P1720 VSS
DescriptionINFOID:0000000012431605
ECM receives two vehicle speed signals via the CAN comm
unication line. One is sent from “ABS actuator and
electric unit (control unit)” via combination meter, and the other is from TCM (Transmission control module).
ECM uses these signals for engine control.
