Q: I have a 2000 lincoln LS V6 3 litre 5 spd. About every 5-10 mins it beeps 5 times. after about 45-60 mins it beeps 5 times in a series of 5, then returns to the first pattern. What does this mean??
A: The reason your car beeps is because there is a problem with the air bags and the air bag warning lamp is not working. We find this problem often in cars bought from used car lots, rather then repair the airbag system so the light will be off they remove the bulb. Considering the supplemental restraint system is important I would recommend finding a qualified repair facility to fix them, there is a good chance it will have to be taken to a Lincoln dealer. Below is a copy of a paragraph from the Ford service manual describing this condition. When the ignition is cycled (turned off and then on), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash the two-digit LFC associated with that fault. The air bag indicator will flash the LFC five times, then remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the data link connector (DLC), using the New Generation Star (NGS) Tester. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the instrument cluster to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.
