DTC P0500 Vehicle Speed Sensor "A"


DESCRIPTION

The skid control ECU outputs a signal that is proportional to vehicle speed. This signal is based on the rotation of the ABS wheel speed sensors. After this, the signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter. It is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of this signal.

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
After replacing the ECM, the new ECM needs registration (see page RAV4_ACA30 RM000000TJ4007X.html) and initialization (see page RAV4_ACA30 RM000000TIN007X.html).
1.CHECK OPERATION OF SPEEDOMETER

  1. Drive the vehicle.

  1. Check the speedometer reading in the combination meter.

    УКАЗАНИЕ:
    If the vehicle speed sensor signal is inaccurate, the speedometer will show abnormal readings.
    OK:
    Speedometer operates normally.

CHECK SPEEDOMETER CIRCUIT (INCLUDE SPEED SENSOR)
OK


2.READ VALUE OF VEHICLE SPEED

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine and turn the tester ON.

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

  1. Check the vehicle speed at an engine speed of 2,000 rpm or more while the vehicle is running.

    OK:
    Same value as actual vehicle speed.

  1. Disconnect the E22 combination meter connector.

  1. Disconnect the A12 ECM connector.

  1. Measure the resistance of the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    E22-39 (+S) - A12-14 (SPD)
    		Below 1 Ω
    E22-39 (+S) or A12-14 (SPD) - Body ground
    		10 kΩ or higher

  1. Reconnect the combination meter connector.

  1. Reconnect the ECM connector.
