Warning light for airbag/seat belt pretensioners

Put key in on position for ten min to reset system...thieves cant wait that long

These two faults maybe unconnected. Starting with the seat belt warning. There should be a switch in the seat to check if someone is sitting in it and a switch in the seat belt catch to check if the seat belt is engaged. If either of these switches or the wiring to them is faulty then the light will come on if the ignition switch is turned on. The airbag warning will come on if there is a problem with the explosive that operates the bag or wiring to it. I would check under the front seats of your car for wiring damage or a not fully engaged plug and socket. These can be damaged or work loose if things have been pushed under the seats.

the air bag light is telling you the system has failed/disabled to locate the problem you need to get the fault code out of the airbag control module using a obd code reader the norm cause is damaged wiring/bad connectors under the seats for the seat belt pretensioners disconnect the connectors and apply contact grease refit and retest

2005 Towncar SRS Code 33 (3 flash + 3 flash, repeat this set for twice. then Beep 5 times pause x 5 = 25 beeps every 30min).

This means you have problem with left (Driver) side pretentioner (Seat belt retract system).
It doesn't mean physical belt or retract mechanism.It is just bomb wiring which is part of airbag system.
When airbag deploy, passenger must stay tight in seat otherwise body lean to front then slam back to seat by airbag.
if belt is loose or delay to lock, passenger's body rocks back and forth.So, system use small bomb (Fire power) to lock and retract seat belt when airbag deploy.There is small bomb and igniter in part of Seat belt retractor.
Code 33 is warning for this part on 2005 Towncar.(older model is different meaning in Ford/Lincoln, it's possibly passenger side airbag system for earlier model)
Before you work for any part of Airbag system and touch any "Yellow connector", * *Disconnect battery (negative side is good enough) and wait at least 5 min to clear all power in system**.(Airbag store back up power for few minutes to be able to deploy even in case if power disconnected)
by the way, you should move your driver seat most forwarded position before you disconnect battery to make it easy to work with seat belt.
locate driver side seat belt retractor (in center pillar between front and rear door, you may have to fight with weather strip)

Locate Yellow connector on bottom of Seat belt retractor (it's called "Pretensioner")it is located on very bottom of rear side of retractor.
only one yellow connector. (make sure your battery is disconnected)
Check its physical connection or looseness.if connection looks fine, you may have to replace whole seat belt ($180-$200 in Lincoln dealer)
You can check if pretensionor is good or bad by regular tester, but unless you know how, I won't tell (because I don't wan't you to blow out pretentionor).

If the airbag light is on something in the system is broken. Go to AutoZone or similar and have them scan the airbag system for codes. My guess would be a faulty seat sensor or a faulty seat belt sensor

dont think you can it should reset itself when you turn ignition off and on again but its a merc so no doubt its done like this so its a dealer only job ,hope you have lots of wedge to pay the dealer

It sounds like 2 different problems. The dead battery is most likely caused by a bad alternator or an "Ignition-Off Draw" (Something staying on after the ignition is turned off) The SRS light means that there is a problem with your Supplemental Restraint System. This could be caused by an airbag circuit or a seat belt pretensioner circuit. You will have to scan your Restraint System Module to find out why it has turned the light on.

From the F-150 Forums, since I just bought one and this worked!

This is straight from my 2009 f150 owners guide

Preperation
1. the parking brake is set
2. truck in park
3. ignition switch is in off position
4. both seat belts are unbuckled

Disable Belt-Minder
1. turn the ignition switch to the on position, DO NOT START THE ENGINE.
2. wait until the safety belt warning light turns off. (approximately 1 minute).
* step 3 must be completed within 50 secs after the safety belt warning light turns off.
3. buckle then unbuckle the seat belt nine times, ending in the seat belt unbuckled.
* after step 3 the restraint warning light, (airbag light) will turn on for three (3) seconds.
4. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
* the restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation

you can do this for the passenger side also!!!


*NOTE
in step 3. after three times buckling and unbuckling the restraint warning light lit up in my truck. SO I WENT TO THE NEXT STEP, (STEP 4). waited 3 seconds and i buckled and unbuckled.

in the buckle /unbuckle procedure do it some what slowly and watch for the light. it may not take 9 times.

you may have 2 problems 1 ightion switch and a seat belt pretensioner both faly common problems

look to see if you can adjust your seat belt pretensioner to better suit your height. look at the top of your seat belt- ( driver's side up and to the left of your left shoulder ) and see that you can very easily slide up or down your seat belt pretensioner. you are actually supposed to do this and even redo it if you ever readjustt your seat up or down or forward or backwards. believe it or not, your safety airbag light will come on automatically until you adjust your seat belt pretenioner in a way that the sensors read your seat belt to be safely set. naturally, if someone else drives the car he or she might have to readjust the seat belt pretensioner for the sensors to read them as being safely put. do this and the airbag warning light should go out.
