EXCEPT FOR M/T MODELS : Description
INFOID:0000000012198519
ECM receives vehicle speed signals from two different paths via CAN communication line: One is from the
ABS actuator and electric unit (control unit) via the combination unit and the other is from TCM.

NOTE:
• If DTC P0500 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P0500 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer to
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.

VEH SPEED SEN/CIRC
(Vehicle speed sensor)
At 20 km/h (13 MPH), ECM detects the fol-
lowing status continuously for 5 seconds or
more: The difference between a vehicle
speed calculated by a output speed sensor
transmitted from TCM to ECM via CAN com-
munication and the vehicle speed indicated
on the combination meter exceeds 15km/h
(10 MPH).
• Harness or connector
(CAN communication line is open or
shorted.)

M/T MODELS : Description
INFOID:0000000012198522
The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control
unit)” via the CAN communication line. The combination meter then sends a signal to the ECM via the CAN
communication line.
