4X4 Light On only - HELP!!!!

[rogerkiu]

I guess you might encounter alternator problem. You should have got over 14v when the engine is running if your alternator is working fine, however, you said it was only 13.x. I don't think it is the angle sensor, because you would have had all lights up including ABS, brake light and 4x4 light if your angle sensor goes wrong. Run a test on the alternator.

Is there a non-invasive way to test the alternator? I'd like to rule that out without pulling it off the car...

Check out the other thread on the DSC, ABS and 4x4 with posts from this morning. QSilver put instructions on how to check your alternator volatge from your cluster.

I've been testing via the OBC already.

I have a little voltage/battery tester that I bought on AMAZON some time ago, it plugs into the cig lighter and gives digital readings....high when driving was 13.85 low after overnight was 11.74. Battery is about 2 years old provided by CPO warranty.

This is pretty similar to where i'm at monitoring via the OBC.

I don't know about others...but your images aren't visible on my work CPU. Are you uploading them as attachments in your posts...or do you have them uploaded to an image hosting website that has assigned them a URL?

It could also be my employer's server doing net nanny on me if the hosting website is not approved.

I'm using the image URL after I post them on twitter. I had a buddy check the URL to this thread and he could see them. They are also showing up on my iPhone. Might just be your employers firewall.

Ahhh! There's my problem...twitter is not an approved site for some businesses due to the personal nature that site can take (consider the once esteemed Congressman Anthony Weiner).

Hmmm, at this point, there is entirely too much guessing. Qsilver hit the nail on the head with the battery, but at this point voltage doesn't seem to be your problem. This may suck, but you are going to either have to take it to the stealer to have the code read or a indy shop who has GT-1 to get the code. No time for guessing anymore. Mine came on this morning but also read "4x4 Inactive" on the cluster. After a restart, the light went away. Things like this occur because of voltage. As of now, my voltage regulator is on its way out. But for you, the story is different.

TwinsPoppa had the same problem a few months ago, luckily he has a GT-1 and it spelled out SAS. So he DIY'd it himself. You got to spend a few bucks to get the fault back, but atleast you can stop guessing.
