U0153Lost Communication With Side Restraints Control Module Right

U0153 means the vehicle's main body computer has lost the controller area network (CAN) communication link with the right-side restraints control module, the unit that fires the right-side airbags and seatbelt pretensioners. The computer detects this when it stops receiving the periodic status messages the module is supposed to broadcast, so it flags the circuit as offline rather than reporting a crash sensor fault.
