H0162 Vehicle Speed Output Signal 1

[Lennart]

The help text does not say where to find that signal on an E38.
The C1-57 is supposed to have a 128K signal, but where is the 4K signal available?
I really would like to find this signal to feed into my LS1B to get the speedo and ABS
back to work !

What E38 tune are you using - i.e. 2008 Escalade, etc. ?

Set H0162 to "Serial Data". The 4K pulse Speedometer signal will be on ECM C1 (Black) pin 57. Depending on the speedometer type you are using - you may need to wire a pull up circuit to amplify the output.

Hi Taz,

will give it a try. The signal is going to the 99 PCM VSS input (C2 Pin 21). Do I just put the low reference of the VSS (Pin 20) to ground?
