OK,

My headlight auto-levelling warning light has come on in the car. While I had the car in for a quick service, I had them plug in the car to get a code, but apparently, no code comes up for that warning light. How do you know what to replace? Or do you just replace both front and rear components to fix it? Anyone know how much they go for? Thanks alot...

 

did you recently lower your car, or put a lot of stuff in the trunk, or go uphill a lot?

 

that just happen to me this week ... my headlights were going up and down as i was driving then wen it stoped the warning lights turned on and it doesnt move again i got some info from the toyota dealership where i workd told me that the measurement of the green fluid bar (leveler) were to tell if your going up hill and downhill were malfunctioning.. and so i hope its coverd in my warrenty .... but yeah what i believe in is that green measurement bar (leveler) that is causing the headlights going up and down... .. ill try to get some pictures to update

 

My green levellers look fine. That's what I mean...how do you tell which part is faulty? Is it the servo motos on the drivers side front and rear? It would seem to be extremely expensive to just start replacing everything..

 

Try resetting the ECU and see if they come back. I take it right now the light is on and the autolevel feature isn't working?
Thats pretty tough to troubleshoot if it doesnt' throw a code.

 

Guys with the air runners air setup, can you mess up the leveling sensors when you dump the car?

 

ooh yeah my gs is @ my dealership where i work @ and the certified tech told me that he researchd and its not the headlight leveler... what he think may be that theres a troubleshooting @ the leveler in the rear of the car because he put the car up on the lift and the headlights were moving up and down.. so yeah as to my car its still in the service bay... waiting for the results .. so ill try to update the problem..

 

Ok..outstanding. Please let me know what your results are, and what the approximate cost for parts is. Cheers! ~R
