456 GT WSM Motronic 2.7 Section

My 456GT WSM (2.7 Motronic) is missing pages C3 to C-67 which covers the 2.7 Motronic diagnostic procedures and codes (does not seem like an accident).

Does anyone have this section?

Thanks in advance.

 

I asked the 348 Forum. Will ask the 355 if I do not hear anything.

 

This is what the 348 forum told me

This works for pulling and resetting codes. Takes a bit of practice initially. Thought I would add it to the thread. Credit to Ernie off FChat.

Okay guys I have some more info on pulling the codes. You may have only pulled one code out of the ECU. After you get the first set of flashes giving you the numbers for the first code you need to move on to get the next code from the ECU. What you have to do is hold the button down again for :02.5 - :05 seconds, then the ECU will give you the next set of flashes for the following code stored in the ECU. At the beginning of each set of code flashes there is a long flash indicating the beginning of the sequence. After all for numbers have been flashed there will be a pause, and it just starts over again, with the long flash indicating the beginning. Now after it has gone through the series of flashes, what you want to do is wait until the last number is flashed, then hold the button down during the long flash 02.5 sec) and let go in the middle of the pause. This will get you to the next stored code. As I said before the next code will start with a long flash, then a pause, then the flashes start for the next code. You just keep doing this until you have pulled all the codes out of the ECU. When all of the codes have been pull you will get nothing but long flashes. When you are at this point, that is when you want to hold the button down for :10 seconds to clear the codes out.

 

Here is a link (at least until it gets taken down) to the 2.7 Motronic section from the 355 manual. Good enough to figure out our 12s.
