Just finish up my 1jz swap. I got no reverse light and the airbag light is on 24/7.

Anyone have any idea what could cause these? I've search thru the forum, couldn't find anything about these fix.

 

I don't have reverse lights either. What year is your car? Mine's a 95 and I solved the 3k rpm problem and the airbag light by clipping one of the body plug wires.

 

Car is a 92. Engine is also a 92.

 

I had the perma-airbag light also. I pulled the bulb. Need some sc400 wiring diagrams to figure out why the dash light has been getting power full time

 

well i just bought a 92 sc400 auto, my neutral lights stays on and it does not show my parking or reverse light and when i put it on low gears my parking lights come on. i think it wired wrong or something any idea lol? not a big deal for a really good price got on it.

 

One Jay,
If you have the service manuals, can you PLEASE PLEASE trace that wire in the manuals to say where it originates and what it is in the manual. I've been waiting for someone with the manuals to post up the info.

 

I don't have it. Sorry.

 

Going to look thru the sc300 diagrams soon and will try to figure it out. Stay tune.
