If DTC U1000 or U1001 is displayed, first perform the trouble diagnosis for DTC U1000, U1001. Refer to
EC-492, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The vehicle speed signal is sent from vehicle speed sensor (models with ABS) or ABS actuator and electric
unit (control unit) (models with ABS) to combination meter. The combination meter then sends a signal to the
ECM through CAN communication line.
Diagnostic ProcedureEBS00KLF
1.CHECK VEHICLE SPEED SIGNAL OVERALL FUNCTION
With CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Select “VHCL SPEED SE” in “DATA MONITOR” mode with
CONSULT-II.
4. Make sure that “VHCL SPEED SE” indication exceeds 10 km/h
(6 MPH) when rotating wheels with suitable gear position.
Without CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Read vehicle speed with combination meter.
Make sure that vehicle speed indication exceeds 10 km/h (6 MPH) when rotating wheels with suitable
gear position.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2.CHECK DTC WITH VEHICLE SPEED SONSOR (MODELS WITHOUT ABS) OR ABS ACTUATOR AND
ELECTRIC UNIT (CONTROL UNIT) (MODELS WITH ABS)

OK or NG
OK >> GO TO 2.
NG >> Repair or replace.
3.CHECK COMBINATION METER

System DescriptionECS007O2
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
