NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
  1. A1 CHECK THE DRIVER SEAT CONTROL SWITCH FOR VOLTAGE 
    • Ignition OFF.
    • Depower the SRS  . Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Disconnect: Driver Seat Side Air Bag C367.
