DTC Code DTC Name
C0210/33 Rear Speed Sensor RH Circuit
C0215/34 Rear Speed Sensor LH Circuit
C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC)
C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC)
C1332/38 Right Rear Speed Sensor Circuit
C1333/39 Left Rear Speed Sensor Circuit

DESCRIPTION

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the brake control system.

Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change when the rotors turn.

Each speed sensor detects that magnetic field change and sends a pulse signal to the skid control ECU.

DTCs C1273/73 and C1274/74 are cleared when the speed sensor sends a vehicle speed signal or Test Mode ends. DTCs C1273/73 and C1274/74 are stored only in Test Mode.

  4. READ VALUE USING INTELLIGENT TESTER (RR/RL WHEEL SPEED)


    1. Turn the ignition switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Start the engine.

    4. Select the Data List mode on the intelligent tester Click here.

      ABS/VSC/TRC
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      RR Wheel Speed Rear speed sensor RH reading/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) Actual wheel speed Driving at constant speed: No large fluctuations
      RL Wheel Speed Rear speed sensor LH reading/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) Actual wheel speed Driving at constant speed: No large fluctuations

    5. Check that there is no significant difference between the speed value displayed on the intelligent tester and the speed value displayed on the speedometer when driving the vehicle.

      Tech Tips

      Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart Click here.

      OK
      The speed value displayed on the intelligent tester is the same or almost the same as the speed indicated on the speedometer.
