  1. I pulled the large connector off of the Central Locking System module (under the driver's seat) and measured the discrete inputs for continuity to ground.  For most of them, I could change the input by manipulating the device (like opening the center console).  Everything seemed to work properly (see results below).  I don't know how to test the interior motion sensor input since I can't set the alarm.  I am still getting fault 34 "Interior sensor faulty" but I haven't found a faulty sensor.  I also substituted another CLS module, DME module and key transponder but the symptoms remain the same.  Does that ODB II Manual have any more ideas?

     

    Pin Function State
    5 Door safe - driver side grounded
    7 Door contact - passenger side grounded when lift handle
    13 Engine lid grounded when lid open
    15 Door lock cylinder - unlock grounded when key turned CCW
    19 Safe motor close open
    25 Door contact - driver side grounded when lift handle
    26 Center console grounded when lid open
    27 Radio contact grounded
    28 Door safe - passenger side grounded
    30 Door locked - driver side grounded when door locked
    31 Front trunk grounded when trunk open
    32 Door locked - passenger side grounded when door locked
    35 Door lock cylinder - lock grounded when key turned CW

     

    Model: 1999 996 C2 6-speed

    Symptoms: 2 beeps when locking door, passenger door does not lock, key fob button inoperative, CLS LEDs (under windshield) are dark, window up/down switches inoperative, interior lock button inoperative, interior lights inoperative, trunk/engine lights inoperative.  However, windows drop 1/4 inch when opening door from inside or out, windows roll up/down by holding door key in CW or CCW position.


  2. There are two rubber bushings that contain brass nuts used to hold down the covers on either side of the battery.  The parts manual lists them as 999-500-092-00 and I just bought two of them from the local Porsche dealer.  The problem is, they are not the same part as my 996 was built with.  These new bushings do not fit properly in my car.  I have an early 1999 996-C2 and Porsche must have changed the hole size and bushing after my car was built.  Picture shows old on left and new on right.  Does anyone have a reference for the old bushings?
