DTC P0500 Vehicle Speed Sensor "A"


DESCRIPTION

Vehicles, which are equipped with ABS (Anti-lock Brake System), detect the vehicle speed using the skid control ECU (brake actuator assembly) and speed sensor. The speed sensor monitors the wheel rotation speed and sends a signal to the skid control ECU. The skid control ECU converts the wheel speed signal into a 4-pulse signal and transmits it to the ECM via the combination meter assembly. The ECM determines the vehicle speed based on the frequency of the pulse signal.

INSPECTION PROCEDURE

NOTICE:
  1. Inspect the fuses of circuits related to this system before performing the following inspection procedure.
  2. After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
  3. After replacing the fuel supply pump assembly, the ECM needs initialization (Click here).
  4. After replacing an injector assembly, the ECM needs registration (Click here).
HINT:
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.CHECK OPERATION OF SPEEDOMETER

  1. Drive the vehicle and check whether the operation of the speedometer in the combination meter assembly is normal.

    HINT:
    The vehicle speed sensor is operating normally if the speedometer reading is normal.
    OK:
    The vehicle speed sensor is operating normally.


NG
Go to step 7
OK


2.READ VALUE USING GTS (VEHICLE SPEED)

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch to ON and start the engine.

  1. Turn the GTS on.

  1. Enter the following menus: Engine and ECT / Data List / All Data / Vehicle Speed.

  1. Drive the vehicle.

  1. Read the value displayed on the GTS.

    OK:
    Vehicle speed displayed on GTS and speedometer display are equal.


OK
Go to step 10

NG
Go to step 3

3.CHECK HARNESS AND CONNECTOR

  1. Disconnect the combination meter assembly connector.

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    E119-6 (+S) - Body ground
    		Ignition switch ON
    		4.5 to 5.5 V

    (to Combination Meter Assembly)

  1. Reconnect the combination meter assembly connector.



NG
Go to step 5
OK


4.CHECK COMBINATION METER ASSEMBLY (SPD SIGNAL WAVEFORM)

  1. Move the shift lever to neutral.

  1. Jack up the vehicle.

  1. Check the voltage between the terminal of the combination meter assembly and the body ground while a wheel is turned slowly.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    E119-6 (+S) - Body ground
    		Ignition switch ON
    		Voltage generated intermittently

    		Component with harness connected
    (Combination Meter Assembly)
    HINT:
    The output voltage should fluctuate up and down, similarly to the diagram when the wheel is turned slowly.


OK
Go to step 6

NG
Go to step 8

5.CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - ECM)

  1. Disconnect the combination meter assembly connector.

  1. Disconnect the ECM connector.

  1. Measure the resistance according the value(s) in the table below.

    Standard Resistance:

    for LHD
    Tester Connection
    		Condition
    		Specified Condition
    E119-6 (+S) - A38-8 (SPD)
    		Always
    		Below 1 Ω
    E119-6 (+S) or A38-8 (SPD) - Body ground
    		Always
    		10 kΩ or higher

    Standard Resistance:

    for RHD
    Tester Connection
    		Condition
    		Specified Condition
    E119-6 (+S) - A52-8 (SPD)
    		Always
    		Below 1 Ω
    E119-6 (+S) or A52-8 (SPD) - Body ground
    		Always
    		10 kΩ or higher

  1. Reconnect the combination meter assembly connector.

  1. Reconnect the ECM connector.



NG
Go to step 9
OK


6.REPLACE ECM

  1. Replace the ECM (Click here).



NEXT

7.CHECK SPEEDOMETER CIRCUIT

  1. Check the speedometer circuit (Click here).

    HINT:
    Inspect the brake actuator assembly and speed sensor.


NEXT
Go to step 10

8.REPLACE COMBINATION METER ASSEMBLY

  1. Replace the combination meter assembly (Click here).



NEXT
Go to step 10

9.REPAIR OR REPLACE HARNESS OR CONNECTOR

  1. Repair or replace the harness or connector.
