module communication.
Possible Causes: 
  • Invalid data network concerns - data is transferred within the normal inter-module message, but contains known invalid data. The transmitting module logs a DTC related to the invalid data concern.
  • Missing message network concerns - missing message concerns are logged by the module upon failure to receive a message from another module within a defined retry period.
Diagnostic Aids:  Check for other powertrain control module (PCM) DTCs or PCM related symptoms. Diagnose all other PCM DTCs or PCM related symptoms first.
