Hey guys,
I have a brand new VEMS unit. I took the wheel speed signal from the instrument cluster to the cruise control, and wired it into the VEMS wheel speed input. It works and is accurate, but intermittently it will cause a no-start, the VEMS display turns on but goes blank, no COM, and no fuel pump prime.
I have measured 5v with no wheel speed at the output from the cluster. I believe it is taken from the rear diff as a VR sensor, and then converted to a digital signal and sent to the cruise control (which is where I'm picking it up).
Should I grab it from the sensor itself, or am I missing something?
Thanks,
Sam
