Have a question about the at/p light on my 1991 fj80 today i noticed that the light came on the dash when i was sitting in my drive way in park, when i pulled the transfer case to nuetral then back to high the light when off, then about 1 min later the light slowly started to come back on. It is also not as bright its pretty dim, but if i shift the tc lever back to n its at its full brightness. It also shuts off when I shift the tranny to drive, Any ideas why it does that?

On my driver's visor there is a notice that reads:
A.T.P. THIS LIGHT INDICATES A.T. PARKING IS IN AN INACTIVE CONDITION. SHIFT TRANSFER TO "H" OR "L" POSITION. REFER TO OWNER'S MANUAL WHEN P.T.O. IS OPERATED
I went out to my 80 and if the t case is in neutral and the transmission in park the ATP light will illuminate. I think it is a warning (hence the red color) to remind you that the truck is not in park because the t-case is in neutral.
The owner's manual refers to it as the Unengaged "Park" warning light and reads as follows:
This light warns that the transmission "Park" mechanism is not engaged. If the four-wheel drive control is in the "N" position while the selector lever is in the "P" position, the transmission will disengage and the wheels will not lock.
CAUTION:
To restore the park function, shift the four-wheel drive control out of "N".
If you are sure that you are fully engaged in high or low then your switch is probably to blame.
Hope this helps,
Dave

I realize this an old thread, but my A/T P light came on in the dash a day ago.
I have checked that the transfer case is in High and the fluid is good in the tranny.
Is there anything else I should check? Did you get it to go off?
Also has anyone else had this same problem? What can i do?
Thanks,

Wrong forum and 10 year old post that most likely had to do with the switch on the t case that senses the neutral position. Way to goLooks like not a common occurrence as most 100s doing soccer mom duties
Jokes aside got it on during transfer is on N and went away right after putting in to H
