Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Speedometer Malfunction; 2019 - 2021 MY RAV4 RAV4 HV [11/2018 - 12/2021]

Speedometer Malfunction

DESCRIPTION

for HV Model:

  • The combination meter assembly receives vehicle speed signals from the brake booster with master cylinder assembly (skid control ECU) via CAN communication. The speed sensor detects the wheel speed and sends the appropriate signals to the brake booster with master cylinder assembly (skid control ECU). The brake booster with master cylinder assembly (skid control ECU) supplies power to the vehicle speed sensor. The brake booster with master cylinder assembly (skid control ECU) detects vehicle speed signals based on pulses of the voltage.

    HINT:

    • Factors that affect the indicated vehicle speed include the tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using the Techstream. For details about testing and the margin of error, see the reference chart.

    • If the vehicle speed sensor circuit has a malfunction, the brake booster with master cylinder assembly (skid control ECU) stores DTCs. Troubleshoot the electronically controlled brake system.

for Gasoline Model:

  • The combination meter assembly receives vehicle speed signals from the brake actuator assembly (skid control ECU) via CAN communication. The speed sensor detects the wheel speed and sends the appropriate signals to the brake actuator assembly (skid control ECU). The brake actuator assembly (skid control ECU) supplies power to the vehicle speed sensor.

CAUTION / NOTICE / HINT

NOTICE:

  • If the vehicle speed is outside the allowable range when tested, perform the operation check.

  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

HINT:

Before starting the following inspection, check tire size and tire air pressure.

PROCEDURE

1.

CHECK CAN COMMUNICATION SYSTEM

(a) Check if CAN communication DTCs are output.
