‘99 Nissan Maxima, Airbag Warning Light
Q: I own a ‘99 Nissan Maxima and for the past few days, the Airbag warning light is not going away and it starts blinking once the engine starts. I try to reset by the traditional method like press the door sensor 7 times and all the stuff, but it’s still on. Could you please guide me on this?

A: Doing the thing your doing with the door switch just switches the airbag computer system from user mode to the diagnostic mode. Each time the ignition switch is turned off the computer resets to the user mode of operation. If there is no system problem, the warning light will turn on and then off after about 7 seconds when the key is turned on. Because the warning light stays on after the vehicle is started, means the problem or system fault is still present. The user mode alerts the driver of the vehicle to a system malfunction, by turning on the air bag light and/or the set beat warning light. The way the warning light flashes, stays on or off for a specified time directs the technician to which diagnostic procedure he or she must use for diagnosis. By pressing on the driver's side door switch 5 times in 7 seconds (with the key on) the computer is being switched into diagnosis mode. Because of the system complexity, it is best that you have diagnosis performed by a technician that is familiar with the system used on the Maxima by Nissan. Playing around with an airbag system can cause some very undesirable results if you get across the wrong wires.
