I started to look into my problem further to see what causes my limb home mode! I want to get to the bottom of this if I can!

- I have the circuit diagram showing all the connections to the N4/1 control unit! It is not that bad the unit does not get that many inputs.

- I check all the cable going from N 4/1 to the throttle actuator - the are fine and no shorts for sure! THE ONLY SURPRISE was that the switch S1 in the throttle actuator has a very high resistance of about 1200 Ohms. The switch S2 in the throttle actuator has a couple of Ohms (THis is what I expected). However, I check on a working throttle actuator and get the same results. Confirmed by others... on the block..

- I check the connections to the main control module N 3/4 - They are fine!

- I check the function of the brake switch as well as the cruise control switch and they all work as they should!

- The other inputs are from the ABS unit and the A/C! I assume that the system would light up the ABS light if anything is wrong with the ABS unit! NO ABS light is on!

- I also think that the A/C would not be able to trigger the limb home mode...

- Also the voltages are supplied from the Overvoltage protection relay

NOW THE QUESTION ARISES WEATHER THE MODULE N 4/1 IS SHOOT! I HAVE A USED ONE COMING!

DO I MISS ANYTHING?

CAN ANY OTHER MODULE TRIGGER THE LIMP HOME MODE? - THE LIMP HOME MODE IS ONLY MENTIONED IF THE N#?$ UNIT DOES NOT GET VOLTAGES REPRESENTING THE POSITION OF POTENTIOMETER R1 AND R2 IN THE THROTTLE ACTUATOR FROM N 4/1!
