Default Disassembling and examing the overhead console (2001 model)

I've been wanting to tear into this one for a while. I don't like cheesy green LCD stuff at the best of times, and I can bang a lot more fun toys in that thing.

Thanks to @oldcoach for his post on how to remove this in the first place:
How do I remove the overhead console?

Our PTC is a 2001 Touring Edition, so the overhead console is temperature, compass and map lights only. The purpose of this thread is to examine what we have in here and how it works. From there, I can start working on what I'm going to do to this console, however that will be a semi-tutorial kind of thread. First, let's rip into her!

----

Removal was fairly straightforward as per Oldcoach's instruction. Even in my weak pneumonia-wracked state, I got it off in seconds.

There was a small black plastic enclosure loosely clipped through the hole in the headliner to the roof, containing a small PCB connected to the console via a long ribbon cable. I suspect this might be the compass. The entire console is otherwise connected to the main car loom via a single multiconnector which is easily disconnected by pushing the retention clip in and providing a little pressure on the wires coming out.

Firstly, the basics. Figure out what is onboard, and what comes in/goes out.




It looks like this connector is partially populated with (eight) pins from a maximum of twelve. These must correspond to functionality that the Touring Edition doesn't have/need, specifically a power sunroof....

Five of the eight wires lead straight to the LCD section of the console, leaving three to manage the overhead courtesy lights. I am presuming that these would simply be a +Vcc (battery or alternator voltage ~12,5VDC) and GND plus an override for the courtesy lights based off the panel lamps driver bus.

Let's look at the onboard PCB....

Meh, it seems these are typical vertical market auto ICs same as those found in the front power window switchbox managing the current sensing for auto window wind and limiting. We'll treat that as a black box for the moment and maybe logic out which are the power lines, which is connected to the temperature sender, etc.

Let's take her out of the casing and see what magical innards there are to see....

Remove the three screws holding the rubber de-wobbling retention thing:




Pop one side of the courtesy light lens with a screwdriver (plastic spudger preferred of course):




Then the other:






These two clips in either lens cavity and the two screws inside hold the subassembly to the console fascia. Pop 'em.




Slide the subassembly out to the right to disengage the big flat tab at the left:




Static precautions be damned.




Man, that's so '80s.

Okay, so let's see what we have here....




Hmm. NEC microprocessor, timing crystal (to the right of the MPU) plus some ancilliary items. Well, in spite of the vast majority of the silicon around the PTC being your typical undocumented OEM stuff, we can identify that BA10324AF chip. Unfortunately, it's a pretty vanilla quad op-amp/comparator. Another thing that could probably be logic'ed out, but totally not necessary unless you want to get in really deep.

This seems to be an interesting resource that my Google-fu turned up:

http://www.autozone.com/repairguides...96b43f802e2b12

Judging by these diagrams, the pinout of the 12-pin connector (the only way in/out of the console) should be:

1 - Power Sunroof Open
2 - Power Sunroof Switch Ground
3 - Courtesy Lamps Driver
4 - Constant +VCC
5 - Ambient temperature sensor signal
6 - Run/Acc +VCC (ignition power)
7 - Power Sunroof Vent
8 - Power Sunroof Close
9 - GND
10 - Panel Lamps Driver
11 - Ambient temperature sensor signal ground
12 - GND

(italicised entries not applicable in Touring Edition)

So from this we can tell that the compass is definitely that small outboard PCB on the ribbon cable. The only information that the console is receiving from the outside world is whether the car is in Run/Acc mode, the courtesy and panel lamps driver voltage plus the temperature sensor. This makes the console more or less of a standalone item, which is great from a modification standpoint....I wonder if that temperature sensor can be read from an Arduino....?

This thread serves purely as documentation on disassembly and what there is to see in this console. Beyond this thread, I'll be using this information to make a better Arduino-powered rotary compass and temp sensor reader using an OLED display, plus maybe even adding in low-power Bluetooth to interface the display in with the Android tablet console.
