Speed Signal Circuit
DESCRIPTION
The combination meter assembly receives the vehicle speed signal from this circuit.
The wheel speed sensors produce an output that varies according to the vehicle speed.
The wheel speed sensor output is received by the skid control ECU, which uses this
information to create the ve ...
