I have a R56 2010 Automatic with the shifter paddles and keeps intermittently tripping and clearing a P0997 code which is S2 circuit high. Any ideas?. I'm trying to trace wires to find a break and I don't know what goes where so was wondering if anyone had a pin out of the main transmission plug to the two on the front shown in the picture or the whole pinout. My Chiltons Manual doesnt show me squat.

Wiring harness that plugs to ecu

ECU slot

connectors that are on the transmission

 

Side note for anyone shooting wires from the TCM to the transmission plugs, here's the pinouts

TCM under the driver side dash that's tucked away near the steering column has 2 plugs. One has 24 Pins (C1), the other has 18 (C2). On the transmission side one plug has 8 the other has 14.

First plug with 8 wires
1 ---> C1:1
2 ---> C1:7
3 ---> C1:6
4 ---> C1:12
5 ---> C1:24
6 ---> C1:17
Pin 7 and 8 are unused

Second Plug with 14 Wires
1 ---> C2:4
2 ---> C2:5
3 ---> C2:11
4 ---> C2:17
5 ---> C2:10
6 ---> C2:17
7 ---> C2:9
8 ---> C1:19
9 ---> C2:8
10 ---> C1:13
11 ---> C2:12
12 ---> C2:15
13 ---> C2:13
14 ---> C2:16
