AFTER SERVICE REPLACEMENT OF SDMS WHICH CONTAIN THE INERTIAL MEASUREMENT UNIT (IMU), THE IMU SENSOR SHOULD BE RE-ZEROED. THE SDM SET UP PROCEDURE WHICH IS RUN AFTER REPLACEMENT DID NOT HAVE THE PROCESS TO RE-ZERO THE IMU SENSOR FOR THESE VEHICLES. THIS OMISSION DOES NOT IMPACT AIRBAG PERFORMANCE; HOWEVER, SOME ELECTRONIC BRAKE CONTROL MODULES (EBCM) WILL NOT ACTIVATE THE HILL HOLD ASSIST (HAS) FEATURE UNTIL THIS PROCESS IS PERFORMED.
