1. Repower the SRS . For a new RCM , do not prove out the SRS at this time.
   Refer to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures).
   

1. NOTE: This step is only necessary when installing a new RCM .

   Using a diagnostic scan tool, complete the PMI process for the RCM following the on-screen instructions.
   

1. NOTE: This step is only necessary when installing a new RCM .

   Carry out the ABS Calibration service function using the diagnostic scan tool and following the on-screen instructions.
   

1. For a new RCM , prove out the SRS . Verify all airbags are installed and connected and the ignition is OFF. Wait 10 seconds then turn the ignition ON and monitor the airbag warning indicator. The airbag warning indicator illuminates continuously for approximately 6 seconds and turns off. Continue to monitor the airbag warning indicator for approximately 30 seconds, as this is the time required for the RCM to complete testing of the SRS .
   
   • If a SRS fault is present, the airbag warning indicator either fails to light, remains lit continuously or flashes. The flashing may not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. If this occurs, diagnose and repair any SRS faults before proceeding with other repairs.
     
   • If, after the ignition has been turned on for 30 seconds, the airbag warning indicator remains unlit with no chime or SRS message displayed in the message center, no SRS fault is present.
     
   • If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps or a message displays in the message center. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults before proceeding with other repairs.
