Without VDC

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

The ABS actuator and electric unit (control unit) provides a voltage signal to the combination meter for the speedometer.

The voltage is supplied

from combination meter terminal 15 for the speedometer
to terminal 19 of the ABS actuator and electric unit (control unit).
The speedometer converts the voltage into the vehicle speed displayed.
