copied & compiled from other group I've posted...

2005 Aston Martin DB9

Chapter #1

Actual diagnostic error shows NO communication with LEFT ECM, also there is a NO KEY error on instrument cluster display plus temp gauge goes all the way up.

Any tip or advise that lead me to solve this issue?

Chapter #2

I have restored communication with BOTH ECM's... but still have a issue.

ERROR KEY and the temp gauge goes ALL THE WAY UP..

Any ideas??

Error codes are as follows:

B1600 No key code received
P0705 Transmission range sensor circuit malfunction
P1000 System Check not completed (its nothing..)
P1797 CAN transmission control module to engine control module malfunction. (This one worries me..)

Chapter #3

I have done some more test on this car.
I disconnected the transmission plug to check CAN lines. I find out that there is NOTHING on pin #2 (CAN L) and pin #6 (CAN H)
No voltage as expected (2.4 + V) or ohms reading..

Checked also pin #13 / 16 for ground Its OK

Checked pin #14 for POSITIVE (perm) its OK

So, my question is..... who's the module before TCM ? I want to check the transceiver output on that module.

Any one with this info??
