How to connect
To be able to connect to the ecu we first need a INPA / K-Line capable USB to OBD2 adapter. Some cheap china INPA cables won't work properly without modifying them to get them workin correctly you need to short Pin 7&8 on the OBD2 plug.
You can also use Logger.S instead
You will need the following connections to properly power up the DME while on the bench.
There are several different wirings that could be used, but we have found that this is the least amount of wires needed for a properly working setup:
Sometimes, using the K-Line connector on plug X60001 Pin 3 doesn't work, in that case you have to use X60004 Pin 25.
There are two different CAN bus interfaces on the MS43, one for the TCU located on plug X60002, and one for all other modules like ABS, ASC/DSC, instrument cluster, steering angle sensor located on plug X60004.
