Hi guys: I buy a 2001 F150 crew cab 5.4 with the service engine soon light ON. After hundreds of dollars and three different mechanics light still on with high idle and some other issues. But here is my question. When I start my truck I get five dings and three seconds delay until I reach 40 miles p/h or more, then start again when I drive under 25 m/p/h. Is not the seat belt chime/alarm.Is this because the service engine soon light? Any ideas? That ding is annoying. Thank You

Thank You so much for guide me to this site. I will try those recommendations I will let know which one work for me.

 

First check the bulbs. There is one in the cluster and the one for the passenger airbag.

 

I change the air bag light in the cluster and bingo, no more ding. One little tip: Two bulbs in Auto Zone $4.99. One bulb with connector in NAPA $1.67. You can save some dollars specially if you decide to replace all (24 light on cluster)
