Using Navigation to Check Diagnostic Codes

[glanga]

I can't remember exactly but I can see how this might help future members.

For those who have factory navigation with their LS I remember you could go into the programming section by holding the top and bottom button simultaneously next to the nav screen until a keycode pad comes up. I can't remember the code but when you enter it, it takes you in a whole car diagnostic system like current exact elevation, lat+long, bearing. Also audio diagnostics like a self test.

I remember seeing another feature but I could never try it because I never remembered to when I had a check engine light on. I'm pretty sure it allowed you to pull up diagnostic trouble codes that the car's computer was throwing.

Was I imagining this or does it work, has anyone used it?

CEL codes...No.

I'm pretty sure it did. It interfaces with the car's computer and it took a few seconds to scan and it'd show a code if you had one

I think the new Chebys have some sort of feature like that.

CEL codes...No.

So what else he is saying is true? What is the code to get in after you push the buttons if in fact this is true?

Yeah, hold the top and bottom buttons next to the screen simultaneously for 5 seconds. A screen comes up prompting a pin. It's 1791 I think or 1971. Inside there is all sorts of cool little things to mess with.

Don't push "software update" or else it'll wipe itself clean unless you have a firmware update disk.

Just realise you can be messing with stuff that isn't supposed to be messed with.
