Please ensure vehicle voltage is within specified limits. Most faults will store after an ignition cycle if the vehicle voltage is within specified limits. Check TERMINAL RETENTION ON CONNECTOR C1 PIN 11, CIRCUT D 282 CAN FD+_2 and repair any loose connection. For Loss OF Communication faults, please follow the diagnostic service routine in Service Library and confirm these steps before ORC replacement. Reference Service Library Section 28 - DTC-Based Diagnostics / MODULE, Body Control (BCM) / Diagnosis and Testing / U0151-00-LOST COMMUNICATION WITH RESTRAINTS CONTROL MODULE. The Standard Procedure / COMMUNICATION DIAGNOSTIC PROCEDURE must be performed before replacing any component(s) or module(s). AT A MINIMUM THESE PROCEEDURES MUST BE CHECKED: 1).
