got a problem...I know someone can help.

alright guys,

I would post this under a more "technical" category but I figured I would have a better shot posting this here for you Lexus guys who are more experienced with 1st Gen LS 400's (specifically, the 91 LS 400).

Early last week, a chip board behind my instrument cluster burnt out and started smoking, which in turn made the backlighting turn off also.

I immediately ordered a used 1992 LS 400 cluster online that came out of a (obviously) 1992 LS 400 WITH height control.  My 1991 LS 400 did not come with height control, no biggie, I installed it anyway and everything went well (I even have that cool little neon green "height control" display on the bottom left of the cluster although I don't have height control lol).  Everything works fine except for one noticeable thing...

...the airbag light is now permanently on, however, the airbag light never came on on my last cluster.

any ideas of why this might be happening?  is it a problem?  is there a way to fix it (or is it even necessary to fix it)?

experienced 1st Gen LS 400 owners, help a fellow LS4 brother out. Thanks- (arigatou)

go to a dealership or to autozone or somewhere that can pull the faults. more than likely the car that this cluster came out of was in an accident and the airbags went off and the light was not cleared. or it could be a coincidence that now you have a bad airbag

i'm thinking the bulb was burned out or removed in your old cluster. start by looking at that. there's a specific way to clear the srs light, it's time involved, maybe if you search clublexus or something you might be able to find a way to do it..

found the answer.  it happens when you remove your cluster, drive your car for a while without the cluster, and then replace the cluster.

I agree. Same thing use to happen to my old SC400 when you removed the cluster and turned on the ignition. Anyway, I no longer have the instructions to pull and reset the airbag code, but if you search Club Lexus in the SC forum you probably will find it. You pull the code just to verify that it is indeed just the cluster pulling/turning on ignition problem and not something else, then you reset the airbag code by jumping a few pins in the OBD port and grounding, ungrouning the pins in a certain sequence. At least that is how it was for my SC400 of the same era.

Never mind. I see the link provided above has the instructions. :)
