Reseting CEL and Radio anti-theft on '92 T4R, need help.

[FastCat]

Hi everyone! I'm a new T4R owner and I've found this forum very helpful in determining what to look (out) for when shopping for a used 4Runner. I recently bought a '92 4runner, and have a couple questions I'm hoping y'all will know the answers to.

The sound system is factory - a cassette, tuner, and CD player combo. My problem is the original owner doesn't remember the anti-theft code, and I understand that if power is ever removed (like disconnecting the battery), I'll need to enter the code to be able to use the sound system again.

The reason I want to disconnect the battery is (as I understand it), that is how you reset the Check Engine light. I have a code indicating a bad O2 sensor, and once I swap it out, I'll want to reset the CEL, but I'm afraid I'll be killing the sound system if I do that.

So, two questions:

1) Is there a specific fuse to the ECM that will allow me to reset the CEL without disconnecting the battery?

2) Is there a way to find out the radio's anti-theft code or reset it to some known default?

I hope these are basic questions that can be answered easily!

Thanks in advance!

Remove the 15A EFI fuse for about 30 seconds in the fuse box under the hood and this will cancel the code without killing the radio.

As far as resetting the radio code Oz Toy dealers will do it if you verify the car is yours Check your dealers as its a common problem with cars being resold etc etc.
