EXCEPT FOR M/T MODELS
EXCEPT FOR M/T MODELS : Description
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.
EXCEPT FOR M/T MODELS : DTC Logic
DTC DETECTION LOGIC
NOTE:
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0500 | VEHICLE SPEED SEN A (Vehicle speed sensor “A”) | At 20 km/h (13 MPH), ECM detects the following 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 communication and the vehicle speed indicated on the combination meter exceeds 15km/h (10 MPH). |

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
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.
Is 1st trip DTC detected? YES >> Proceed to EC-330, "EXCEPT FOR M/T MODELS : Diagnosis Procedure" NO >> INSPECTION END
EXCEPT FOR M/T MODELS : Diagnosis Procedure
1.CHECK DTC WITH TCM
Check DTC with TCM. Refer to TM-108, "CONSULT Function".
Is the inspection result normal? YES >> GO TO 2.
NO >> Perform trouble shooting relevant to DTC indicated. Refer to TM-126, "DTC Index".
2.CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
Check DTC with ABS actuator and electric unit (control unit). Refer to BRC-31, "CONSULT Function (ABS)".
Is the inspection result normal? YES >> GO TO 3.
NO >> Perform trouble shooting relevant to DTC indicated. Refer to BRC-43, "DTC Index".
3.CHECK DTC WITH COMBINATION METER
Check DTC with combination meter. Refer to MWI-17, "CONSULT Function (METER/M&A)".
Is the inspection result normal? YES >> GO TO 4.
NO >> Perform trouble shooting relevant to DTC indicated. Refer to MWI-26, "DTC Index".
4.CHECK OUTPUT SPEED SENSOR
Check output speed sensor. Refer to TM-178, "Diagnosis Procedure".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace or replace error-detected parts.
5.CHECK WHEEL SENSOR
Check wheel sensor. Refer to BRC-68, "Diagnosis Procedure".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace or replace error-detected parts.
M/T MODELS
M/T MODELS : Description
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
DTC DETECTION LOGIC
NOTE:
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0500 | VEHICLE SPEED SEN A (Vehicle speed sensor “A”) | The vehicle speed signal sent to ECM is almost 0 km/h (0 MPH) even when vehicle is being driven. |

DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT? Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 5.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure 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
Is the inspection result normal? YES >> GO TO 4.
NO >> Proceed to EC-333, "M/T MODELS : Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
Is 1st trip DTC detected? YES >> Proceed to EC-333, "M/T MODELS : Diagnosis Procedure".
NO >> INSPECTION END
5.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-332, "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 >> Proceed to EC-333, "M/T MODELS : Diagnosis Procedure".
M/T MODELS : Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
With GST
The vehicle speed signal on GST should be able to exceed 10 km/h (6 MPH) when rotating wheels with suitable gear position.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-333, "M/T MODELS : Diagnosis Procedure".
M/T MODELS : Diagnosis Procedure
1.CHECK DTC WITH ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
Check DTC with ABS actuator and electric unit (control unit). Refer to BRC-31, "CONSULT Function (ABS)".
Is the inspection result normal? YES >> GO TO 2.
NO >> Perform trouble shooting relevant to DTC indicated. Refer to BRC-43, "DTC Index".
2.CHECK DTC WITH COMBINATION METER
Check DTC with combination meter. Refer to MWI-17, "CONSULT Function (METER/M&A)".
Is the inspection result normal? YES >> INSPECTION END
NO >> Perform trouble shooting relevant to DTC indicated. Refer to MWI-26, "DTC Index".
