92 Self test threw 536 code while engine was off

[cliffjumper87]

So I ran both the engine on and off self tests this morning and got 111 and 536 with the engine off, and 111 with the engine on. Far as I know, the 111 codes mean it's good, but everything I can find about 536 is for when the engine is running. Any ideas?

Isn't that some sort of air conditioner code?

It's not, it's something to do with the brakes. Most stuff I could find said it means you pushed the brake during the engine on test cycle
