Description

INFOID:0000000001089395

The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control
unit)” by CAN communication line. The combination meter then sends a signal to the ECM by CAN communi-
cation line.

DTC DETECTION LOGIC

NOTE:
• If DTC P0500 is displayed with DTC U1001, first perform the trouble diagnosis for DTC U1001.Refer

to 

EC-1073, "DTC Logic"

.

• If DTC P0500 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer

to 

EC-741, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

INSPECTION START

Do you have CONSULT-III?

Do you have CONSULT-III?

YES

>> GO TO 2.

NO

>> 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 SENSOR FUNCTION

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-III

1.

Start engine.

2.

Read “VHCL SPEED SE” in “DATA MONITOR” mode with CONSULT-III. The vehicle speed on CON-
SULT-III should exceed 10 km/h (6 mph) when rotating wheels with suitable gear position.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Go to 

EC-826, "Diagnosis Procedure"

.

4.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Select “DATA MONITOR” mode with CONSULT-III.

2.

Warm engine up to normal operating temperature.

3.

Maintain the following conditions for at least 50 consecutive seconds.

CAUTION:

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

Vehicle speed sensor

The almost 0 km/h (0 MPH) signal from 
vehicle speed sensor is sent to ECM even 
when vehicle is being driven.

• Harness or connectors

(The CAN communication line is open or short-
ed)

• Harness or connectors

(The vehicle speed signal circuit is open or 
shorted)

• Wheel sensor
• Combination meter
• ABS actuator and electric unit (control unit)

check, a 1st trip DTC might not be confirmed.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-826, "Diagnosis Procedure"
