Hello, I am wiring up an aftermarket gauge cluster (koso rx2n) and I need to know a few things about the VSS signal waveform coming out of the ECU A18/ C101 pin3 for the speedometer.
What is the peak voltage?
What is the frequency in relation to vehicle speed (I just need a general ball park figure)?
VSS signal waveform info
Re: VSS signal waveform info
The ECU does not output this signal. This is an input from the VSS sensor on the transmission.
Re: VSS signal waveform info
So is it a 12v peak waveform?
Edit: Nevermind I just found it... its a 5v pulse.
