Remote Locking Update

2738 Views 9 Replies 3 Participants Last post by  awaschka
I still haven't solved my remote locking problem, but I have more data. I have tried both the factory synchronization procedure and the alternate procedure posted here, with no success. When using the factory procedure, whichever button I press after holding lock and pressing unlock five times works. Then nothing else works. When using the alternate procedure, nothing works. I bought a Carsoft tester and the AAM is reporting code B1858, "fixed code OK but not released". My MB maintenance DVD says this is a transmitter problem or a synchronization problem, or an antenna problem. One member here reported that changing the AAM fixed this problem. I'm inclined to believe that the problem is in the AAM as whichever button I press after pressing unlock 5 times works, the system just won't synchronize. Any ideas?

Thanks,

Al

It's an update to what?

Your post from 2006 about start error?
Your post from 2008 about remote? Never followed up.
Your post from 01/2009 about central locking?
With all due respect, I thought the subject line was pretty clear. That would seem to exclude the first post you asked about. The second one you listed basically had no help for this problem, and focused on the key removal problem. The third post you listed had no replies.

So what is the point of your reply to this post? This is an ongoing problem, and I was looking for some help from, what has been in the past, a helpful venue. Unfortunately none of the previous responses I got were of much help. Since then I purchased a set of diagnostic software. The troubleshooting steps in the Star Service DVD aren't much help (it's either the key, the AAM, or a synchronization problem) , so I reported the code here hoping someone might have more insight to my problem. BTW, I contacted my local indy repair shop and he says he can't help with a potential AAM problem, that's a dealer only item. Can you help me with this problem, or not?
Subject line is clear but. We don't know what is production date (month/year) and model of your truck.

If this is an update attach to previous post.

There is diagnostic menu that shows live data in AAM. It shows which key button is pressed. It can be used on another working vehicle to confirm that your keys are sending correct values. Can you access that screen?
What is your truck key history? How many keys ware issued? Did those keys ever worked? If so what lead to loss of synch?

Find shop that can look at list of keys and their status in AAM. Keys can be selectively enabled/disabled.

Here are few screen shot that show some AAM menus.
