Hi,
I just finished installing my UTCOMP-PRO in a 2006 V6 Hilux.
Everything worked straight away apart from the VSS signal.
I used the VSS signal wire between the instrument cluster and the ECU. I have checked for circuit continuity
between the VSS wire and the UTCOMP pin A22, which is ok.
Is there anything else I can check ?
Thank you

Re: VSS Signal
Have you checked this signal with oscilloscope or voltmeter? (it should be 0-12V pulses when car is moving).
If you will not have these pulses than you have connected wrong signal.
If you will have pulses on UTCOMP input than it has to work
In this case you can also check UTCOMP's input by switching input (manually) to 12V and GND (it should count pulses).
