SERVICE PRECAUTIONS
 
 
warningBattery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS AFTER HANDLING.
warning
  • Carefully read observe the information in the SRS SERVICE PRECAUTIONS prior to any service.
  • For information concerning diagnosis or maintenance, always observe the procedures in the SRS diagnosis or the SRS maintenance sections, respectively.
  • If any SRS components are removed or replaced in connection with any service procedures, be sure to follow the procedures in the INDIVIDUAL COMPONENT SERVICE section for the comportments involved.
  • If you have any questions about the SRS, please contact the MMNA Tech Line.
  • Certain components of this vehicle, such as air bag modules and seat belt pre-tensioners, may contain perchlorate materials. Before deployment and/or disposal of these components, review and comply with all applicable Federal, state and local regulations.
 
 
danger
  • In order to avoid injury to yourself or others from accidental deployment of the air bag during servicing, read and carefully follow all the precautions and procedures described in this manual.
  • Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized MITSUBISHI dealer.
  • After disconnecting the battery cable, wait 60 seconds or more before proceeding with the following work. The SRS system is designed to retain enough voltage to deploy the air bag for a short time even after the battery has been disconnected, so serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cables are disconnected.
warning
  • Certain components of this vehicle, such as air bag modules and seat belt pre-tensioners, may contain perchlorate materials. Before deployment and/or disposal of these components, review and comply with all applicable Federal, state and local regulations.
  • Do not use any electrical test equipment on or near the SRS components, except those specified on .
  • Never Attempt to Repair the Following Components: SRS-ECU, Clock Spring, Air Bag Modules, Front impact sensor, Side Impact Sensor, Seat Belt with Pre-tensioner. If any of these components are diagnosed as faulty, they should only be replaced, in accordance with the INDIVIDUAL COMPONENT SERVICE procedures in this manual, starting on .
  • Do not attempt to repair the wiring harness connectors of the SRS. If any of the connectors are diagnosed as faulty, replace the wiring harness. If the wires are diagnosed as faulty, replace or repair the wiring harness according to the following table.
  • When carrying out operations on places where SRS components are installed, including operations not directly related to the SRS air bag, do not allow any impact or shock to occur to the SRS components.

warning
  • The SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove the SRS-ECU, driver’s and front passenger’s air bag modules, clock spring, knee air bag module, side-airbag modules, Curtain air bag modules, front and side impact sensor and seat belt pre-tensioner before drying or baking the vehicle after painting.
    • SRS-ECU, air bag module, clock spring, impact sensor: 93° C (199° F) or more
    • Seat belt with pre-tensioner 90°C (194° F) or more
  • After servicing the SRS system, check the warning light operation to make sure that the system functions properly (Refer to ).
  • Make certain that the ignition switch is in the "LOCK"(OFF) position when the scan tool is connected or disconnected.
caution
  • Never heat or incinerate the airbag modules and the seat belt pre-tensioners.
  • Store components removed from the SRS in a clean and dry place. The air bag module should be stored on a flat surface and placed so that the pad surface is facing upward.
  • Be sure to deploy the air bag before disposing of the air bag module or disposing of a vehicle equipped with an air bag (Refer to GROUP 52B, Air Bag Module and Seat Belt-tensioner Disposal Procedures ).
