steering module?
Hi guys.
I have a 2007 gl450 (gas) that I bought to revive and make a daily, maybe. It had sat for 2 years, dead, in someones yard etc. Anyway, got a battery, got it cleaned up, and it started right off.... I was impressed. However, as things have progressed, I have the following issues.
1. NO data to OBD port... it has power, powers up, but no connection. I have XENTRY/DAS and cannot read anything. The multiplexer powers up, but no dice.
2. NOTHING on the steering wheel works. Doesnt move, no buttons light, and MOST of the time wont shift. Sometimes the park is lit up, hit and miss.
3. Windshield wipers do not work, turn signals dont work - emergency flashers do - Randomly the wipers will cycle once.
4. All, literally, of the warning lights come on and go off randomly....head lights flickered once even, but sometimes they are all off... (runs great)
5. tach mostly doesnt work.
6. No audio from stereo - tried cd and radio both. Acts like it works, but no noise.
The floor board was wet.... curious.... dont know why. Anything hidden down there that will cause problems? (Drivers side, front)
Cooling fans work, runs great, once it did go into drive and drove great.... but now back to all of the above.
Does it have a 38 pin port somewhere in addition to the odbii? I have all the cables if so. Would the steering control module cause all of this? (No shift, blinking random warning lights, etc) Does the steering module have to be coded in? How to do this without ODBII port working if so? Any other ideas?
I have removed rear sam, cleaned all connections (none were bad), removed grounds front and rear, cleaned up, (none bad), and plugged and unplugged everything I can find.... all to no avail and nothing has made any remote change.
What am I missing?
I think that the part number for the steering control module is 164-545-87-16-80.. can anyone confirm? (I havent removed or investigated it much yet. Anyone repair them?

take a good look at other places where water collects such as the trunk before you decide to go any further with this - it might be a parts car, or you might get very lucky.

The central gateway module corrected 95% of everything. Also ended up putting in airmatic control module. All steering controls came back, keyless entry / keyless go all came back, etc. no warnings at present, other than self inflicted for a coding error telling it the car had ADS on the airmatic when it didnt.... beating my head on the wall trying to figure out where i coded that. Anyone knows, please share.

You solved all of my problems and it was a humbling experience.... we have been working on these things for 20+ years... you zipped through it like you were reading the paper. I am impressed and thankful both!!
