CERTAIN PASSENGER VEHICLES BUILT FOR ONE SPECIFIC FLEET CUSTOMER WERE MODIFIED FOR OPTIONAL HANDS-FREE CELLULAR PHONE OPERATING CAPABILITY. TO PROVIDE THIS FUNCTIONALITY, A SPECIAL OVERLAY WIRE HARNESS WAS INSTALLED THAT INADVERTENTLY DID NOT INCLUDE THE CIRCUITS FOR PASSENGER AIR BAG DEACTIVATION INDICATOR (PADI) LAMP FUNCTION. AS A RESULT, THESE VEHICLES DO NOT COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 208, ‘OCCUPANT CRASH PROTECTION.’
