Vehicle Speed Signal Circuit
• TCM detects a malfunction of CAN com-
munication between ABS actuator and
electric unit (control unit)
• When vehicle speed that TCM detects is
10 km/h (7 MPH) or more, vehicle speed
signal (CAN signal) that is received from
ABS actuator and electric unit (control
unit) is less than 2 km/h (1 MPH)
• Change of vehicle speed signal (CAN
communication) that TCM receives is
large
• Harness or connectors
(CAN communication line is open or
shorted.)
(Vehicle speed signal circuit is open or
shorted.)
• ABS actuator and electric unit (control
unit)
VSP SENSOR
: More than 10 km/h (7 MPH)
