i got this truck that was hit in passenger side and i have notice that the airbag light is on,,
but no airbags where deployed !,,
is anyone here that may know what should i do what to check,,
or if there a way to reset the light?

thank you

2002 ram 1500 2wheel 4dr 4.7

 

Not sure about the '02, but the newer trucks only a dealer could reset the light i thought?
If there is an SRS illumination, then there is a problem. There could be an issue with the module underneath the seat? Not sure which side it's located on an '02?
There could be a pinched wire, loose connection, or hopefully airbags weren't deployed and then someone just threw a new dash in without actual replacement bags because that would leave an open connection and would set off a light.
Whenever working with airbags SRS systems, you MUST unhook the battery terminals and touch them together for 5sec. This will discharge the capacitor internally within the PCM and eliminate any possibility of airbag deployment by you probing around the wires and removing connectors..etc..
So, you unhook BOTH pos and neg of the battery and then you touch those ends together.
I would first check all of the connections including up under the glove box and within the steering column(ignition source)
You should be able to test for continuity and see if there is an open line. if you have OL that means infinite resistance on the line and the other end is opened and not hooked to anything. You should see some sort of resistance. Yes, even with the battery unhooked and zero power to the truck.
If you leave the battery connected, using a test light will deploy the bags. Using a DMM will not granted you have it set on the correct setting.
I'd check for continuity with no power for starters.
Maybe PM Weedahoe and he can post up SRS schematics for you to show you locations of all the pinouts?
I'd put my money on a faulty module(located under the seat)

 

hi,
thanks for the reply!

well i got the truck hit in the front / passenger side,
and right now i am fixing with new parts,,
and i have notice the airbag light is on,,


also i have notice that the car was previously hit in driver door and rear door (driver side) and it was fixed, so not sure if the airbag light is from at that accident or the one now on passenger front,

but will try the pos and neg wires to see what will happen,
will reply,with the results,

thanks friend

 

I just seen in another thread about checking the clock spring in the steering column. I do emember a few guys saying they had to relpace that part. Worth checkin into anyways as it's part of the SRS system

 

hmm,i did disconnect pos and neg and put them for 10 sec,,,and still light comes up,

and now that clock spring is that behind the wheel steering?
do i need to take airbag down to see it?
and what is the procedure to take the airbag down?,take battery positive and negative out? first?..

thanks

 

I've got the same problem. Just started yesterday. A lot of threads talk about checking the clock spring. It is located in the steering wheel i believe.

 

There is a harness under the passenger seat with a connector. Make sure it is connected.

 

What does it look like? I am getting very annoyed!

 

Look under the seat. There is a bunch of wires. Find the connector joining the wires and make sure it is plugged up. Mine came loose and threw the light.

 

ok, i have looked also ,looks like all wires are pluged ok,
now,,to take that steering wheel out,airbag needs to come out?
do i need to take any fuse out ? so the the airbag dont blow in my face?
or...
to see that clock spring?,and how to tell if is bad,also any picture of that clock spring,?just to know what i am looking for,

thanks,
