Does the 2500HD have a "front passenger seat occupant sensor"? I want to add heated seats to my LMM, and if I have the occupant seat sensor, then some brands of heaters can't be placed over the grid sensor.
My local dealship doesn't know but they said to check to see if my truck has a auto or remote pass seat airbag disconnect. This is either a keyswitch in the glove box=manual, or a idiot light on the "overhead console"=automatic. I have looked in the glove box, and no key switch (I know what to look for as my last truck had this feature) and my overhead console doesn't have any light to illuminate if my passenger seat is occupied (for the airbag system) nor is there anything on the instrument panel. I could pull off the leather seat bottom to check, but this seems like a lot of work when the answer may be here somewhere here on The Diesel Place.:(

Mine does, and the easy way to tell would for someone to ride in the front passenger seat without thier seatbelt. There will be a few dngs and a red light with the seatbelt warning with a X2 next to it.

Mine does not have any sensers on the passenger side. No key in glovebox and no light on above dome light so........IDK

Thanks for both of the replies....would you guys confirm that you both have LMM's. How about if this is a trim level......LT versus LTZ? My owners manual says that I should have one or the other (mine is a LT1) but it doesn't look like it to me.

By federal law..........it's either got to have the disconnect, or the sensor. My '08 2500 HD has a sensor. If you have an LMM purchased in the US, and it doesn't have a key..........then it's got a sensor.

Mine is the LMM and the SLE trim, which is like the chevy LT2. I cant find a senser under the seat so if that is true then its true but my brother has a 1/2 ton new body and he has the light by the dome light and I dont.

What I would like to know, is why my manual says that I have the keylock (glovebox) or the overhead console. I have neither!!
I quess that I may have to pull the leather cover off of the seat to check.
Even calling GM with my VIN didn't answer any questions. Anyone else have any ideas?

Well.........it's there. My '08 2500HD CC SLE 4x4 threw code 5 minutes out of the dealership.....the DIC displayed an error for the airbags........the problem was the sensor unit......the wiring got caught in the power seat track.

This sensor arms the airbags only if the front passenger is heavy enough......it's to prevent injury to kids or smaller adults. All manufactureres have to either install the sensor, or provide a manual means (the keylock) to disable the passenger airbag.

If you got a shop manual.........just look at the wiring schematic, or get underneath your passenger seat and trace the wires.

It is Delphi's PODS B system. The sensor is a pressure sensitive bladder under the "B" side of the foam. It acts as a OCS (Occupant Classification System) and in some cases, a decontented "Passenger Presence Detection System"

FMVSS requirements state that the HD trucks do not need them. However, it seems that GM did put them in some trucks, but not all. I think 3500's don't have them...

I called the DRE to get ask details...I'll edit the post to set things straight.

After speaking with the seat DRE, all HD trucks do NOT have PODS-B systems. You should not have OCS sensors in any of the HD trucks.

Thanks!

After further review and seeing other posts, you'd better check to make sure. Sounds like Ewbish knows for sure that he has one in his truck. Although my intel is telling me NONE of the HD trucks has OCS.

Ewbish - Which plant was your truck made? Fenton?

And to further increase my post count...
Just talked to another gentleman deeper in the system, none of the seats built for HD series Pickup trucks (2500 or 3500), are built with OCS sensors in the seats. Not sure about what GM is doing with the key switch or telltales (the lights in the overhead/mirror). Regardless, no sensors in the seats.

I thought that the ones that had the sensors also had the light that told you it was off/on in the overhead console. The 1500 I drove, as a rental, had it right up top by the dome lights, where there is a blank panel in mine. 3/4 and 1 tons have had different airbag laws for a long time. Remember that the classic body didn't get airbags until 01, when they changed them. My 2000 didn't have them. I wouldn't be surprised if they didn't have a sensor or switch.

I'll have to look.......don't remember. Far as the sensor, the airbag warning came on with an error message in the dic. Took it to the dealer, and showed him how the warning light and error would go out if I let the seat go all the way back. They pulled the seat and found the sensor wires were bound up in the seat motor......this is what they told me and wrote on the repair order. He showed me the wiring harness after it was removed from under the seat.......and pointed to a specific set of wires which he described as going to the airbag sensor in the seat.

fornt seat air bags are suposed to have a sensor for the front seats. for any thing under 40 lbs they will not go off. there howerver may not be a light that tells u its on or off because its irelavent. if the pasanger is under 40lbs you do not wnt the air bag going off anyways

Crew cabs dont get the key switch to lockout. Reg cabs get them because there is no where else to put a child car seat.

DING!

We have a winner.


Reg cabs AND EXT cabs.

It was confirmed that NONE of the HD trucks have OCS sensors in the seats (at least thats what the seat DRE says). Buckle switches & SPS (seat position sensor) will throw codes if faulted. Their inputs go to the SDM. It was likely one of those...

Fire0021 - You are correct but only for 1/2 ton trucks. HD trucks are not required to have OCS systems per FMVSS requirements.

I do thank you guys.... I decided to stick my head under the front passenger seat today just to have a look! There is an electrical connecter under the seat near the floor that isn't attached to anything. A further look shows that the pass seat does not have any wires or connectors under it. I would have to say that my passenger seat does not have a occupant grid sensor...at least not wired into the truck. I now feel fairly safe in thinking that I can add heated seats to both front seats.:)

I've had my passenger seat apart to add the heated seat mat and............there is NO occupant seat sensor!!!

I don't think mine has one of those weight sensor things but I do know that my 07.5LMM has a keylock in the dash and the little light that illuminates whether the passenger airbag is on/off above my head...hope that helps some...
