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 proce-
dure before conducting the next test.
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Start engine.
2.
Shift the selector lever to D range and wait at least for 2 seconds.
3.
Drive the vehicle at least 5 seconds at 20 km/h (13 MPH) or more.
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
4.
Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
EC-302, "EXCEPT FOR M/T MODELS : Diagnosis Procedure"
NO

Trouble diagnosis
(Trouble diagnosis content)
DTC detecting condition
Possible cause
P0500
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
(The CAN communication line is open
or shorted.)
• Combination meter
• ABS actuator and electric unit (control
unit)
• Wheel sensor
• TCM
• Output speed sensor

M/T MODELS
M/T MODELS : Description
INFOID:0000000009947417
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.
M/T MODELS : DTC Logic
INFOID:0000000009947418
DTC DETECTION LOGIC
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

>> GO TO 5.
2.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
>> GO TO 3.
3.
CHECK VEHICLE SPEED SIGNAL
NOTE:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
With CONSULT
1.
Start engine.

Warm engine up to normal operating temperature.
3.
Maintain the following conditions for at least 50 consecutive seconds.
CAUTION:
Always drive vehicle at a safe speed.
4.
Check 1st trip DTC.
Is 1st trip DTC detected?
YES

EC-305, "M/T MODELS : Diagnosis Procedure"
NO
>> INSPECTION END
5.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-304, "M/T MODELS : Component Function Check"
.
Use component function check to check the overall function of the vehicle speed signal circuit. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
