Dash warning lights

Post by **Crawls** » Sun Nov 10, 2019 3:00 pm

Hey everyone, I am trying to figure out a dash light on my 90 MR2. It is a green light that has "A/D" on it. I have no idea what it is, or whether it should have a bulb in it. The car is a NA Auto. Any ideas?

It appears it's part of the cruise control (auto drive) system. Indicates it is active or an error has occurred. Just looking through my Japanese service manual and that's what it says.

Awesome, but my car doesn't have cruise control.

Well that's no use to anyone haha.

Has it always been on since you've owned the car? Has it had the gauge cluster swapped for another one?

Well the bulb was blown since I got the car. I am changing all the bulbs to LEDs and found it was blown. Same as the engine fan one in the pic. That pic just has daylight going through it haha. Had all but 5 blown.

Don't know if cluster has been replaced. But I suppose it is possible.

If it doesn't have Cruise Control then nothing to worry about. Just put the bulb socket back in place without a bulb or LED and leave it at that.

I am replacing all the dashlights, and correct me if i am wrong. there are a T10 bulb for illumination, a T5 bulb for warning lights, but what is the bulb for the Auto selection lights (P,R,N etc)

Haven't replaced them before since I don't have an auto SW. Should be T5 though since T10 is normally only for background light in dash clusters.

Looks like it from this:

The auto lights are slightly smaller. i think they are T4 but am not sure.

They are a NEO fitting but I can't be sure what number. 3, 4 or 5.

Interesting, never sold them before. People don't really replace them though

Were they sold new without the bulbs if Cruise Control was not installed, or even without the bulb holder too?

Without the bulb.

Yea I wouldn't but only one works. I kinda like everything to work, no matter how "pointless"
