## NHTSA's summary

Air Bag Warning \- Resistance Related Fault Codes. Condition: Air bag warning displayed. Service: To be applied to applicable cars exhibiting fault codes as detailed above. Although the fault codes may only be appertaining to one side of the car at the time of complaint the new harness must be fitted in its entirety, integrated into both the drivers and front passengers seat belt real assembly. The procedure consists of electrically disconnecting the original wires connecting the air bag control module to the front seat belt reels. This is done by cutting off the ends of the connectors at the seat belt reel end and de\-pinning the main connector housing at the control module end, the redundant wires are then taped back into the main harness. The new harness is then connected to the components and secured to the main harness.
