'84 Toyota Cressida: Runs Fine, But Every Dash Warning Light Is Lit. Thoughts On ?

Hello,

Here's an interesting one.

My wife has a '84 Toyota Cressida waggon.
Her pride and joy; very low mileage on it, about 43 K only.
Best car we ever bought.

Live outside of Boston, and car has always been left outside.
Car starts up just fine as always, and seems to run just fine.
No problems.

But, when turning the ignition on, and it stays this way while driving,
just about every warning light on the dashboard is illuminated.

Lights I don't think I've ever seen before, or even knew where the

e.g., in orange:

Rear Lights
Fuel
Washer
Doors

and in red:

Battery warning light

But everything's fine.
Car runs normally, plenty of fuel, battery is charged, etc.

Any thoughts on what might be happening ?

Much thanks,
Bob
