The LIN wire comes from Pin 20 on the door module , the LIN wire from BLISS camera and Rear door module both come in to connect at the PDM at pin 20 ..
you need to determine first if there is a digital signal on this data wire .. it is a 12v signal rapidly switching on/off .. an oscilloscope is the best way of looking at it . but if you get a small LED with a series resistor of about 400 ohms , connect its negative to earth and use the positive to probe the LIN wire you should make out a rapid flickering if the signal is there ..
the fault code indicates the signal is faulty ..
If your basic continuity checks on teh LIN wire is ok , you have to assume the PDM is not sending it out or sending out an incorrect signal .
Another problem may be the BLIS or Rear door module is corrupting the signal , so disconnect the LIN from first the rear door module and see if BLIS works , Then disconnect it from the Mirror camera and see if the rear door works ..
My feeling is the PDM is faulty ..

So what will you say if after testing all this and yet still the camera does not WARM UP, what does it means...
