Vehicle Speed Signal Circuit
• CAN communication with the ABS actua-
tor and the electric unit (control unit) is
malfunctioning.
• There is a big difference between the ve-
hicle speed signal from the ABS actuator
and the electric unit (control unit), and the
vehicle speed sensor signal.
• Harness or connectors
(Sensor circuit is open or shorted.)
• ABS actuator and electric unit (control
unit)

P1723 SPEED SENSOR
Description
INFOID:0000000010113671
The secondary speed sensor detects the revolution of parking gear and generates a pulse signal. The pulse
signal is sent to the TCM, which converts it into vehicle speed.
The primary speed sensor detects the primary pulley revolution speed and sends a signal to the TCM.
