Repower

1.   WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.

   NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

   Refer to: Health and Safety Precautions (100-00 General Information, Description and Operation).
   

1. Install BECM fuses 14 (10A) and 35 (5A) in the BCM.
   

1. Connect the battery.
   Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

   Dimension: 10.0  in ( 25.4  cm)

1. Move the driver seat to the rearmost position.
   

1. Turn the ignition from OFF to ON.
   

1. • Prove out the SRS as follows: Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the airbag warning indicator with the airbag modules installed. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. 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. This is the time required for the RCM to complete the testing of the SRS. If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults.
     

1. Using a diagnostic scan tool, clear all Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
