Front Impact Sensors

WARNING: BEFORE BEGINNING ANY AIRBAG SYSTEM INSTALLATION OR REMOVAL PROCEDURES, REMOVE AND ISOLATE THE NEGATIVE (-) BATTERY CABLE (GROUND) FROM THE VEHICLE BATTERY. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

THE FASTENERS, SCREWS, AND BOLTS ORIGINALLY USED FOR THE AIRBAG COMPONENTS HAVE SPECIAL COATINGS AND ARE SPECIFICALLY DESIGNED FOR THE AIRBAG SYSTEM. THEY MUST NEVER BE REPLACED WITH ANY SUBSTITUTES. ANY TIME A NEW FASTENER IS NEEDED YOU MUST REPLACE WITH THE CORRECT ONES PROVIDED IN THE SERVICE PACKAGE OR ONES LISTED IN THE PARTS BOOKS.

6. From PASSENGER side of vehicle, turn the ignition key to "ON" position. Exit vehicle with DRB II.

7. After checking that no one is inside the vehicle, reconnect the negative battery terminal.

8. Using the DRB II, read and record any fault data including stored faults.

9. Refer to the Diagnostic Test Manual if any faults found in previous steps.

10. Erase fault codes using DRB II.

NOTE: IF PROBLEMS REMAIN, FAULT CODES WILL NOT ERASE.

11. From the PASSENGER side of vehicle, turn the ignition key to "OFF" then "ON", and observe the instrument cluster airbag light. The light should go on for 6 to 8 seconds, then go out. The system is functioning normal.
