what could this be for?

 

Low Radiator fluid, high temp, low coolant pressure...probably the first, check your coolant level.

 

That's actually the carnival button. It tells you when you are close to any carnivals/circus'. Hehe, j/k, it's what UZZ30-SC4 said.

 

i thought it meant you were near the Lincoln Memorial

 

Stew's ready.

 

it supposed to mean your low on coolant. It could also mean your sensor is broken and nothing is wrong. The latter is what happened to me.

Also i know later model sc400s have the sensor removed. I guess because they realize it can become faulty.

 

In that case there must be no speedo needles, alternators, PS pumps, center bearings, LCD's, engine and transmission mounts, MAF's.............

 

guess not. Better technology

 

Same stuff actually! even the needles. Mount differently to avoid compatibility, but same SMD's.

 

How cool. What year SCs did these come on? Ive only noticed them on the LS.

 

The coolant sensor? Its on sc400s only because of their unique (high quality) coolant reservoir. Not sure what year they stopped putting the sensor in but 92s have the light/sensor.

Here is a pic of the ls400 reservior, looks similar to the sc400 one right?
You can see the sensor its yellow and the rubber around it is peeling off. Its the exact same style as on the sc400. Newer model sc400s still have the hole for the sensor, but its capped off.

 

i guess so

 

Do you have the sensor?

 

Yeah I hate the way they peel back and WILL NOT stay friggin wrapped around the disc.

 

Im almost sure. Haven't actually seen it. Aren't these type of things in the manual anyway?
