P1709 INCOMPLETED DATA WRITING

Description

INFOID:0000000009949018

When TCM does not store calibration data (individual characteristic value) of each solenoid valve that is
stored in the ROM assembly (in the control valve), a malfunction is detected.

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.)
