DISARMING THE IR SYSTEM


Proper and safe operation requires the sensor, brackets and wiring to be installed in the exact locations of design. The information provided is to help you understand the system and disarm the system if other non-air bag system service are to be performed. Before beginning the disabling procedure, read all service precautions.




  1. Turn the steering wheel so wheels are facing straight ahead and turn the ignition switch to the LOCK position. Remove the key from the ignition.



  2. Disconnect the negative battery cable and tape the end of cable to avoid possible terminal contact.

To avoid personal injury, wait at least 30 minutes after disconnecting the battery cable before servicing the IR system on 1987-91 Delta 88/Eighty Eight models. Servicing the IR system during that period of time may result in personal injury.


  1. Remove the IR fuse from the fuse block.



  2. Remove the left side sound insulator and lamp.



  3. Disconnect the IR inflator connector from the base of the steering column.



  4. If necessary, connect the negative battery cable. The system is now safe for servicing.



ENABLING THE SYSTEM


Before beginning the enabling procedure, read all service precautions.




  1. Disconnect the negative battery cable and tape the end of cable to avoid possible terminal contact. Remove the IR fuse.



  2. Reconnect the IR inflator connector at the base of the steering column, if disconnected.



  3. Install the sound insulator and lamp, if removed.



  4. Install the IR fuse and connect the battery cable.



  5. DISARMING THE SIR SYSTEM


    See Figures 12, 13, 13, 14, 15 and 16


    Proper and safe operation requires the sensor, brackets and wiring to be installed in the exact locations of design. All components service must be exactly aligned and tighten to exact torque specification. It is not advisable to service the air bag system. The information provided is to help you understand the system and disarm the system if other non-air bag system service are to be performed.


    Before beginning the disarming procedure, read all service precautions.




    1. Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.




      1. Turn the ignition switch to the LOCK position, remove the key, then disconnect the negative battery cable.



    2. Wrap the end of the battery cable with tape to avoid possible terminal contact.



    3. Remove the AIRBAG fuse (fuse #7 for 1992-93 vehicles, or #1C for 1994-99 vehicles) from the fuse block.




    With the AIRBAG fuse removed and the ignition in the


    RUN position, the AIR BAG warning lamp illuminates. This is a normal operation and does not indicate a system malfunction.




    1. Remove the left side sound insulator/steering column filler panel and courtesy lamp, as needed.



    2. Remove the Connector Positive Assurance (CPA) lockpin on the yellow 2-way connector at the base of the steering column.



    3. Unplug the yellow 2-way SIR connector, located near the base of the steering column.

    1. If equipped with a passenger side air bag, remove the right side instrument panel sound insulator to access the connector. Remove the CPA lockpin, then unplug the yellow 2-way passenger inflator module connector. The connector is located at the base of the right side instrument panel, clipped to the knee bolster (tie bar and steering column filler).

    1. If necessary, connect the negative battery cable. The system can now be safely serviced.




    ENABLING THE SYSTEM


    Before beginning the enabling procedure, read all service precautions.




    1. Make sure the ignition switch is in the LOCK position, then remove the key from the ignition.



    2. If not already done, disconnect the negative battery cable and tape the end of cable to avoid possible terminal contact.



    3. If equipped with a passenger's side air bag, attach the yellow 2-way connector and the CA to the inflatable restraint instrument panel module pigtail. Install the right side instrument panel sound insulator.



    4. Reconnect the SIR 2-way yellow connector at the base of the steering column. Reinstall the CPA lockpin on the yellow connector.



    5. Install the left side sound insulator/steering column filler panel and lamp, if removed.



    6. Install the SIR fuse in the fuse panel.



    7. Connect the battery cable.



    8. Staying well away from both air bags, turn the ignition switch to the RUN position and check that the INFLATABLE RESTRAINT/AIR BAG lamp flashes 7-9 times and then goes out.



    9. That's all I got!
