Car Forum / Toyota / Toyota Cars / November 2005Corolla seatbelt warning incorrect (sometimes)
I seem to remember seeing this in relation to a Sienna but I am not 100% sure. The seatbelt indicator on my 1999 Corolla LE is sometimes off when the belt is not pulled out and off when the belt is pulled around me [this is correct] but at other times it is OFF when the belt is fully retracted and BLINKING when wrapped around me (and clicked, of course). Having never driven without a seatbelt for the last 32 years the light is quite an irritant. If I pull the belt out just a little bit further the light goes off again so I guess I could gain another 10 pounds or so! Does anyone know anything about this? Will it affect my side/front airbag deploy? Any other info appreciated. Andy >I seem to remember seeing this in relation to a Sienna but I am not 100% > sure.

Check the opening in seat belt receptacle to see if anything is stuck in there like a coin. A foreign object in the receptacle is the most common cause of your complaint. When the seat belt light is blinking, the belt may feel like it is secured but it probably is not because the foreign object makes if feel like it is engaged. The airbags offer a lot less protection if the seatbelt is not worn properly and securely because if the latch releases, your body won't be positioned correctly for the airbags to work. The switch in the seatbelt receptacles are very reliable - I've never seen one fail but I have seen lots of coins, paper clips, hair pins, spilled liquid residue in there.

Correct Ray, the seatbelt is the driver side. I will get in there with with a good flashlight and check for objects. Thanks for the response.

Good luck! SignatureRay O correct the return address punctuation to reply OK, after inspecting the belt mechanics as much as I can without disassembly it strikes me we are on different wavelengths here. When you say receptacle I NOW imagine you mean the snap thing. If so, this is NOT how my belt determines worn/not worn. The snap is easily seen and there is no wiring going to it at all. The way my belt does worn/not worn is by how far the belt is pulled from the roller (in the door post). Now, I WAS able to pull the cowling off slightly and look inside there and down at the roller but not enough to see what does the sensing. A switch in the snap would be great! Don't know why that is not the case. So, the question is do I understand you right; do other Corollas have switches in the snap like normal cars?

When you [quoted text clipped - 13 lines] > > Andy I am not familiar with the seat belt in your car but I have never seen a seat belt warning circuit set up like you are describing. This is because of the wide range of occupant sizes, and it would be possible to defeat the flashing light just by pulling the seat belt out far enough In other words, how would the car know if the occupant has a 30 inch waist or a 50 inch waist, especially given that the seat can slide forward and back? The wiring is more likely in the female receptacle, what you are calling the "snap thing." If the chimes and warning light go out when you snap the seat belt in and not when you just pull out the belt, then it has to be in the receptacle. More likely, you can't see the wires. Did you look inside the receptacle and poke around?

Don't forget that some makes use a 'weight switch' also...IOW a switch mounted 'under' the seat which tells whether there's an occupant sitting there... -- -Gord. Keep in mind that I'm an expert with questions, so if you have any, fire away. Be aware however, that answers quite often give me trouble. >> OK, after inspecting the belt mechanics as much as I can without >> disassembly it strikes me we are on different wavelengths here.

Trust me here, there is no switch inside the recepticle and no place to hide wires AND the belt has never waited to be plugged into the receptacle to switch off. Strange but true. While in "reverse mode" pulling the belt out further turns the indicator off even though it has been plugged in all the time. I have never seen such a thing either but it is the case. This is a 99 corolla with side air bags if I failed to indicate that. > Trust me here, there is no switch inside the recepticle and no place > to hide wires AND the belt has never waited to be plugged into the [quoted text clipped - 3 lines] > either but it is the case. This is a 99 corolla with side air bags if > I failed to indicate that. image link bellow = Recepticle from both sides. Flat steel about 1/8" thick and 1 1/4" wide. No wires, no switches. If anyone knows how to access Toyota parts drawings/info via net (expect that is not likely) let me know otherwise I appreciate the time. I will take the full cowling off the door post and examine the roller up close and see how it works and hopefully why it whacks out now and then.

Thanks TeGGeR! I know just what I plan to do now.

Andy, Let us know what you find in the receptacle!

I have not "gone in" yet but all I plan to do on mine is disable the switch since I am the only driver and after driver over 30 years with a seatbelt I don't really need to be reminded. If you need the indicator to work correctly you will need to replace the seatbelt retractor switch or try to repair it. Two separate documents describe the switch as open and closed with seatbelt worn so I don't yet know if I will need to unplug the switch or unplug then jump the connector. Andy >> > I seem to remember seeing this in relation to a Sienna but I >> > am not 100% [quoted text clipped - 16 lines] > > Andy To follow up. While I don't offer this as a recommendation, if one wants to disable the seatbelt indicator and is willing to assume responsibility for those who may need the indicator to remind them to wear the belt (!) you must remove the plug from the SB retractor and provide a jumper on the plug to simulate the retractor. at this point you will no longer have a belt warning indication. Andy Could you please post some info on where this switch is (is it in the little snap on / click unit in which the seatbelt clip clicks ?) and if possible where I can buy the replacement. I'm having the same problem and want to find a solution. Any possibility of posting the info on the documents you found ? Any help is highly appreciated.

No. Not on a 1999 Corolla Le. The switch is part of the seatbelt roller (retractor) which is near the bottom of the door post behind some plastic cowling. It is called a seatbelt retractor switch. > Look inside the seat belt recepticle and remove the foreign object > lodged in there. You could unplug the wire from the roller and jump the connections with a piece of wire (the plug is on the side of the roller which faces the back seat. OR You could purchase a new part which may be the entire roller assembly and expensive. > (is it in the >>> little snap on / click unit in which the seatbelt clip clicks ?)

I have the same problem with the 98 corolla LE. The light on/off when or when not the seat belt is off/on. I have unplugged the switch in the seat belt retractor area and the light remains on and I plug it in and it is not relible. Do you suppose it could be not a good connection?? Also when my DRL are on the instrument panel lights are on and when I monkeyed with the seat belt switch I noticed that the instrument panel lights were off when the DRL was on.

The most likely cause of the seat belt light problem is a foreign object in the receptacle. SignatureRay O correct the return address punctuation to reply |
